You need the libmydynamiclib.a file as well as the .so file and you should tell ld or gcc where to find it too.

e.g. gcc -o myapp -L/path/to/lib -lmydynamiclib

where libmydynamiclib.so lives in /path/to/lib.

Otherwise, don’t link the library, but use dlopen() to load it dynamically. See the dlopen() manpage.
