Uploading Python packages to PyPI for Linux distributions requires the code to be compilable on an old CentOS system (the "manylinux" distribution uses CentOS 6). Not sure if it is going to be a problem. In particular, I am not sure how challenging it is to compile the latest llvm version there. C++14 support might also be tricky (but not impossible).

[alexreinking]

That's good to know. I wonder if there are Docker images with CentOS 6 and recent development tools. Otherwise, we could probably set up a buildbot with a custom built GCC for this. Painful, but done once, and probably worthwhile.

Yes there are docker images: https://github.com/pypa/manylinux

An old release is on vcpkg. See #4539 . We should work with them once #4644 lands to see what they would like out of our build.

Hey @alexreinking, happy to help get this on Homebrew. I started a formula here. Two things that would help are:

1. A make install task
2. A new release. The latest release fails with error: no viable conversion from 'int' to 'llvm::MaybeAlign', but the current master branch builds successfully

[alexreinking]

PR #5135 begins versioning Halide with semver at 10.0.0

[alexreinking]

@ankane - a new release is imminent. Does Homebrew require make install specifically, or would cmake --install /builddir --prefix /installdir suffice?

[ankane]

Awesome, cmake --install works just as well.

[alexreinking]

@ankane - we just released Halide 10.0.0. Please let us know how to help you get it on Homebrew :)

I just reached out to the folks at vcpkg, too. See microsoft/vcpkg#13580

[ankane]

Thanks @alexreinking! I've submitted it to Homebrew here: Homebrew/homebrew-core#61246

[alexreinking]

Awesome, @ankane! Keep us posted

Time to look into Python packaging. I'll look into pip and conda. This means trying to build Halide in a manylinux docker image, and set up scripts for bots.
