Building a cross-gdb with host=i686-pc-linux-gnu and target=powerpc-apple-darwin

Building a cross-gdb with host=i686-pc-linux-gnu and target=powerpc-apple-darwin

[Gregor Riepl]

Hi, this is my first posting here.

How can I build a cross-gcc on my Linux box (host=i686-pc-linux-gnu) for 
kernel debugging on my iBook G4 running Mac OS X 10.3.4? Apple doesn't cover 
this issue in their docs and I couldn't find any decent cross-gdb information 
on the net.
I tried to use gdb-5.3 with a more recent libbfd (the included one doesn't 
know about Darwin), but this gives me a gdb that doesn't understand Mach-O:
"I'm sorry, Dave, I can't do that.  Symbol format `mach-o-be' unknown."
gdb-6.3 builds, but I don't get a gdb, only a few support libs.
I also tried Apple's gdb-309, which seems to need Darwin headers.
Maybe I can get it to work if I just copy those over.

Has someone tried this?
gdb should easily do the job, but I had no luck yet.
Thanks for your help!

Gregor

There's no Darwin support in GDB outside of Apple's sources, so you're
out of luck asking here.  Might want to try an Apple list instead.

They couldn't help much either, but I was able to adapt Apple's gdb to build 
on GNU/Linux.
So, if someone's interested, please have a look at my homepage:
