Build issue with ITK on Apple Silicon #1619

Open dcoeurjo opened 2 years ago

dcoeurjo commented 2 years ago

When build DGtal on a M1, there is no problem except when setting -DWITH_ITK=true which produces:

Consolidate compiler generated dependencies of target DGtal

Have you already experienced something like that @kerautret ?

kerautret commented 2 years ago

yes I see it on the GitHub Actions when trying to activate ITK on MacOS build, it looks like that the include of cmath.h from Xcode build system find first the math.h of /usr/local/include before the one of Xcode Tools chain.

Same problem here trying to activate ITK and macos GitHub Actions: (with a cmake small try fix) https://github.com/kerautret/DGtal/runs/4445372646?check_suite_focus=true

@dcoeurjo have you tried to use the the CommandLineTools SDK instead the XCode SDK, by using: sudo xcode-select -s /Library/Developer/CommandLineTools It looks to be better when using ITK from brew (I tested on my non M1 Mac it works while also failing with Xcode SDK)

THanks for the tip, I'm not super fan of changing the SDK globally.. (I wasn't expecting that the command line has a different sdk than Xcode.. weird..)

I am agree not ideal, for instance I detected that Unreal Engine was no more working by using this SDK! 😱

@dcoeurjo I tested a simple ITK helloworld project and it fails from the same errors so the problem is not related to DGtal itself but more from brew/ITK/osXSDK. I try to ask it on the ITK dev forum if they get a good workaround to fix it :). (since just test using #include and no errors).
