I followed the INSTALL instructions of building Subsurface, and noticed the following interesting feature with qmake-qt5:
$ qmake-qt5 SPECIAL_MARBLE_PREFIX=1 Project ERROR: Unknown module(s) in QT: core gui network svg printsupport concurrent webkitwidgets webkit $ which qmake-qt5 /usr/bin/qmake-qt5 $ md5sum `which qmake-qt5` 0e73f80898a605447483620e1559fe40 /usr/bin/qmake-qt5 When running the qmake-qt5 with -d, the following interesting parts can be seen: DEBUG 1: visiting file /usr/lib64/qt5/mkspecs/features/qt_config.prf DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf: entering block DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:4: QMAKE_QT_CONFIG := /usr/bin/mkspecs/qconfig.pri DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:5: NOT DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:5: evaluating test function "exists" DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:5: calling built-in exists(/usr/bin/mkspecs/qconfig.pri) DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:5: test function returned false .... DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:6: calling built-in debug(1, "Cannot load qconfig.pri!") DEBUG 1: Project DEBUG: Cannot load qconfig.pri! DEBUG 1: /usr/lib64/qt5/mkspecs/features/qt_config.prf:6: test function returned true .... DEBUG 1: /home/poltsi/Work/Other/subsurface/subsurface.pro:7: calling built-in lessThan(QT_MAJOR_VERSION, 5) DEBUG 1: /home/poltsi/Work/Other/subsurface/subsurface.pro:7: test function returned true The latter part shows that the test for QT_MAJOR_VERSION fails. It is also curious where qmake tries to find the qconfig.pri since I have the following: $ locate mkspecs/qconfig.pri /usr/i686-w64-mingw32/sys-root/mingw/share/qt4/mkspecs/qconfig.pri /usr/lib64/qt4/mkspecs/qconfig.pri /usr/lib64/qt5/mkspecs/qconfig.pri /usr/x86_64-w64-mingw32/sys-root/mingw/share/qt5/mkspecs/qconfig.pri Looking at how the qt5-qtquickcontrols src-package is built (successfully), I noticed that it did not use qmake-qt5, rather /usr/lib64/qt5/bin/qmake. The funny part is this: $ ls -la /usr/lib64/qt5/bin/qmake -rwxr-xr-x 2 root root 3129984 Dec 10 22:02 /usr/lib64/qt5/bin/qmake $ md5sum /usr/lib64/qt5/bin/qmake 0e73f80898a605447483620e1559fe40 /usr/lib64/qt5/bin/qmake So it is the same binary. And of course: $ /usr/lib64/qt5/bin/qmake SPECIAL_MARBLE_PREFIX=1 $ So the qmake(-qt5) apparently looks at where it was called from. and uses that dirname to look for the rest of where qt5-stuff lies.
