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
