<pre>I started to play around with modules and ran into the following error:
fatal error: file
'/home/milian/projects/compiled/kf5/include/KF5/KDBusAddons/module.modulemap'
has been modified since the module file
'/tmp/org.llvm.clang.milian/ModuleCache/1R4DPWZPQLPIB/QtCore-2B4VMXDD7IFGQ.pcm'
was built
note: please rebuild precompiled header
'/tmp/org.llvm.clang.milian/ModuleCache/1R4DPWZPQLPIB/QtCore-2B4VMXDD7IFGQ.pcm'
Note that the KDBusAddons module depends on the QtCore module here. Right now
I'm failing to find an easy way to reproduce this issue - I work-arounded it by
pruning /tmp/org.llvm.clang.milian in the meantime.
In general, couldn't the above scenario be handled more gracefully by
implicitly rebuilding the precompiled header? I.e. why is manual
user-intervention required here?</pre>
