Explicit is better here.
Well, of course I was assuming that your link line would add "-L." or similar so that you know that the local directory is always searched first. 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. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
