Unsolved qmake and Qt installation root directory
Swen Laur last edited by
How could I refer to Qt installation root directory available in shell as qmake -v. Is there a special qmake variable or a way to store the outcome of qmake -v in a variable.

Assuming you want to store the outcome in a qmake variable (as opposed to, for example, a shell script variable), then there's a few built-in variables that probably have what you're after.
The special $$[...] operator can be used to access qmake properties
So, for example:
paul@paul-XPS-13-9343:~/tmp$ cat messages.pro message(Qt version: $$[QT_VERSION]) message(Qt is installed in $$[QT_INSTALL_PREFIX]) message(Qt resources can be found in the following locations:) message(Documentation: $$[QT_INSTALL_DOCS]) message(Header files: $$[QT_INSTALL_HEADERS]) message(Libraries: $$[QT_INSTALL_LIBS]) message(Binary files (executables): $$[QT_INSTALL_BINS]) message(Plugins: $$[QT_INSTALL_PLUGINS]) message(Data files: $$[QT_INSTALL_DATA]) message(Translation files: $$[QT_INSTALL_TRANSLATIONS]) message(Settings: $$[QT_INSTALL_CONFIGURATION]) message(Examples: $$[QT_INSTALL_EXAMPLES]) paul@paul-XPS-13-9343:~/tmp$ qmake Project MESSAGE: Qt version: 5.4.2 Project MESSAGE: Qt is installed in /usr Project MESSAGE: Qt resources can be found in the following locations: Project MESSAGE: Documentation: /usr/share/qt5/doc Project MESSAGE: Header files: /usr/include/x86_64-linux-gnu/qt5 Project MESSAGE: Libraries: /usr/lib/x86_64-linux-gnu Project MESSAGE: Binary files (executables): /usr/lib/x86_64-linux-gnu/qt5/bin Project MESSAGE: Plugins: /usr/lib/x86_64-linux-gnu/qt5/plugins Project MESSAGE: Data files: /usr/share/qt5 Project MESSAGE: Translation files: /usr/share/qt5/translations Project MESSAGE: Settings: /etc/xdg Project MESSAGE: Examples: /usr/lib/x86_64-linux-gnu/qt5/examples paul@paul-XPS-13-9343:~/tmp$ qmake -v QMake version 3.0 Using Qt version 5.4.2 in /usr/lib/x86_64-linux-gnu
So, at least on my installation, it looks like
$$[QT_INSTALL_LIBS]is equivalent to the path given in
Just out of curiosity, what you want that value for?

Please note, in my post above, all the instances of
[should be preceded by two
$chars, not one... for some reason this forum (or my browser) keeps switching between showing one and two.
For example, they should look like
$ $ [QT_...](ignoring the spaces).
If in doubt, just look at the examples in http://doc.qt.io/qt-5/qmake-language.html#accessing-qmake-properties - they're formatted correctly.
