The error message is:
/usr/bin/ld: skipping incompatible /usr/local/cuda/lib/libcufft.so when searching for -lcufft /usr/bin/ld: cannot find -lcufft collect2: ld returned 1 exit status
I don’t think my -lcufft parameter in compiling a .cu file is pointing to the correct library location. I believe its pointing to the 32bit version of the libraries while trying to compile for a 64-bit machine. I’m attempting to do this on an Ubuntu 9.10 64-bit system with gcc 4.4.1.
