I have these shared library files in /usr/local/lib:
libopenbabel.so
libopenbabel.so.4
libopenbabel.so.4.0.2
libopenbabel.so is actually a link to libopenbabel.so.4 and libopenbabel.so.4 is actually a link to libopenbabel.so.4.0.2
when I compile my file with this command:
g++ test.cpp -L/usr/local/lib -lopenbabel
and then try to run a.out, I get this error:
./a.out: error while loading shared libraries: libopenbabel.so.4: cannot open shared object file: No such file or directory
Implying that the compiler is finding libopenbabel.so but running into an error when following that link to libopenbabel.so.4 which is in the exact same directory. Any ideas on why this is happening / how I can fix it?

Either set your LD_LIBRARY_PATH environment variable to contain /usr/local/lib or add /usr/local/lib to /etc/ld.so.conf and run ldconfig as root.
Also, run ldd a.out to check that dynamic linking works well on your app.
