Only one tqt.pc found. ld.so.conf was messed up, however, probably from so much experimenting. > Assuming you don't find a stale tqt.pc file there are a few > options open > to you: > 1.)

Well here is an interesting turn of events. I added the following to my ugly script function hack: pkg-config --cflags-only-I tqt The command returns no results. When directly in a terminal the command returns the expected -I/usr/lib/qt3/include -I/usr/include/tqt. So perhaps the problem is right there. For whatever reason pkg-config is not running from within scripts. Or is dumping the results to the bit bucket. Anybody have ideas why? I haven't yet found anything on the web. Darrell
