Not sure if there are performance reasons to favor STL vectors on gcc, but otherwise would it make sense to use boost on gcc too? Mostly to avoid the ifdefs. |

I don’t think universal2 wheels are particularly useful. It would be nice if we could cross-compile x86_64 wheels on arm but the docs only talk about cross-compiling for arm on intel: https://cibuildwheel.readthedocs.io/en/stable/faq/#how-to-cross-compile |
|
What’s the best way to test out building with clang. these changes seem more intrusive than need be |
We’ll likely cross-compile to arm from x86 as the x86 mac runners are more plentiful on github actions than the arm runners (at least as of right now) |

I looked at building with clang on RHEL 7 today. It looks like all you need to do on top of the conda-forge environment created from Then build I tried first with the There are some compiler warnings and for whatever reason |

I just tried this and it bombed early on when building its deps ( bombed in boost build )

I can try building deps first with gcc then csp with clang

Hmm, I think that might be provided by |

Looks like its mixing up clang and gcc for some reason, is that expected?

Somehow when I did this earlier I ended up with clang 14, which doesn't seem to hit the issue you're hitting. You could try downgrading clangdev with When I created a new environment from scratch I ended up with clang 17 and hit the same error you did compiling Another thing we could try is a chimera linux or FreeBSD docker image or VM image - both systems are built on LLVM so we won't hit any issues from mixing LLVM and GCC. |

Thanks Nathan, I was able to get this to work and have cleaned up all the clang build issues.
I have the changes ready but still cant push to GH from on-prem, I’m hoping they’ll have a fix ready tomorrow
