POSIX specifies some of these libraries and says that you have to link with, e.g., -lm if you use math functions. It also says that the same functions may be available without -lm. But some of these libraries are not in POSIX. dlopen, for example, should be usable without -ldl according to POSIX, but in glibc before 2.34, it is not. And yes, in glibc 2.34, there are libdl.a etc. files, so that the old -ldl etc. options still work. Thanks, Florian
