qmake uses an incorrect Qt installation path on Linux… here is a solution to the problem.
qmake uses an incorrect Qt installation path on Linux
I compiled qt (qt-everywhere-opensource-src-4.7.4) using:
./configure --prefix=/edrive/local/qt
gmake && gmake install
When I want to create a new project with qmake
, create a makefile with the wrong path and point to the wrong binary and library directories:
> qmake -query "QT_INSTALL_PREFIX"
/edrive/local
In the makefile
Includes:
-I/edrive/local/include/QtCore
-I/edrive/local/include/QtGui
-I/edrive/local/include
Library:
-L/edrive/local/lib
User Interface:
/edrive/local/bin/uic
These are obviously wrong because qt is installed in /edrive/local/qt
.
Is there a way to fix this other than manually modifying the qt config file?
Am I doing something wrong?
By the way, it’s choosing the right qmake:
> which qmake
/edrive/local/bin/qt/qmake
Solution
You can change the value in the following ways:
# qmake -set VARIABLE VALUE
i.e. in your case:
# qmake -set QT_INSTALL_PREFIX /edrive/local/qt
Although from your qmake location, you called the wrong qmake.
Try
/edrive/local/qt/bin/qmake -query "QT_INSTALL_PREFIX"
I feel like you also have 2 Qt installed.
