Where can I get an X-based PostScript previewer? Ghostscript is distributed by the Free Software Foundation (617-876-3296) and includes a PostScript interpreter and a library of graphics primitives. Version 2.5.2 is now available; the major site is prep.ai.mit.edu. [11/92] GSPreview (by the Computing Laboratory of the University of Kent at Canterbury) is an X user interface (WCL-based) to the Ghostscript 2.4[.1] interpreter [5/92]. The source is available for anonymous ftp from export.lcs.mit.edu as gspreview.2.0.tar.Z. Ghostview (by Tim Theisen, tim@cs.wisc.edu) is full-function user interface for GhostScript. Check ftp.cs.wisc.edu or prep.ai.mit.edu for /pub/ghostview-1.4.1.tar.Z [1/93]. There are also several executables available on ftp.cs.wisc.edu:/pub/X/ghostview-exe for various architectures. Also: ScriptWorks is Harlequin's software package for previewing and printing PostScript(R) descriptions of text and graphics images; previewers for X are available. For information call +44-223-872522 or send email to scriptworks-request@harlqn.co.uk. Image Network's Xps supports the full PostScript language and renders in color, grayscale, or monochrome. Fonts displayed are anti-aliased. Info: Image Network, +1 415 967 0542. Digital's dxpsview runs on UWS 2.1 and 2.2. Sun's pageview runs with the X11/NeWS server. ---------------------------------------------------------------------- Subject: 84) Where can I get an X-based GKS package? The latest freely-available XGKS can be obtained from xgks-request@unidata.ucar.edu; this is a 2c implementation derived from the X11R4 contrib XGKS from IBM and the University of Illinois. The release is on unidata.ucar.edu [128.117.140.3] as pub/xgks.tar.Z. [12/90] In addition, Grafpak-GKS is available from Advanced Technology Center (714-583-9119). GKSUL is available from gks@ulowell.edu (ULowell CS department). It is a 2b implementation which includes drivers for a variety of devices. It can be passed an X window ID to use. The package includes both C and Fortran bindings. [11/90; from dsrand@mitre.org and from stew@hanauma.stanford.edu] An XgksWidget is produced by Neil Bowers (neilb@leeds.dcs; neilb@dcs.leeds.ac.uk); the latest [10/91] conforms with the new version of XGKS (2.4). It is available on export in contrib/xgks-widget.tar.Z. ---------------------------------------------------------------------- Subject: 85) Where can I get an X-based PEX package? The first official release of PEX is with X11R5. The final PEX 5.1 Protocol specification is now available via anonymous ftp to export.lcs.mit.edu (18.24.0.12), in the directory /pub/DOCS/PEX/. Changes made from the Public Review draft are listed in the file "5.1P_changes" in that directory. [9/92] The final PEXlib 5.1 document is on export in pub/DOCS/PEXlib. [11/92] There is now available from the University of Illinois an implementation of the PEX 4.0 specification called UIPEX. It contains a "near- complete" implementation of PHiGS and PHiGS PLUS. The file pub/uipex/uipex.tar.Z is on a.cs.uiuc.edu (128.174.252.1); the porting platform was an RT running 4.3. Questions and comments can to go uipex@cs.uiuc.edu. In addition, the PEXt toolkit by Rich Thomson (rthomson@dsd.es.com) is available on export as PEXt.tar.Z; it includes a PEX widget making it easier to include PEX in Xt-based programs. ---------------------------------------------------------------------- Subject: 86) Where can I get an X-based TeX or DVI previewer? The xtex previewer for TeX files is available from a number of archive sites, including uunet; the current version is usually on ftp.cs.colorado.edu (128.138.204.31) in SeeTeX-2.18.5.tar.Z; pre-converted fonts are also on that machine. The distribution all includes "mftobdf" which converts PK, GF, and PXL fonts to BDF format, where they can then be compiled for use by your local X server. The xdvi dvi-previewer is fairly comprehensive and easy to use. It is also available from a number of sites, including uunet and export.lcs.mit.edu; current version is patchlevel 16 [12/92]. ---------------------------------------------------------------------- Subject: 87) Where can I get an X-based troff previewer? X11R4 has two previewers for device-independent troff: the supported client xditview, and the contributed-but-well-maintained xtroff. An earlier version of xtroff also appeared on the R3 