Hello everyone, Im trying to compile my program, but it gives this error. I’m using pg90 and mpif90.  
Can someone help me to solve it please ?

/clusterfs/pgi/Linux\_aarch64/20.7/comm\_libs/openmpi/openmpi-3.1.5/bin/.bin/mpif90: error while loading shared libraries: libnvcpumath.so: cannot open shared object file: No such file or directory

Hi Lucci,

You’ll want to set the environment’s LD\_LIBRARY\_PATH variable to include the compiler runtime libraries. Something like:

export LD\_LIBRARY\_PATH=/clusterfs/pgi/Linux\_aarch64/20.7/compilers/lib:$LD\_LIBRARY\_PATH

Hope this helps,  
Mat
