Hi Craig,
Thanks for your replies.
I'm starting to get the hang of it, but have hit a roadblock with a
fairly simple program that crashes GPAL.
Tarball attached.
Also, I'm finding that if I compile to assembler, then assemble/link,
I'm seeing combinations of:
- gpasm failing
- gplink segfaulting
Cheers
David
PS I'm glad you're committing to CVS. I tried building from CVS, but the
build failed with (errors following). Hopefully when the commits are
done, things will build ok. (BTW, I'm on Debian unstable, with 2.6.9
kernel, most other things up to date).
Making all in gpasm