contributed source. xditview is also in the R5 distribution. In addition, the xman client can be used to preview troff documents which use the -man macros (i.e. man pages). If psroff is used its output can be viewed with a PostScript previewer. In addition: xproof, an X previewer for ditroff has been contributed by Marvin Solomon (solomon@cs.wisc.edu); version 3.5 is available on export in contrib/xproof*. [8/90] Elan Computer Group (CA: 415-964-2200) produces eroff, a modified troff implementation, and Elan/Express, an X11 eroff previewer. SoftQuad (416-963-8337; USA only 800-387-2777, mail@sq.uu.net or mail@sq.com) offers SoftQuad Publishing Software, including a substantially- rewritten troff formatter, a better intermediate language with backwards compatibility, and an X11[R3,R4] previewer. (This is the package adopted by AT&T's own MIS department, and used in and re-sold by many parts of AT&T). [information from Ian Darwin, SoftQuad (ian@sq.com) 3/90] Image Network (1-800-TOXROFF; CA: 415-967-0542) offers the Xroff package, which includes a fine modified troff implementation and a set of X11-based page previewers. (This is the package OEM'ed by several hardware vendors.) [mostly courtesy moraes@cs.toronto.edu (Mark Moraes)] [2/90] ---------------------------------------------------------------------- Subject: 88)! Where can I get a WYSIWYG interface builder? A new release of the DIRT interface builder by Richard Hesketh works with X11R5 and includes some support for the Motif widget set. From the README: This builder allows the interactive creation and rapid prototyping of X user interfaces using the X Toolkit and a number of Widget Sets. Dirt generates "Wc - Widget Creation" resource files and this distribution also includes the Widget Creation Library (version 1.06, with the exception of the demos and Mri/Ari source code) with the kind permission of its author David E. Smyth. Check dirt.README, dirt.A2.0.tar.Z, and dirt.PS.Z on export.lcs.mit.edu. The InterViews 3.0.1 C++ toolkit contains a WYSIWIG interface builder called ibuild. ibuild generates code for an InterViews application complete with Imakefile and an X-resource file. Documentation is /pub/papers/ibuild.ps on interviews.stanford.edu (36.22.0.175). Quest Windows's (408-496-1900) ObjectViews C++ package includes an interactive building tool. Druid (Demonstrational Rapid User Interface Development) runs on SPARC machines using OSF/Motif 1.0; it is intended eventually to be a full UIMS but apparently now has only support for creating the presentation components, for which it generates C/UIL code. Info: Singh G, Kok CH, Ngan TY, "Druid: A System for Demonstrational Rapid User Interface Development". Proc. ACM SIGGRAPH Symp on User Interface Software and Technology (UIST'90). ACM, NY, 1990, pp:167-177. The BYO interface builder is implemented in tcl. Also: In addition, these commercial products (unsorted) are available in final or prerelease form [the * following the product name indicates that the product is known to allow the designer to specify for each widget whether a particular resource is hard-coded or written to an application defaults file, for at least one form of output].

In addition, Neuron Data (1 415 321-4488) makes Open Interface, a window-system-independent object toolkit which supports interfaces which are or resemble (supersets of) Mac, Windows, and Motif and Open Look; the package includes an interface builder. In addition, the GRAMMI builder supports the development of Ada/X applications using its own set of objects which are planned to have a Motif look. GRAMMI is written in Ada and generates Ada specs and stub bodies. (1-800-GRAMMI-1). In addition, these non-WYSIWYG but related products may help for goals of rapid prototyping of the application interface: WCL: the Widget Creation Library. Basically describes the widget hierarchy and actions in a resources file; available from fine archive servers everywhere, including devvax.jpl.nasa.gov (128.149.1.143) in pub/. Wcl provides a very thin layer over Xt without any internal tweaking. 