Description

When trying to remove some unrequired features/modules , the build fails with precompiled headers enabled. How, when using the configuration flag -no-pch the build compiles just fine.

Below are the two configure calls that were used:

../qt6/configure -no-feature-undogroup -no-feature-undocommand -no-feature-undoview -no-feature-undogroup -no-feature-designer -no-feature-linguist -skip qtquick3d

Whereas

../qt6/configure -no-feature-undogroup -no-feature-undocommand -no-feature-undoview -no-feature-undogroup -no-feature-designer -no-feature-linguist -skip qtquick3d -no-pch

compiles as expected.

Am I missing something here?

I followed the guide to build from git found here: https://wiki.qt.io/Building_Qt_6_from_Git
