#9620 — colorForth on Linux

Hi,

the Linux ports of colorForth don't seem to be actively maintained
currently, so I thought I'd post about my experience here.  The
XcolorForth/GLcolorForth ports were done by Mark Slicker, whose website
seems to have fallen victim to bit-rot.  The only copies I can find are
those hosted by Tim Neitz [1] or by the ForthFreak wiki [2].

These distributions come with a shell script 'compile' for compilation.
To build on 64-bit Linux systems (amd64), that script needs some fixes.
You also need to install the required 32-bit libraries and GCC multilib
support (on debian try '
sudo apt-get install ia32-libs-dev ia32-libs-gtk gcc-multilib')

Here's the fixed GLcolorForth/compile script:

--8<--
#!/bin/bash
gcc -m32 -g -o glcf main.c mem.s -L /usr/X11R6/lib -lGL -lX11
gcc -m32 -c -o color.o color.s
if test -a color.o; then
cp color.com blocks
ld -m elf_i386  --oformat binary -Ttext `nm glcf | awk '/ xcf$/ {print "0x" $1}'` -o color.com color.o
dd if=blocks of=color.com bs=1024 seek=12 skip=12
rm blocks color.o
fi
--8<--

the resulting 'glcf' executable looks like running properly, but I
didn't yet find out how to operate it.

The same changes applied to XcolorForth's compile script make it
compile; however execution fails after printing 'init kbd.' twice,
without any windows opened.  Probably the video mode is just not
supported here?

cheers,

David

Short addition: not only does the 'compile' script of GLcolorForth need
some fixing; also the keyboard input handling code does not work
properly on my Debian Squeeze system: keyboard events take many seconds
to be delivered.  This short patch to 'main.c' fixes the problem here:

For now I've put a fixed version on my SVN server:
http://mosquito.dyndns.tv/freesvn/trunk/forth/glcolorforth/ , but might
eventually move everything to sourceforge.

cheers,

Hello,

Your right that this code is no longer maintained, I don't use it
anymore and I just check this group now and then to see there are any
new developments in Forth. I wasn't really an expert with this
Xwindows stuff so maybe it wasn't done properly, it was just a quick
hack to get colorForth running under Linux/Xwindows and allow more
people to try it. Hope you found it useful and feel free to improve
it.

Best,
Mark

Hi Mark,

nice that you stopped by here.  Didn't have much time yet to play around
with colorForth, and reading through the (mostly assembler) sources
wasn't very motivating :) (what a mess).  Quite remarkable how you got
it run on Linux (must have been fun patching those x86 hex-code macros
in the first colorForth blocks, that cannot even be read and edited with
any standard editor :)

While you're around, could you please clarify the copyright on the files
you added?  colorForth itself is public domain; but as it stands the
GLcolorForth is currently not (at least not legally) re-distributable.
A statement that your changes are (L)GPLv2/3, BSD public-domain
etc. would just do, I guess.  For now my copy is hosted on a private SVN
server [1], but I plan to move it to sourceforge/github/whatever.

cheers,

David

Looking at the code again, it is somewhat remarkable, maybe that I had
the patience for that :) I also had wrote some code to translate the
assembler code from MS assembly to GNU assembly.

Normally I would place my public code under GPL, but since colorForth
is public domain and there nothing too original in the GL/Xwindows
boilerplate I place all this additional code in the public domain.

Best,
Mark
