I read the rules at the registration process.
This posting was not about ...
1. a programming issue.
2. a compiler/linker error.
3. being too lazy to search Google or this forum.
I believed it was a Code::Blocks manipulation problem from my side, id est me making a mistake inside the Code::Blocks GUI in order to link a library. So I was asking for help in doing that, and not asking for general programming / compiler / linker help.
Sorry if what I tried was not possible, but I simply followed the stackoverflow article (I linked in OP), which didn't work for me.
FYI: You can NOT statically link an dynamic library; IIRC, the ".so" means dynamic library on Linux!
Thanks for the info!
