Cannot compile tutorial with qt

Hello,
After I got to compile OCC for Linux with g++-3, I then tried to compile tutorial with qt-3 and then qt-2. With qt-3 the compilation fail with tried to compile each file. When I went with qt-2, compilation of object files went ok, but it failed when trying to link all the object files into binary. Numerous errors are displayed, such as shown below.
I would be grateful if anyone could suggest or point out what I could do to get it to work. Or if anyone has a binary version of the tutorial for Linux I could tried runing.

Thank you much,
Author

Did you call the ./configure scripts ? They turn out a useful Makefile, that you can call via "make" afterwards, and it should work fine.

Maybe, you should check again all compiler-flags and the included Libraries "-I..." for you gcc-command.

maybe this helps you, for single application, no tutorials, I use this script:

#!/bin/bash
CC=cc
CXX=g++
MOC=/usr/lib/qt2//bin/moc
MSG2QM=/usr/lib/qt2//bin/msg2qm

X_INCLUDES=-I/usr/X11R6/include
GL_INCLUDES=-I/usr/include
QT_INCLUDES=-I/usr/lib/qt2/include
OCC_INCLUDES=-I/opt/OpenCASCADE-50/ros/inc

X_LDFLAGS=-L/usr/X11R6/lib
GL_LDFLAGS=-L/usr/lib
QT_LDFLAGS=-L/usr/lib/qt2/lib
OCC_LDFLAGS=-L/opt/OpenCASCADE-50/ros/Linux/lib

LIB_X="-lX11 -lXext -lXmu"

CFLAGS="-DCSFDB -DNO_CXX_EXCEPTION -DNo_Exception -DLIN -DLININTEL"
CXXFLAGS="-DCSFDB -DNO_CXX_EXCEPTION -DNo_Exception -DLIN -DLININTEL"
LDFLAGS=-L/usr/X11R6/lib
LIBS="-lm -ldl -lc"

g++ $CXXLAGGS $X_INCLUDES $GL_INCLUDES $QT_INCLUDES $OCC_INCLUDES $LDFLAGS $X_LDFLAGS $QT_LDFLAGS $GL_DFLAGS $OCC_LDFLAGS $LIBS $LIB_X $LIB_QT $LIB_OCC $LIB_GL -o $1 $1.cc

Watch out, this is being used for gcc-2.95.3 and do not forget to set the executable-flag for the script: chmod +x yourScriptName

Good luck.
