oga@ and jsg@ pointed me to byacc - thanks! There is some yacc specific constructs in cwm's parser that bison doesn't support. To address the mail from [EMAIL PROTECTED]: I think this _is_ OpenBSD related (opposed to Linux related), as there might be other OpenBSD users, like me, who want to use cwm on their non-OpenBSD boxes as well, and Linux-only users hardly know about the cwm in OpenBSD. The following is an attempt to make a simple guide. OpenBSD's cwm window manager on Ubuntu Linux -------------------------------------------- 1. Install the following packages: byacc libxext-dev libexpat1-dev libxft-dev libfontconfig1-dev libxrender-dev libxau-dev xlibs-dev libxdmcp-dev zlib1g-dev You might also need to install cvs and xterm (xterm is the default terminal for cwm to start when one types ctrl+alt+enter). 2. Pick an anonymous CVS server close to you: http://www.openbsd.org/anoncvs.html#CVSROOT 3. Checkout cwm as of July 24, 2008: $ export CVSROOT=(what you picked in step 2) $ cvs -q -d$CVSROOT checkout -D 2008-07-24 xenocara/app/cwm U xenocara/app/cwm/LICENSE U xenocara/app/cwm/Makefile [..] U xenocara/app/cwm/xmalloc.c U xenocara/app/cwm/xutil.c $ cd xenocara/app/cwm 4. Patch the source using cwm-linux.patch (attached inline further down): $ patch < cwm-linux.patch patching file calmwm.c patching file calmwm.h patching file conf.c patching file headers.h patching file kbfunc.c patching file parse.y 5. Generate the parser using byacc: $ byacc -d parse.y $ mv y.tab.c parse.c 6. Compile and link: $ for i in *.c; do gcc -I /usr/include/freetype2 -c $i; done $ gcc -lXft -lXrender -lX11 -lXau -lXdmcp -lXext -lfontconfig -lexpat -lfreetype -lz -o cwm *.o 7.
