Linking to a Specific Library with C

Question

I have to use the SNAP C-library.

I compiled my file snap_test.c with the following command:

gcc -fopenmp -c -I/home/myName/SNAPDIR/include snap_test.c

And then linked it with the library:

gcc -fopenmp -o snap_test -L/home/myName/SNAPDIR/lib -lsnap snap_test.o

But running the program leads to an error:

./snap_test: error while loading shared libraries: libsnap.so.0: cannot open shared object file: No such file or directory

In the lib-dir there are those dirs and files:

libsnap.a libsnap.la libsnap.so (dir) libsnap.so.0 (dir) libsnap.so.0.0.0

I guess the problem is the different versions of the libraries?!

You need to add /home/myName/SNAPDIR/lib to LD_LIBRARY_PATH.

$ export LD_LIBRARY_PATH+=:/home/myName/SNAPDIR/lib
