Link error to use CUDA static library ? Link error to use CUDA static library ??

I am confused to use a static library file *.a that compiled from “nvcc” command.

I put the *.cu and *.h in the path : /home/fbg/NVIDIA_CUDA_SDK/projects/interleave_7/

, then I used the below command to produce a *.a file.

nvcc -o libCUDA_interleave_7.a CUDA_interleave_7.cu -L/home/fbg/NVIDIA_CUDA_SDK/common/lib/linux/ -L/home/fbg/NVIDIA_CUDA_SDK/lib -lcudpp -lcutil -lib --compiler-options ‘-fPIC’

It seems ok to get a *.a file, but it cause some problem when I add this *.a into other project and make the execute file.

I don’t know what’s wrong with my steps, or other notes I ignore??? :wacko:

I had a similar problem earlier but seemed to have resolved it using the following.

I made the .a file using

nvcc -lib CUDA_interleave_7.cu -o libCUDA_interleave_7.a

to link with your other project

nvcc main.cpp -L("location of your libCUDA_interleave.a) -lCUDA_interleave_7 -L /usr/local/cuda/lib -lcudart -lcuda -o output

i got that error when I didn’t link to -lcudart. hope that helps.
