Building a CUDA 3.0 dll wrapper, compile errors

[Seth Shelnutt]

I've done this before, with no problems for cuda 2.x, but it's been a while
and I'm having troubles. I think I have everything configured right, as I
got the cufft dll wrapper compiled but the cudart dll wrapper is acting like
I am not linking it to the linux libcudart.so, but I am. I've noticed a few
changed in winemaker, and I thought I'd get some to check my make file / see
if they can see anything wrong.

My source can be found here, http://shelnutt2.host56.com/cudart/ . I'm
assuming your cuda toolkit is installed in the default location of
/usr/local/cuda . My errors are:

To me it looks like you forgot to link to some additional cuda
libraries. Try to figure out which cuda libraries contain these
symbols. For instance 'nm -D' could help you there or less reliable a
basic grep.
