[Qbs] MSVC based profile: how SDK detection is working?

[Jochen Ulrich]

Hi Heiko!

The winSdkVersion inside MsvcProbe.qbs is an input which is set from the cpp.windowsSdkVersion property (see https://qbs.io//docs/qml-qbsmodules-cpp/#windowsSdkVersion-prop<https://qbs.io/docs/qml-qbsmodules-cpp/#windowsSdkVersion-prop>).

As it seems to me, the “detection” of the SDK version is done by MSVC itself. So, if you don’t set the cpp.windowsSdkVersion explicitly, then Qbs doesn’t know which SDK version it is working with. If you set it, then Qbs simply passes this to vcvarsall.bat to figure out the necessary environment variables (see vsenvironmentdetector.cpp, line 243-244<https://code.qt.io/cgit/qbs/qbs.git/tree/src/lib/corelib/tools/vsenvironmentdetector.cpp#n243>).

Best
Jochen

Hi together,

I'm currently fighting with getting Qbs working with MSVC 2022. Somehow the probing fails and I wonder whether this has sth to do with the SDK version: that is shown as being undefined when dumping it inside MsvcProbe.qbs.

So ... how do I tell Qbs which Windows SDK version to use? Or how is the detection working wrt. this?



Kind regards,

  Heiko
