Even that will typically prefer ./libfoo.so over ./libfoo.a unless you're also using -static or similar. > I don't have time to check it to be sure, but I have a vague memory that > "-lfoo" and "libfoo.a" are not equivalent to the linker: for the former > the linker only pulls in objects which contain symbols that are actually > needed, while in the latter the link unconditionally pulls in all the > objects in the library. But I could be imagining this. I've never heard of this and it's certainly not the case that writing libfoo.a pulls in unreferenced symbols with default linker options. Normally that is achieved by -Wl,-whole-archive libfoo.a -Wl,-no-whole-archive
