qt/5.15.1: build iOS + xcode 12

[cajus]

Did anyone manage to compile Qt for iOS/xcode 12 yet? While building the dependencies for iOS and macOS seems to work fine, qt only compiles for macOS. iOS runs directly into:

===================
Maybe you forgot to setup the environment?

This looks like some misconfiguration or simulator/device mixup. But I'm really not enough Apple guy to see what's going on there. Any ideas?

this looks like https://bugreports.qt.io/browse/QTBUG-86718

[cajus]

Ah. I did some search foo on the bugtracker there, but I didn't find that one. Thanks! Although the issue is about building a project instead of Qt itself, they may be related.

[pawelgontarz]

Hi, i have the same problem as You. Everything worked on xcode 11.7. Did you find a solution?

[cajus]

Yes. You can add this patch to your qt conan recipe for now: https://codereview.qt-project.org/c/qt/qtbase/+/314636

[ericLemanissier]

This recipe is now in the Conan Center Index.

Please migrate to the recipe version there. If this is still an issue, please create a new issue in the Conan Center Index issue tracker.

Thanks!
