QApplication: No such file or directory

[Lykurg]

Humm ... i found qmake in /usr/bin( lrwxrwxrwx 1 root root 23 Abr 27 16:10 /usr/bin/qmake -> /etc/alternatives/qmake ) and /usr/local/Trolltech/Qt-4.5.0/bin

That's good so, because Qt uses ($QTDIR)/bin/qmake and ($QTDIR)/include, so simple change your system variable and all should work fine!

I had no idea that qmake was already in a fresh install.
This is were my confusion started.
I will try again after building Qt.

uff...it's OK again.
After a fresh install and building Qt again i went back to the environment variables issue.
I edited /etc/profile and added this lines:

QTDIR="/usr/local/Trolltech/Qt-4.5.1"
export QTDIR
 
PATH=$QTDIR/bin:$PATH
export PATH

QTDIR="/usr/local/Trolltech/Qt-4.5.1"
export QTDIR

PATH=$QTDIR/bin:$PATH
export PATH

One thing is still bothering me ...

./usr/share/qt3/bin/qmake 					( lrwxrwxrwx 1 root root 22 Jun 14 19:16 qmake -> ../../../bin/qmake-qt3 )

Got lost here trying to follow the simbolic links ... but looks like "there are no alternatives to qmake -> /usr/bin/qmake-qt3" ... at least i don't know how.

For building Qt you don't need any settings. Just invoke the qmake of your "source-directory" only after successfully build it you must tell the application you are going to build which qmake to use. You can do it over your ~./profile, create new symbol links or simply call the qmake with the full path. That on your system are also qmake-qt3 is no problem at all. Just make sure, that a simple "qmake" in your console reaches the right qmake. (I'd preferre the ~/.profile approach.)
