M. dos Santos<BR>casantos@cpmet.ufpel.tche.br</P> - -<HR NOSHADE> - -<H3>1. Introduction</H3> -<P> -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. - - -<H3>2. Installation</H3> -<P> -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. - -<H3>2.1. Requirements</H3> -<P> -Gzip and tar are needed to extract the files from the distribution <A -HREF="http://www.inf.ufrgs.br/~casantos/libGLw/GLw.tar.gz">archive</A>. Tar is -a standard UNIX utility but if you don't have it use GNU tar, available in -source form at <A -HREF="ftp://ftp.gnu.org/pub/gnu/">ftp://ftp.gnu.org/pub/gnu/</A>. 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. - -<P> -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). - -<P> -Of course you will need a C compiler. - -<H3>2.2. Steps</H3> -<P> -<OL> - <LI>Extract the source code from the distribution archive. - <P> - <CODE> - gzip -dc GLw.tar.gz | tar xf - - </CODE> - <P> - <LI>Go to the surce code directory and generate the makefile. - <P> - <CODE> - cd GLw<BR> - xmkmf - </CODE> - <P>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. - <P> - <LI>Compile the code with - <P> - <CODE> - make includes<BR> - make standalone - </CODE> - <P> - <LI>Install the library and manual pages with - <P> - <CODE> - make install<BR> - make install.man - </CODE> - <P> - <LI>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: - <P> - <CODE> - make stand-demos<BR> - ./xmdemo - ./xtdemo - </CODE> -</OL> - -<H3>2.3. Creating a shared library</H3> -<P> -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. - -<H3>2.4. Problems</H3> -<P> -If you have trouble, ask for help in the XFree86 "xperts" mailing list. Look -at <A HREF="http://www.xfree86.org">http://www.xfree86.org</A> for -instructions on how to subscribe. In desperation, send an email to <A -HREF="mailto:casantos@cpmet.ufpel.tche.br">casantos@cpmet.ufpel.tche.br</A>. - -<P> -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! - - -<H3>3.

Since the -copyright holder of LessTif is the <A HREF="http://www.fsf.org/">Free Software -Foundation</A> (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. - -<P> -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. - -<P> -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 :-). - - -<H3>6.
