[cfe-dev] CUDA math library cannot be found error

[Hahnfeld, Jonas via cfe-dev]

Hi,

 

Assuming you are using clang-omp from GitHub (which is discontinued btw):

You have to put <CUDA_ROOT>/nvvm/libdevice into your $LIBRARY_PATH (not
$LD_LIBRARY_PATH).

Clang should then automatically find the required files.

 

Cheers,

Jonas

Subject: [cfe-dev] CUDA math library cannot be found error

 

While trying to compile my code, I got the following error:

 

clang -fopenmp -omptargets=nvptx64sm_35-nvidia-linux -g -O3 -std=c99
Source.c -o source -L /home/rjordans/openmp4/lib -lm

clang-3.8: error: CUDA math library (libdevice) is required and cannot be
found.

 

How can I solve this error?
