static and dynamic linking

Hello,

is it possible, with GNU toolchain, to statically relink dynamically linked binary? For instance, if i have a.out that depends on libsomething, i want to integrate libsomething into a.out.

Yes, but you will need:

the source code for the program (to be precise: actually the object file).
The static version of the lib. If you have the source, you can probably recompile the lib to static version (*.a type of lib file instead of *.so).
Relink the object file of the program with the static lib

But, are you sure you need to do this? If there is an update for the (shared version) of the lib, your program will still use the old version until it gets re-linked with the new version of the static lib. Also using static libs isless memory efficient.
