My question is about dynamic libraries and shared libraries in Linux and their differences. Is it possible to create a dynamic library by gcc? Is my following understanding from a dynamic library OK? I think a dynamic library is added to the address space of a running code in run time. If program A uses a dynamic library and in run time A references a variable(not inside the code of A), then the code of that library is added to the address space of A. If another program B has been linked with the same library dynamically and B references a variable (not inside the code of B), then the code of that library is added to the address space of B too. This concept is different with a shared library which its code is put into the memory only once and many programs use it. Is that right?
