Converting .a to .so

Use the .o files inside the .a archive to create a .so

1. Extract the .a archive:

   ar x libsomething.a

   → This will extract the object (.o) files contained within.

2. Create the .so shared library (compatible up to C++11):

   g++ -shared -fPIC *.o -o libsomething.so

   Notes:

   • The -fPIC flag generates position-independent code, which is required for shared libraries. If the original .a was not compiled with -fPIC, this method may fail.
   • If there are any dependencies, link them explicitly using -l flags.
