Can't `make install` Qt compiled from source on Linux

timjrd

Hi, I need to compile the latest version of Qt, so I followed the tutorial on Qt's wiki and everything seemed to work fine except when I finally try to make install which gives me:

Cannot read /home/timjrd/repos/qt5/qtbase/mkspecs/linux-g++/qmake.conf: No such file or directory

I don't really know what to do. I'm on Ubuntu 16.04.

Any idea ?
Thank you :)

Hi, I redid the build from scratch and realized that one must not make install when passing the -developer-build flag to configure.

Now I can successfully use Qt from the build directory.

Thank you for your help and sorry for the noobery :)

Hi and welcome to devnet,

What exact parameters did you pass to configure ?
Did you do an out of source build ?

Except that a developer build is for people wanting to hack on Qt.

If you want to use Qt directly from the build folder, you should use -prefix $PWD/qtbase

@SGaist ok, I didn't notice that. Thank you !
