All,
There is a bug in default mkspec for the qmake generation of Makefile.
/usr/lib/qt3/mkspecs/linux-g++-64/qmake.conf contains:
QMAKE_MOC = $(QTDIR)/bin/moc
QMAKE_UIC = $(QTDIR)/bin/uic
Which works fine resulting in:
MOC = $(QTDIR)/bin/moc
UIC = $(QTDIR)/bin/uic
However, for the QMAKE variable in the generated Makefile, you have:
QMAKE = qmake
Which causes the build to fail because it calls qmake in /usr/bin (qt4-devel
qmake) instead of qt3 qmake in /usr/lib/qt3/bin.
Changing the generated Makefile to:
QMAKE = $(QTDIR)/bin/qmake
allows qt3 builds to work fine.
I'm not sure where the bug is, but it looks like the default mkspec needs to
also prepend $(QTDIR)/bin to qmake to ensure qt3 qmake is called. I don't know
if that can be fixed by simply modifying the default mkspec with:
QMAKE_QMAKE = $(QTDIR)/bin/qmake
I ran into this issue rebuilding a small personal project that provide a
spinbutton and slider to set the laptop brightness from 0-20.
You can reproduce the issue in 15.4 with the following minimum example:
#include
#include
#include
#include
#include "brightness.h"
int main( int argc, char **argv )
{
QApplication a( argc, argv );
form_brightness w;
a.setMainWidget( &w );
w.show();
return a.exec();
}
and the .ui file is:

Let me know whether this is a bug, or something that needs some other
workaround (sed ?).
