centos 5 not supported?

[ksong]

Hi, I am new to CULA as well as CUDA in general. When I try to download CULA, I can't find a suitable linux OS:
Linux (64-bit)
Linux (32-bit)
RHEL 4.8 (64-bit)
RHEL 4.8 (32-bit)

I have tried to downloaded both, but they have competiability issues:
$ gcc -o test -I$CULA_INC_PATH -L$CULA_LIB_PATH_32 -lcula -lcublas -lcudart test.c
/usr/bin/ld: skipping incompatible /usr/local/cula/lib/libcula.so when searching for -lcula
/usr/bin/ld: cannot find -lcula
collect2: ld returned 1 exit status

Do I miss something simple?

Thanks,

Kai

You want the plain Linux version. If you're getting the incompatible warning, then you should be using the 64-bit version rather than 32-bit. Switch to -L/usr/local/cula/lib64 and it should work.
