Executable shared libraries

Question

Most of the time, when you compile a shared library, executing it is meaningless and doing so produces nothing useful:

$ ./libfoobarbaz.so
Segmentation fault         


        

Answer 1

There is a howto about this subject here. The principle is to define an entry point in the library and populate the interp section of the ELF file with the interpreter's pathname (e.g. /lib/ld-linux.so.2).
