I am attempting to cross-compile libunwind for a mips64 architecture and a linux 2.6, using the following compiler (no choice there):
mips64-nlm-linux-gcc (GCC) 4.4.5 20100516 (prerelease)

The configure log is attached. I tried the following 2 commands, without any luck:

./configure --host=mips CC="mips64-nlm-linux-gcc -march=xlp -mabi=64 -mplt -msym32 -Wl,-rpath=/lib64" CPP="mips64-nlm-linux-gcc -march=xlp -mabi=64 -mplt -msym32 -Wl,-rpath=/lib64 -E"

./configure --build=mips64-linux-gnu --host=mips CC="mips64-nlm-linux-gcc -march=xlp -mabi=64 -mplt -msym32 -Wl,-rpath=/lib64" CPP="mips64-nlm-linux-gcc -march=xlp -mabi=64 -mplt -msym32 -Wl,-rpath=/lib64 -E"

When I make the library, I am encountering 2 issues:

1. PATH_MAX is not defined. I defined it locally for each of the files using it, and set it to 1024.
2. A link error, which I don't know how to resolve:

Your assistance with resolving this is much appreciated.

Thanks,
