M. dos Santos - casantos@cpmet.ufpel.tche.br - - ------------------------------------------------------------------------ - -1. Introduction - -This directory contains the source code for SGI's OpenGL Xt/Motif(TM) -widgets, slightly modified to generate both Motif 1.x and 2.x versions of -the widget even if Motif is not available, as in the XFree86 distribution of -the X Window System. This code is based on that distributed by Silicon -Graphics as part of it's OpenGL Sample Implementation, not on the modified -version distributed with Mesa. - -2. Installation - -This code is intended to be compiled as part of the normal XFree86 building -process, under the xc/lib/GLw directory. To compile the library out of the X -source tree, follow instructions below. - -2.1. Requirements - -Gzip and tar are needed to extract the files from the distribution archive. -Tar is a standard UNIX utility but if you don't have it use GNU tar, -available in source form at ftp://ftp.gnu.org/pub/gnu/. Gzip is not a -standard UNIX utility, though available in many systems. You may obtain it -(also source form) at the same FTP server as GNU tar. - -You need xmkmf and imake too. Depending on your operating system you may -need to install some kind of X Window System development kit, so check the -vendor documentation first. I was told that some UNIX systems don't have -imake: report this as a bug (to your vendor, not me). - -Of course you will need a C compiler. - -2.2. Steps - - 1. Extract the source code from the distribution archive. - - gzip -dc GLw.tar.gz | tar xf - - - 2. Go to the surce code directory and generate the makefile. - - cd GLw - xmkmf - - For LessTif, use "mxmkmf" instead of "xmkmf". Imake support is much - better in recent versions of LessTif (since late july 2000). If your - Motif or OpenGL libraries and/or include files are installed in - non-standard locations (some UNIX vendors seem to be very creative :-) - then edit the file named Imakefile, remove the leading XCOMM of the - lines containing MOTIF_INCLUDES and MOTIF_LDFLAGS and set the - appropriate values. - - 3. Compile the code with - - make includes - make standalone - - 4. Install the library and manual pages with - - make install - make install.man - - 5. Optionally, you may compile two test programs: xmdemo and xtdemo. You - need OpenGL (or Mesa) for both and Motif (or LessTif) for xmdemo. There - are four extra make targers for these programs: demos, stand-demos, - stand-xmdemo and stand-xtdemo. You may use them with: - - make stand-demos - ./xmdemo ./xtdemo - -2.3. Creating a shared library - -By default only a static library is created because most of the UNIX -loaders, if not all, complain about unresolved symbols even if the -application doesn't use the modules in which such symbols are referenced. -However, if your system supports libraries with weak symbols (e.g. Solaris, -FreeBSD and Linux) it is possible to fool the loader. All you have to do is -edit the Imakefile, changing "#define SharedLibGLw" and "#define -GLwUseXmStubs" to YES, then repeat the compilation process starting from -step 2 in the previous section. - -2.4. Problems - -If you have trouble, ask for help in the XFree86 "xperts" mailing list. Look -at http://www.xfree86.org for instructions on how to subscribe. In -desperation, send an email to casantos@cpmet.ufpel.tche.br. - -PLEASE DO NOT SEND ME EMAIL ASKING HOW TO INSTALL OR CONFIGURE YOUR -OPERATING SYSTEM, MODEM, NETWORK CARD, BREAD TOASTER, COFEE MAKER OR -WHATEVER ELSE! - -3.

Kilgard for making their -software free. - -5. No thanks - - THIS SECTION CONTAINS MY PERSONAL OPINIONS AND DOESN'T REPRESENT - AN OFFICIAL POSITION OF THE XFree86 PROJECT. - -The first incarnation of this version of libGLw used eight header files from -LessTif, four for each Motif version. LessTif is covered by the GNU Library -General Public License (LGPL) whose terms are not compatible with the -XFree86 licensing policy. Since the copyright holder of LessTif is the Free -Software Foundation (FSF), I asked Richard Stallman, president of FSF and so -called "leader of the Free Software movement", permission to redistribute a -copy of those eight headers under XFree86 terms, still maintaining the FSF -copyright. - -Observe that I was not asking him to change the license of LessTif as a -whole, but only to allow me to distribute copies of some header files -containing function prototypes, variable declarations and data type -definitions. Even so, Stallman said no because the files contained "more -than 6000 lines of code". Which code? The LessTif headers are mostly copies -of the Motif ones and don't contain any original GNU "code"! I can't still -imagine a reason for Stallman's negative answer except for paranoia. He -seems to ignore what Motif is and that LessTif's API is simply a copy of -Motif's one. - -After spending some time, I made my own headers, that became much smaller -than the previous ones because I included only a subset of the Motif API and -merged everything into four files: 417 lines instead 6000. Humm, perhaps I -should be grateful to Sallman too :-). - -6.
