root6 @6.24.00_2+cocoa+davix+gcc10+graphviz+gsl+opengl+python37+roofit+tmva+xml+xrootd: Build failed

[Tommaso93]

Dear expert(s), during a port upgrade, the root6 port fails with the attached log. Every other dependency has been previously upgraded.

Best, Tommaso

Pretty sure this is not a root issue, but another issue caused by

#62770

i.e. the macOS11.3/Xcode12.5 update broken macports clang.

Ken has fixed clang-11 and clang-10 but not (yet?) clang-9.

[cjones051073 (Chris Jones)]

b.t.w. unless you specifically want python 3.7 support, 3.8 is now the default so if you switch to using just the default variants you will get the binary tarball install as that built fine

I used python 3.7 for convenience, since I have all the packages there. But I can switch, if that port works fine! Thank you for the info. When clang-9 will be fixed, maybe I'll move back to the other version.

[cjones051073 (Chris Jones)]

Thats fine, but just note we are actually in the process of migrating to python 3.9 as the default (I will likely change root at some point) so by sticking with 3.7 as your preferred variant you will be forcing a number of ports to be built from source, whereas if you used the default you would benefit from the binary installs.

clang-9.0 has now been fixed for BigSur / Xcode 12.5 so I hope this fixes this issue for you.

Replying to kencu:

clang-9.0 has now been fixed for BigSur / Xcode 12.5 so I hope this fixes this issue for you.

Is this still an issue?
