CONFIG(release, debug|release) works, but where is "release" defined

[jronald]

In a test project

for debug: qmake.exe TestQt.pro -spec win32-msvc "CONFIG+=debug" "CONFIG+=qml_debug"
for release: qmake.exe TestQt.pro -spec win32-msvc

The qmake command below works as expected:

CONFIG(debug, debug|release) {
    message(debug build)
}

CONFIG(release, debug|release) {
    message(release build)
}

but where is release defined?

Hi @jronald, it's defined nowhere at the moment. You call qmake with CONFIG+=release for that.

@aha_1980 but the qmake command below works, why?

CONFIG(release, debug|release) {
    message(release build)
}

@jronald I guess release is the default...

[jronald]

@jsulm said in CONFIG(release, debug|release) works, but where is "release" defined:

me too, can't be sure

[jsulm]

@jronald If you're not sure then simply pass always release or debug :-)

[jronald]

@jsulm It works as expected, just want to know why.

@jronald
if you are using Qt Creator to build it comes from the current build setting in QtCreator.
You set that in the projects tab using the "edit build configuration" list box. or the mode setting flyout at the bottom left of the main window.
