Thread: How do I make shared libs on Linux?

Thanks, that did it.

BTW, do you know when it's necessary to use the -shared flag?
I'm still using it for building the .so library. Should I remove it there too?

-shared is how .so libraries are created. So yes, it's necessary there. You don't need it elsewhere.

Also remember that shared library code must be compiled with -fpic or -fPIC.

Great. and the -Bdynamic flag for ld? Is that useful, or does -shared already imply that?
