mapview.h:32:29: fatal error: QtWidgets/QWidget: No such file or directory

[foulowl]

Trying to build I get:

In file included from mapview.cpp:29:0:
mapview.h:32:29: fatal error: QtWidgets/QWidget: No such file or directory
 #include <QtWidgets/QWidget>

But looks like I have that file:

locate QtWidgets/QWidget
/usr/include/x86_64-linux-gnu/qt5/QtWidgets/QWidget
/usr/include/x86_64-linux-gnu/qt5/QtWidgets/QWidgetAction
/usr/include/x86_64-linux-gnu/qt5/QtWidgets/QWidgetData
/usr/include/x86_64-linux-gnu/qt5/QtWidgets/QWidgetItem
/usr/include/x86_64-linux-gnu/qt5/QtWidgets/QWidgetItemV2

This is both with the source tarball and git rev 851bbbc.

Thanks!

Did you succeed in building any Qt example project?
I don't compile for Linux, but it seems to be a Qt setup problem. So you should provide the path to your Qt installation in some way. This is mostly done via an environment variable:
set QTDIR=/usr/include/x86_64-linux-gnu/qt5/

I've got the same error. The problem was that I was using qmake for Qt4 which doesn't set up Qt5 include paths. With qmake for Qt5 (command qmake-qt5 in OpenSUSE) it works. Hope it helps anybody with similar issue.

Just to note that you can also do qmake -qt=qt5 to force qmake to use the qt5 version for those people with multiple Qt installs.
