Error while loading shared libraries: libnvJitLink.so.12

Accelerated Computing CUDA CUDA NVCC Compiler

I am trying to compile my cuda code but this error message was shown :

./a.out: error while loading shared libraries: libnvJitLink.so.12: cannot open shared object file: No such file or directory

I have cuda 12.2 version with latest hpc toolkit installed. They both came bundled. I have installed it in a custom location instead of /opt/ .

Any help will be great for me!

Thanks and regards

You may need to set your LD_LIBRARY_PATH variable correctly. Using a file find utility, locate where libnvJitLink.so is on your system. Then set your LD_LIBRARY_PATH to include that location.

I did same just now. The output of the find utility is this:
./data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/stubs/libnvJitLink.so
./data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/libnvJitLink.so.12.2.91
./data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/libnvJitLink_static.a

I then exported it as :
export LD_LIBRARY_PATH=/data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/

Error is still same. Is there any thing I am missing?

The app is expecting libnvJitLink.so.12

For some reason that does not appear to be in your /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib directory.

What is the result of:

ls /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib

?

If you have root privilege, you could try doing:

ln -s -T /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/libnvJitLink.so.12.2.91 /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/libnvJitLink.so.12

Thank you for the response!

The result of l libnvJitLink* in that directory is :

libnvJitLink.so@     libnvJitLink.so.12.2.91*
libnvJitLink.so.12@  libnvJitLink_static.a*

what is the result of:

ldd a.out

?

You’re right, it is still unable to locate libnvJitLink.so.12
Here’s the output:

what is the result of:

ls -l /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/libnvJitLink*

and

echo $LD_LIBRARY_PATH

?

Thank you @Robert_Crovella !
When I set the LD_LIBRARY_PATH to /data/nvhpc/Linux_x86_64/23.7/cuda/12.2/targets/x86_64-linux/lib/, it worked! All other location where libnvJitLink.so.12 was located didn’t worked.
Thank you for the help!

edit: /data/nvhpc/Linux_x86_64/23.1/cuda/12.2/targets/x86_64-linux/lib/

I thought you had done that already:

11

I did same. But it worked this time. And I also tried to export all other locations of nvJitLink. Only difference between then and now is I downgraded my cuda version bundled with HPC toolkit from 23.7 to 23.1 which is bundled with cuda 12.1
