FreeBSD Port: qt-3.0.5_3

[Mohamed Ilane]

hello,
I have problem compiling qt programs with qt toolkit.
I install qt-3.0.5_3 coming with the FreeBSD 4.7 cdroms, i notice that:
  a.. the qt include files are in /usr/X11R6/include
  b.. the QTDIR is not defined
after adding set QTDIR = /usr/X11R6 in my .cshrc. (is this  good? )
when i execute this :
# qmake -project
# qmake
i get the error :
QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: project.pro.
i read the qt documentation and i add this line to .cshrc
set QMAKESPEC = freebsd-g++
after that i execute :
# qmake
i get the same error.
can you tell me what i'm doing wrong?
thank's.
