Using g++ compiler for building macOS packages.

[agudys]

Hello,

In our software we use some modern C++ multithreading features. Unfortunately, these features are currently not supported by clang and require g++-11 or higher for compilation. Therefore, I would like to ask if there is some way to deploy macOS package with g++ compiler instead of clang.

Thank you!
Adam

Do you talk about #47764 ?

Hello,

We started the discussion under the thread you have mentioned, but it actually concerns #49740. Sorry for the confusion!

Best,
Adam

I was looking at this too for bindash (added in #18853 without macOS support). The authors say on https://github.com/zhaoxiaofei/bindash they recommend gcc 13 for compiling on macOS. I asked on Gitter last week:

Björn also suggested looking at conda_build_config.yaml but I couldn't find a precedent.
