Unable to build arrow on mac

I have updated XCode and since then I am not able to build arrow. I get the following error:

I don’t have llvm installed with brew.
This is the command I use: aliBuild build QualityControl --defaults o2-dataflow --debug

I am now trying with the defaults o2 but I doubt that it will help.

For the record, I have the same llvm from hombrew and it work for me. Did you update to the latest version of the homebrew package?

3

Do I need llvm from homebrew ? it is not part of the dependencies pulled by o2-full-deps.

I have updated all packages from homebrew after the xcode update.

EDIT: it is the same with the o2 defaults

ok, fixed I guess.

I readded llvm@13 and made sure to have it in the path (which I did not do before) and now it compiles arrow.

I don’t understand why we need llvm from brew if we have the one from the system.

I think at some point the one coming from the system was not working correctly. We should recheck if that is still the case.

6

yes or alternatively llvm should be added to o2-full-deps.

Dear people,
I ran into the same issue again today, and I seemed to have solved it by running
brew install llvm@14
and then I added it to my path with
echo 'export PATH="/usr/local/opt/llvm@14/bin:$PATH"' >> ~/.zshrc

EDIT: I actually had to remove the line from my zshrc because it then caused an issue when building ROOT.
Hope it helps,
Sarah