2.03 became available 11/92; version 2.04 will be available before 12/16/92. WINTERP: an Xlisp-based Motif toolkit allows for interpretive programming. The copy on the R4 tape is outdated; get a copy off export or email to winterp-source%hplnpm@hplabs.hp.com. The Serpent UIMS permits the building of user-interfaces without specific knowledge of coding but with an understanding of attributes being set on a particular [Motif] widget. Beta Release 1.2 is available from ftp.sei.cmu.edu (128.237.1.13) and can be found in /pub/serpent. Serpent is also available on export.lcs.mit.edu (18.24.0.11) in /contrib/serpent. Email questions can go to serpent@sei.cmu.edu. A commercial version of Serpent is available as "Agora" from ASET, 221 Woodhaven Drive, Pittsburgh, PA 15228. Garnet is a Common Lisp-based GUI toolkit. Information is available from garnet@cs.cmu.edu. MetaCard is a hypertext/Rapid Application Development environment similar to Apple/Claris Corporation's HyperCard (info@metacard.com). MetaCard is available via anonymous FTP from ftp.metacard.com, csn.org, or 128.138.213.21. ---------------------------------------------------------------------- Subject: 89)! Where can I find X tools callable from shell scripts? I want to have a shell script pop up menus and yes/no dialog boxes if the user is running X. Several tools in the R3 contrib/ area were developed to satisfy these needs: yorn pops up a yes/no box, xmessage displays a string, etc. There are several versions of these tools; few, if any, have made it to the R4 contrib/ area, though they may still be available on various archive sites. In addition, Richard Hesketh (rlh2@ukc.ac.uk) has posted the xmenu package to comp.sources.x ("v08i008: xmenu") for 1-of-n choices. [7/90] Two versions of XPrompt have been posted to comp.sources.x, the latter being an unauthorized rewrite. [R. Forsman (thoth@reef.cis.ufl.edu), 1/91] There is a version of XMenu available from comp.sources.x; it is being worked on and will likely be re-released. xp-1.1.tar.Z, xpick-1.0.tar.Z and xzap-1.0.tar.Z on export's contrib/ are tools by Gerry.Tomlinson@newcastle.ac.UK which act as X versions of the simple display and choice-making tools in K&P. [4/92] xtpanel lets the user build a panel containing interactive objects such as buttons, sliders, text fields, etc., either from the command line or using a simple scripting language. It is available for anonymous ftp from hanauma.Stanford.EDU (36.51.0.16) as pub/X/xtpanel.tar.Z and may also be found in the alt.sources archives. ---------------------------------------------------------------------- Subject: 90)! Where can I get an X-based debugger? xdbx, an X interface to the dbx debugger, is available via ftp from export. The current [1/91] version is 2.1 patchlevel 2. An X interface to gdb called xxgdb is more like xdbx 2.1.2. It is part of comp.sources.x volume 11 [2/91]. mxgdb is a Motif interface to gdb by Jim Tsillas (jtsillas@bubba.ma30.bull.com); version 1.1.3 was posted to alt.sources 2/92. Previous versions are on export. UPS is a source-level debugger which runs under the X11 and SunView window systems on Sun and DEC platforms. It is available from export (18.24.0.11) as contrib/ups-2.45.tar.Z and unix.hensa.ac.uk (129.12.21.7) in /pub/misc/unix/ups (or try mail to archive@unix.hensa.ac.uk). [10/92] Unofficial fixes by Rod Armstrong (rod@sj.ate.slb.com) are on unix.hensa.ac.uk in /misc/unix/ups/contrib/rod@sj.ate.slb.com. Also: MIPS produces a highly-customizable (WCL-based) Visual Debugger. You should be able to use Sun's dbxtool with its X11/NeWS server. The CodeCenter (617-498-3000) source-level debugger, available on most major platforms, includes an X-based interface. AT&T offers the eXamine Graphical Interface, an X11 interface to dbx and C++ dbx for Sun3 and Sun4 and sdb and sdb++ for 386 and 3B2 platforms. Call 1-508-960-1997 or contact examine@mvuxi.att.com for more information. Solbourne (+1 303-678-4626) offers PDB, its X-based debugger for C, C++ and Fortran. PDB uses the OI toolkit and runs in either Open Look or Motif mode. SCO (info@sco.com) offers dbXtra as part of several development systems. ---------------------------------------------------------------------- Subject: 91) How can I "tee" an X program identically to several displays? There are several protocol multiplexer tools which provide for the simultaneous display of X clients on any number of machines. XMX (an X Protocol Multiplexor) is available from wilma.cs.brown.edu (128.148.31.66) as pub/xmx.tar.Z It works independently of the server and does not affect the application being shared; it was developed for use in the electronic