This is not true. Direct dependencies and the libraries needed for compiling are two different things. Unless the linker has become extremely smart, it is still necessary to specify all libraries a program needs on the command line. While it may be true that it is sufficient to be *dependent* only on imlib, it is still necessary to specify all those other implicit libraries to the linker. The linker is not smart enough to follow all dependencies that stem from linking to a library. What the linker needs is a list of all the files it needs to fixup the symbol table. It finds those in a .lib file that is present for every .so file.
