This is : obvious if you run nm(1) on libbar.so of the example above, because the : libfoo_init() function is listed as 'T'. I think that's what you want : by making the libfoo.a library non-shared in the first place. Got it! I recalled something des or phk wrote me a while ago, then I skimmed the manpage again. I have to put the .a files AFTER the object files where the unresolved symbol is found. Jonathon McKitrick -- Hoppiness is a good beer.
