Appears his system > is gentoo You don't givec me really enoough for me to go on, but I think really you need to know about 3 options to gcc (at least one of which you should be using, but you aren't) -v = means for gcc (which is really a smallish driver program for the real compiler) to show all of the subprograms that it kicks off, including all of the parameters it uses, and specifically for you, it shows the entire lib and include file search path it knows aboout. You aren't using this, so far as I can see. The other two are options to add to the default search path. Above, it seems like you are using -l to add an include file path, this is wrong, you should use -I, -l is to specify specific libraries to link in, not a path to search for the libs in. To add a library search path, you use -L. ... > > Steve > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
