openssl/conf.h not found

[andrewkatson]

@zaucy and I are working on getting boost asio working with openssl. It already works with boringssl but we hit the following error when trying to build for MacOS. I am not sure if there are other issues with it but will re-run the checks to see.

Looks like ubuntu passes but Windows has an error on your side too https://github.com/bazelboost/asio/actions/runs/12381745142/job/34560955188?pr=5

but it seems intentional like this doesn't support Windows yet. I have my own openssl that works with Windows if you needed some help: https://github.com/andrewkatson/openssl

[andrewkatson]

We saw your recent release and now only Windows is outstanding!

@illicitonion can you PTAL

Thanks for the attention! Yeah I don't have the Windows expertise to get this going, but I'm happy to review a PR which did. I imagine it would take the shape of:

1. Add another platform to the platforms list in generate.py - I'm not sure which platform, as Windows has a few.
2. Edit BUILD.openssl.bazel to load constants from the newly generated .bzl file, and expand all the selects to cover the new constants.
3. Editing .github/workflows/pr.yaml to add windows-latest to the list of OSes in pr-test.

[andrewkatson]

I'll take a stab at it!

[andrewkatson]

Just an update. My computer isn't built yet so I haven't gotten the chance to work on it yet. I will though soon. If someone else wants to try that would also be good.

@illicitonion I finally got a working PC! But I dont understand where to find the list of platforms for openssl. I found some stuff like VCWIN-64A etc but am unsure what the specific strings are that I can choose from. I want to just support arm and x86 for now.

[andrewkatson]

I found them! https://github.com/openssl/openssl/blob/master/NOTES-WINDOWS.md

[andrewkatson]

@illicitonion Should the README be longer? I see in pr.yaml the steps to build and test but it is a bit unclear how I would do it all locally.

For now I just need help approving the workflows being run on #3
