From the GCC manpage: The directories searched include several standard system directories plus any that you specify with `-L'. Normally the files found this way are library files--archive files whose members are object files. The linker handles an archive file by scan- ning through it for members which define symbols that have so far been referenced but not defined. However, if the linker finds an ordinary object file rather than a library, the object file is linked in the usual fashion. The only difference between using an `-l' option and specifying a file name is that `-l' surrounds library with `lib' and `.a' and searches several directories. hence either order should work, as well as: -L/usr/local/lib/libparanoia.so --Ben -------------------------------------------------------------------- Ben Lyon blyon@blindfaith.org (415)286-0896 On Mon, 24 Jun 2002, Michael Sharp wrote: > Thx Chris, yea, I see now that it is backwards, but thats how the author > had it documented.