classroom. XTV is a conference program which can be used to duplicate the "chalkboard" on several displays. Release 1 is available on the X11R5 contrib tapes; a more recent version is on ftp.cs.odu.edu as pub/wahab/XTV.r2.tar.Z. SHX from Michael Altenhofen of Digital Equipment GmbH CEC Karlsruhe also does this; it is a "WYSIWIS" (What You See Is What I See) package in the context of a computer-based learning/training tool to provide online help from remote tutors but is also useful for general window sharing. Information: shX@nestvx.enet.dec.com. SHX can be found on export and gatekeeper.dec.com:/pub/X11/contrib/shX.tar.Z, crl.dec.com:/pub/X11/contrib/shX.tar.Z Modifications to SHX for color mapping and private color allocation by Mark J. Handley (M.Handley@cs.ucl.ac.uk) are on cs.ucl.ac.uk in car/shX.car.tar.Z. XTrap is implemented as a server/library extension and can be used to record and then replay an x session. It is available as: gatekeeper.dec.com pub/X11/contrib/XTrap_v31.tar.Z export.lcs.mit.edu contrib/XTrap_v31.tar.Z wscrawl can be used as a "multi-person paint program". It's available on sax.stanford.edu as wscrawl.shar.Z. Shdr implements a simple shared whiteboard, without a chalk-passing mechanism. It's available on parcftp.xerox.com as pub/europarc/shdr.tar.Z. Also of use: Hewlett-Packard Co. has a commercial product, "HP SharedX" which works under HP-UX currently on their 300, 400, and 700 series workstations and their HP 700/RX X Stations. Machines receiving shared windows can be any X server. HP SharedX consists of a server extensions and a Motif based user interface process. Contact your local HP sales rep. for more information. IBM offers a commercial product. Sun offers multi-user confering software called ShowMe. InSoft (Mechanicsburg, PA, USA) offers multi-user confering software called Communique.

This FAQ includes information on a number of "gotchas" that can bite you on particular system. However, the best source of general information on building the X11 release is found in the Release Notes. The file is bundled separately from the rest of the release, so if it's become separated from your sources you can FTP another copy separately: the file RELNOTES.[ms,PS,TXT] at the top of the distribution. The file RELNOTES is also available from the xstuff mail server. In addition, O'Reilly & Associates's Volume 8 on X Administration includes information on configuring and building X. ---------------------------------------------------------------------- Subject: 94) Why doesn't my Sun with a cg6 work with R5? Apparently gcc is the problem; it seems to produce fine code for all Sun displays except for the cgsix. The new sunGX.o distributed with fix-07 may fix the problem (note: not known to work on Solaris). ---------------------------------------------------------------------- Subject: 95) Why doesn't my Sun with SunOS 4.1 know about _dlsym, etc.? If you get errors with _dlsym _dlopen _dlclose undefined, link with libdl.a. Add "-ldl" to your and eventually your site.def. You may want to surround it with "-Bstatic -ldl -Bdynamic" if you add it to the EXTRA_LIBRARIES variable, since "syslibs" get added after EXTRA_LIBRARIES on the eventual compilation command; otherwise you may not have a shared libdl. (Or compile the stubs shared.) [thanks to Joe Backo (joe.backo@East.Sun.COM), 12/91] ---------------------------------------------------------------------- Subject: 96)! What is this strange problem building X clients on SunOS 4.1.2? In SunOS 4.1.2 Sun fixed a shared-library bug in ld which conflicts with the way X11R4 builds the shared Xmu library, causing these symbols to be undefined when building some X11 clients: _get_wmShellWidgetClass _get_applicationShellWidgetClass Compiling "-Bstatic -lXmu -Bdynamic" appears to work. To solve the problem if you are using OpenWindows 3.0 (X11R4-based Xt), please contact your local Sun office and request the following patches: Patch i.d. Description 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch 100573-03 4.1.x OpenWindows 3.0 undefined symbols when using shared libXmu [Greg Earle, earle@Sun.COM; 7/92] A source patch for use with the MIT X11R4 libraries was developed by Conrad Kimball (cek@sdc.boeing.com); it retrofits into R4 some fixes made in R5 to get around this problem. The patch is on export in [1/93] contrib/X11R4_sunos4.1.2_patch_version3.Z ---------------------------------------------------------------------- Subject: 97) Why can't gcc compile X11R4 on my SPARC? I used gcc to compile the whole distribution, but I get several segmentation faults when running X. Note first that gcc on RISC machines does not necessarily result in any performance increase; it certainly is not as noticeable as it is on the 680x0 or VAX platforms. Here is the problem: gcc and cc use incompatible methods of passing structures as arguments and returning them as function values, so when gcc-compiled parts of X are linked with Sun-supplied functions that pass or return structs, run-time errors occur. Affected programs include rgb and the server. This is from the GCC manual: On the Sparc, GNU CC uses an incompatible calling convention for structures. It passes them by including their contents in the argument list, whereas the standard compiler passes them effectively by reference. This really ought to be fixed, but such calling conventions are not yet supported in GNU CC, so it isn't straightforward to fix it. The convention for structure returning is also incompatible, and `-fpcc-struct-return' does not help. You can duck the problem either by using cc throughout or by using it for just the routines which cause incompatibilities; the problem cannot be solved with compilation flags. Files which need to be compiled using cc include: server/os/4.2bsd/oscolor.c rgb/rgb.c In addition, several of the "inet_" functions use structs as args or return values: clients/xhost/xhost.c clients/xauth/gethost.c. Calls to inet_addr in /lib/CLX/socket.c and lib/X/XConnDis.c are possibly harmless as they don't involve structs. [collected by bashford@scripps.edu (Don Bashford); 8/90] ---------------------------------------------------------------------- Subject: 98) What are these I/O errors running X built with gcc? When I try to run xinit or the Xsun server I get the error "Getting interface configuration: Operation not supported on socket. Fatal server bug! no screens found." Running the gcc fixincludes script apparently didn't work. You can do this simple test: #include <sys/ioctl.h> SIOCGIFCONF Run that through cc -E and gcc -E. The last line of output is the piece of interest; it should be identical (modulo irrelevant differences like whitespace). If the gcc version has 'x' where the cc version has 'i', your fixincludes run didn't work for some reason or other; go back to your gcc sources and run `fixincludes`; then rebuild the X distribution. If they are identical, try running a make clean in mit/server and rebuilding, just to make sure everything gets compiled with the proper include files. [courtesy der Mouse, mouse@LARRY.MCRCIM.MCGILL.EDU; 9/90] ---------------------------------------------------------------------- Subject: 99) What are these problems compiling X11R4 on the older Sun3? In mit/server/ddx/sun/sunCG3C.c, we have found "missing" defines for CG3AC_MONOLEN, CG3BC_MONOLEN, CG3AC_ENBLEN, CG3BC_ENBLEN. What should these be? The R4 Errata list distributed after X11R4 mentions that you can add these lines to the file on older SunOS versions (e.g. 3.5) to compile: #define CG3AC_MONOLEN (128*1024) #define CG3AC_ENBLEN CG3AC_MONOLEN #define CG3BC_MONOLEN CG3AC_MONOLEN #define CG3BC_ENBLEN CG3AC_MONOLEN However, the Sun3 should not actually ever have the CG3 device, and so references to it can be removed from mit/server/ddx/sun/sunInit.c and the Imakefile. [11/90] ---------------------------------------------------------------------- Subject: 100) What are these problems compiling the X server on SunOS 4.1.1? The file <sundev/cg6reg.h> isn't being found. Sun omitted <sundev/cg6reg.h> from SunOS 4.1.1. Remove the #include from sunCG6C.c and replace it with the line #define CG6_VADDR_COLOR 0x70016000 The file has changed from earlier versions of SunOS and should not be copied from another distribution. ---------------------------------------------------------------------- Subject: 101) What are these problems using R4 shared libraries on SunOS 4? All of the executables that I try to run have the following results: ld.so: libXmu.so.4: not found or even: ld.so: call to undefined procedure __GetHostname from 0xf776a96c If you are building with shared libraries on a Sun, remember that you need to run "ldconfig" as root after installing the shared