Hi, I cant get simple qt helloworld programs to compile. It complains about not being able to find qapplication.h and other header files which reside in /usr/X11R6/include on my FreeBSD 4.8 system. I have tried using the -I/usr/X11R6/include -L/usr/X11R6/lib flags when I complie with gcc or g++. Please help Rohit
