/usr/bin/ld: cannot find -lmydynamiclib

I'm using most recent versions of (ubuntu 10.10 ,netbeans, eclipse)

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.

The linker can't find your shared library in it's search path. If you add the directory where your shared lib is to the LD_LIBRARY_PATH environment variable the linker should find it and be able to link against it.