libraries (if you've installed X on a file-server, run it on the server's clients, too). While building and installing the distribution, you need to be careful to avoid linking against any existing X shared libraries you might have (e.g. those distributed with OpenWindows). You should make sure you do not have LD_LIBRARY_PATH set in your environment during the build or the installation. If you are going to keep xterm and xload as setuid programs, please note that the shared libraries must be installed in /usr/lib, /usr/local/lib, or /usr/5lib for these programs to work (or else those programs must be linked statically). [courtesy MIT X Consortium] Note also that the program mkfontdir is run as part of the build; it attempts, however, to use the shared libraries before they have been installed. You can avoid the errors by building mkfontdir statically (pass -Bstatic to most C compilers). ---------------------------------------------------------------------- Subject: 102) Can OLIT programs run with R5 Xt? (_XtQString undefined) This is a bug in the OLIT. _XtQString was an external symbol that existed in X11R4 (upon which OW 3.0's libXt is based). It wasn't documented and was removed in X11R5 (MIT's guarantee of upward compatibility between the R4 and R5 libraries only applied to the documented interface). A workaround is to temporarily set your LD_LIBRARY_PATH to point to the X11R5 Xt library that you linked the program against. [10/92; from Barry Margolin (barmar@think.com) ---------------------------------------------------------------------- Subject: 103) How do I get around the SunOS 4.1 security hole? There is a security problem with certain R4 clients (xterm and xload) running under SunOS 4.1 that have been installed setuid root and are using shared libraries; to avoid the problem, do one of these: 1) make the program non-setuid. You should consult your system administrator concerning protection of resources (e.g. ptys and /dev/kmem) used by these programs, to make sure that you do not create additional security problems at your site. 2) relink the programs statically (using -Bstatic). 3) install the libraries before linking and link with absolute paths to the libraries. [from rws@expo.lcs.mit.edu (Bob Scheifler), 12/90] The R5 version of xterm does this automatically by rebuilding xterm against the newly-installed libraries when xterm is being installed; this prevents an suid program from being built with libraries specified relatively. Note that this may cause an inconvenience when doing the installation from NFS-mounted disks. Xload has been rewritten to avoid the problem. ---------------------------------------------------------------------- Subject: 104) TOPIC: BUILDING X PROGRAMS ---------------------------------------------------------------------- Subject: 105) What is Imake? Imake is not a replacement for the make program; instead, it is a makefile-generator that takes advantages of the include-file and macro- processing capabilities of the C preprocessor cpp to generate makefiles suitable for building software on a particular system. Although it is not specific to X, the X release uses it to help solve a number of the configuration issues that arise in making such a large system widely portable. Imake has a fairly steep learning curve, in part because the process by which the system-specific configuration files, system-independent configuration files, and individual Imakefiles are melded to produce a Makefile is not obvious. There have been several different versions of imake; the R3, R4, and R5 versions are different. You can obtain information on imake from these sources: - the R4 and R5 release notes and imake man page include information on using Imake to build X - the R4 and R5 file mit/config/README also contains useful information - on the R4 tapes, contrib/doc/imake/imake.tex is Mark Moraes' R3/R4 guide to imake. - the R5 mit/doc/config/usenixws/paper.ms contains a paper by Jim Fulton on an early version of Imake - Paul Dubois (dubois@primate.wisc.edu) has written a useful explanation of how Imake works and how to use it in configuring X for non- supported systems; the document is available from ftp.primate.wisc.edu in the directory ~ftp/pub/imake-stuff; look for config-X11R4.ms (troff) and config-X11R4.ps (PostScript). Some supplemental appendices are nearby. [7/91: document