I'm trying to compile cwm (/usr/xenocara/app/cwm) on Linux, as I would
like to use this very supreme window manager on all my non-OpenBSD
systems as well. The version of cwm that I'm working with is from
yesterday's -current (23rd of July, 2008). The Linux distribution is
Ubuntu Feisty.

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:
byacclibxext-dev
libexpat1-devlibxft-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. Enjoy:
$ ls -l cwm
-rwxr-xr-x 1 mt mt 83963 2008-07-24 21:21 cwm
Corrections and flames are most welcome :-)
