Where does apt-get install libqt4?

Question

I've been searching for literally hours and I cannot figure out where for the life of me libqt4 is installed by apt-get.

I installed:

libqt4-dev
libqt4-core
libqt4-gui
libqt4-xml
libqt4-opengl

Next, I installed QtCreator 2.5.2 with the binary install file downloaded from qt-project.org because the QtCreator available in the Ubuntu repos is only 2.4.

QtCreator has to be able to find qt libraries and qmake on my system, but I can't even find them. Does anyone know where the $*(^#$(&^# apt-get installs them?

Solution 1

You can find out where files are installed with dpkg:

dpkg --listfiles libqt4-dev

Solution 2

So, after following roadmr's advice, I was able to find out that the libraries were installed in:

/usr/lib/x86_64-linux-gnu/

However, to set up QtCreator, one need only find the location of the qmake executable, which I believe Bodie was hinting at. It turned out that qmake (or qmake-qt4) was located in :

/usr/bin

Thanks to both for the guidace!

Solution 3

The library files are usually in /usr/include/qt4. The qmake is in /usr/bin/qmake-qt4 (or /usr/bin/qt4-qmake, I forget). You may have to symbolic link /usr/bin/qmake to either of these.

Perhaps your application expected the files to be in /usr/local/include... and /usr/local/bin... like some other distrubutions?

This is the sort of all purpose solution I was looking for. Googling for a way to show paths to packages installed with apt-get didn't show this...not even on the apt-get faq! Thanks so much.

The include files were indeed in /usr/include, but the libraries were actually installed in /usr/lib/x86_64-linux-gnu/.
