Easy cross platform way to detect architecture in Qt Pro or QMake system?

tmason101

Hello,

I am wondering how I can create a Qt Creator / Qmake .pro file which can detect whether I am building for a 32-bit or 64-bit environment

See the following code below for my current, working .pro file. The section that I commented out is for 64-bit builds.

*What I would love is that there is a way for the build system to detect the 64-bit section based on architecture and activate that section in the same way that I can activate the sections for debug versus release.

Bonus if this can be cross-platform.

Thank you for your time!*

Hi,

IIRC you can use

@contains(QMAKE_TARGET.arch, x86_64) {
// cool 64bit stuff
}@

for that

Hope it helps

This works!

What's great is that you can switch easily between 32-bit and 64-bit like so:

@
contains(QMAKE_TARGET.arch, x86_64) {
// cool 64bit stuff
}

!contains(QMAKE_TARGET.arch, x86_64) {
// cool 32bit stuff
}
@

@
contains(QMAKE_TARGET.arch, x86_64) {
// cool 64bit stuff
} else {
// cool 32bit stuff
}@

Would be cleaner
