Hi, for about a week ago I upgraded from RH 5.0 to 5.1. RH 5.1 seems to be stable and works fine, except from one thing that causes me trouble. The fact is that since the upgrade I can't compile programs using the QT-toolkit (http://www.troll.no/). The results when I try to build a program using QT is lots of warnings and lots of undefined references during linking. This is the result when I try to compile the simple "Hello World" example: ------------------------------- gcc -c -O2 -fno-strength-reduce -Wall -W -I/usr/X11R6/include -I/usr/lib/qt/include -o
