Yes, you can use any Harbour library with mod_harbour, simply modify modharbour.hbp to include your lib name
and hbmk2 will build mod_harbour with it.
Your library name ".hbx" must be specify in apache.prg to tell hbmk2 the symbols to link. hbx files are ascii files
with the names of the functions included in the lib. Please review Harbour provided hbx examples. Real simple.
That easy :-)
