Hi
found the bug - there must be some typo/bug in your build system as it
does not build the gdb/ directory at all with --target=x86_64-darwin!
I had to run configure in topdir first then after it finishes cd gdb,
then rerun same configure (--target=x86_64-darwin) in gdb dir, make,
cd .. && make install.
This worked and gives me:
l /usr/local/gdb/bin/
total 44032
drwxr-xr-x 2 root root 4096 2010-10-20 16:22 ./
drwxr-xr-x 6 root root 4096 2010-10-20 16:05 ../
-rwxr-xr-x 1 root root 17567402 2010-10-20 16:22
x86_64-apple-darwin-gdb*
-rwxr-xr-x 1 root root 17567431 2010-10-20 16:22
x86_64-apple-darwin-gdbtui*
BUT, there is another issue now. The so generated
x86_64-apple-darwin-gdb* does not recognize 64bit binaries:
(e.g. /home/exchange/ls is the binary I want to debug)
/usr/local/gdb/bin/x86_64-apple-darwin-gdb /home/exchange/ls

Setting up the environment for debugging gdb.
WHY it says:
"/home/exchange/ls": not in executable format: File format not
recognized
?
as I built for the darwin target?
file /home/exchange/ls
/home/exchange/ls: Mach-O fat file with 2 architectures