version is now 1.06] - see "System Administration - Imake: Friend of Foe?" by Dinah McNutt in the November 1991 issue of SunExpert. - German readers should expect in June 1992 an article "Das Meta-Make / I make, you make / Schwerelos" by Rainer Klute in "iX Multiuser-Multitasking-Magazin", directed at application programmers needing to write Imakefiles. An English-language derivative of this article is in The X Journal, issue 2:1. - The O'Reilly X Resource issue #2 contains Paul Davey's article on demystifying Imake. - Alain Brossard's working document full of tips on Imake is in sasun1.epfl.ch:pub/imakefile.1.Z. [1/91;12/91;5/92;8/92] ---------------------------------------------------------------------- Subject: 106) Where can I get imake? Versions are distributed with the R4 and R5 releases. An earlier version is distributed with the X11R3 release; some third-party toolkits redistribute versions of imake along with their own implementations of the template and configuration files. There are no real standards for such configuration files, although most *current* contributed software expects the templates distributed with X11R5. export contains the R5 distribution unpacked, so you can pick up imake without picking up the entire distribution. A stand-alone version of Imake, but one stemming from X11R5, is in ftp.germany.eu.net:pub/X11/misc/imake/imake-pure.tar.Z (192.76.144.75). ---------------------------------------------------------------------- Subject: 107) I have a program with an Imakefile but no Makefile. What to do? If you have R4 or R5 installed on your system, run "xmkmf". This is a script which runs imake for you with the correct arguments. The output is a Makefile configured for your system and based on the Imakefile. Then run make, which will use that new Makefile to compile the program. ---------------------------------------------------------------------- Subject: 108) Why can't I link to the Xlib shape routines? When I try to compile certain programs, I get the following link error: Undefined: _XShapeQueryExtension _XShapeCombineMask These routines are actually part of the Shape Extension to X (SHAPE) which was introduced in the MIT X11R4 distribution and allows non-rectangular windows. Like the other sample server extensions, the shape extension will only run on a server which supports it. Pre-X11R4 servers, as well as many vendor-supplied servers, do not support the shape extension, in which case they will display rectangular windows anyway. In order to use the shape extension, you must link to the library libXext.a. In the X11R4 distribution, this library and the associated includes will be in the mit/extensions directory. If you do not have these files, do not despair: many freeware programs which use the shape extension can also be compiled without it by removing the -DSHAPE define from the Makefile; you can probably do this and compile successfully against your older vendor-supplied X libraries. [from John B. Melby, melby%yk.fujitsu.co.jp@uunet.uu.net, 3/91] ---------------------------------------------------------------------- Subject: 109) What are these problems with "_XtInherit not found" on the Sun? When I run a X program that I wrote on a SunOS 4.0.3 or 4.1 machine I get the error "ld.so: symbol not found _XtInherit". What you are seeing is a side-effect of a kludge in the R4 libXt.a to get Sun shared libraries working. Apparently, you can't share a function that is both called and compared, as _XtInherit is. This was handled by putting _XtInherit in the same file as a function that is always used, thereby guaranteeing that it would be loaded -- that is, in Initialize.c, where XtToolkitInitialize() and XtInitialize() reside. These routines would normally be called. You are probably seeing this error because your program is not a normal Xt-based program and does not call XtToolkitInitialize() anywhere. 1) it may be a program that uses Xt functions but never opens a connection to the X server. [OSF/Motif's 1.1.0 UIL had this problem; it called XtMalloc() and other Xt functions.] The solution is to add the call to your program; the function does not have to be executed, just linked in. 2) alternatively, your program doesn't need any Xt functions and is correct in not calling XtToolkitInitialize() -- it may be an Xlib or XView program. In this case, you can remove -lXt from your link command. It should not be necessary to link the shared libraries statically, although this will certainly solve the problem. [from Jordan Hayes (now jordan@MooreNet.COM) and Danny Backx (db@sunbim.be); 11/90] ---------------------------------------------------------------------- Subject: 110) Why can't I compile my R3 Xaw contrib programs under the new X? I have a program that worked well under X11R3. When I try to link it under the current version of X, I get this message: Undefined: _XtScrollBarSetThumb _XtTextSetInsertionPoint _XtTextReplace There were several name changes in the Athena widget set (in addition to the header files moving into <X11/Xaw/>); these are mentioned in the R4 release notes. In this case, these functions are not really Xt functions but are part of the Xaw text widget and so have been renamed from Xt* to Xaw*. [10/90] ---------------------------------------------------------------------- Subject: 111) TOPIC: PROGRAMMING PROBLEMS AND PUZZLES ---------------------------------------------------------------------- Subject: 112) Why doesn't my program get the keystrokes I select for (sic)? The window manager controls how the input focus is transferred from one window to another. In order to get keystrokes, your program must ask the window manager for the input focus. To do this, you must set up what are called "hints" for the window manager. If your applications is Xlib-based, you can use something like the following: XWMHints wmhints; ... wmhints.flags = InputHint; wmhints.input = True; XSetWMHints(dpy, window, &wmhints) If your application is based on the Xt Intrinsics, you can set the XtNinput resource to be True (as you probably want to in any case); if you don't have source, you can start up the application with the resource '*input:True'. Certain window managers, notably dxwm and olwm, are very picky about having this done. If you are using Sun's OpenWindows olwm, you can also add this resource to your defaults file to use clients that aren't ICCCM-compliant. OpenWindows.FocusLenience: true [mostly courtesy Dave Lemke of NCD and Stuart Marks of Sun] ---------------------------------------------------------------------- Subject: 113) How do I figure out what window manager is running? You can't reliably tell; whatever mechanism you could use could be spoofed in any case. For most cases, you shouldn't care which window manager is running, so long as you do things in an ICCCM-conformant manner. There are some cases in which particular window managers are known to do things wrong; checking for particular hints placed on the window by the window manager so that you can sidestep the problem may be appropriate in these cases. Alternatively, it may be appropriate to determine which window manager is running in order to take advantage of specific *added* features (such as olwm's push-pin menus) in order to give your program *added* functionality. Beware of usurping the window manager's functions by providing that functionality even when it is missing; this surely leads to future compatibility problems. ---------------------------------------------------------------------- Subject: 114) Is there a skeleton X program available? There is no general framework such as the TransSkel program for the Macintosh which handles lots of the odds and ends and overhead of development under a window system and which can be used as a platform for additional development. In X, the problem is typically solved by using an interactive application builder tool or by using cut&paste on existing X applications. Good applications which you might look to manipulate when you want to "test just this one little thing" include contrib/clients/xskel, a simple R4 program that puts up a window and allows sketching in it and offers a starting point for quick hacks, the Xaw examples in the examples/ directory in the R3 and R4 distributions, and the Xlib "Hello World" example in the R3 doc/HelloWorld and R4 doc/tutorials/HelloWorld; an updated version of this program which uses R4 Xlib calls and current ICCCM conventions was posted in 2/90 to comp.windows.x by Glenn Widener of Tektronix. [3/90] In addition, a sample Xt program (for Xaw or Xm) by Rainer Klute showing how to open multiple displays and how to catch a broken display connection is available on export.lcs.mit.edu in contrib/mdisp.tar.Z.
