Source: qt6-base
Version: 6.3.1+dfsg-10
Severity: important
Tags: patch ftbfs
Justification: fails to build from source (but built successfully in the past)
The build fails with:
/<<PKGBUILDDIR>>/src/corelib/plugin/qelfparser_p.cpp:178:4: error: #error
"Unknown Q_PROCESSOR_xxx macro, please update."
Full log at:
https://buildd.debian.org/status/fetch.php?pkg=qt6-base&arch=alpha&ver=6.3.1%2Bdfsg-10&stamp=1664652510&raw=0
Attached is patch to provide the Q_PROCESSOR defines for Alpha. With
that qt6-base builds successfully.
Cheers
Michael.
