cannot open shared library during execution

I compiled my program as follows:

mpicc b_eff_io.c -o b_eff_io2 -I/scratch/irodero/papi/include -L/scratch/irodero/papi/src -lpapi -lm

However I got this error:

 error while loading shared libraries: libpapi.so: cannot open shared object file: No such file or directory

What should I do?

Maybe...

• the library is in use
• the permissions are incorrect
• it does not exist
• it's not in the library search path

I had a similar problem.

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

$locate libpapi.so
/usr/local/lib64/libpapi.so
/usr/local/lib64/libpapi.so.4
/usr/local/lib64/libpapi.so.4.1.4.0

Creating a symbolic link to /usr/lib fixed the issue

ln -s /usr/local/lib64/libpapi.so /usr/lib/libpapi.so
