Package: qt4-dev-tools
Version: 4.1.4-1.1
Severity: minor
I have a Qt4 app built from a qmake-qt4 / .pro generated Makefile.
Builds and works fine.
I wanted to add some OpenGL code to it, using QGLWidget.
I changed the CONFIG line of the .pro file from
CONFIG+= qt thread stl exceptions precompile_header release
to
CONFIG+= qt opengl thread stl exceptions precompile_header release
I was suprised that all this seems to do was to add -lGLU and -lGl
to the Makefile LIBS path: to get a QGLWidget I had to include
#include <QtOpenGL/QGLWidget>
(rather than simply QGLWidget as expected from the docs)
and to get a successful link I had to manually add
LIBS += -lQtOpenGL
to the .pro file.
I'd expect adding opengl to the .pro CONFIG to add the QtOpenGL
directory to the Makefile's -I include paths, and -lQtOpenGL to the
linked libs. (This is certainly the case with the qmake in
qt3 3.3.4 in Sarge).
If this is fixed in the qmake with 4.2.1, apologies.

Use "QT += opengl", not CONFIG. See the Qt4 qmake documentation for
more info.
