Your build seems to use make -jX where X > 1. If you build with make -j1 it stops where the error occured. In the spec file you can add: %global _smp_mflags -j1. Assuming you built it in copr, you can also search for "error: " in the builder-log.log.gz file.

The error message is a the end of the line in the first message :)

juce_CharPointer_UTF8_test.cpp:65:100: error: narrowing conversion

I don't now if #1314 is related to this one ...

Doh, missed that one as I did not scroll to the end of the line. Sorry for the noise. All I can offer is try to build with -Wno-narrowing and/or -Wno-error=narrowing but since it happens in a *_test.cpp file that is probably not a good idea :-)

Me neither. I just mentioned it because of aarch64.
