llvmlite[On hold due to Conda support]

[khmyznikov]

@lowkeyrossi let's keep the discussion here

[khmyznikov]

LLVM for WoA binary does not comes with llvm-config.exe and llvm-config.cmake which are required to build llvm-lite wheels. Need to open the issue for https://github.com/llvm/llvm-project and try to build it locally in debug mode.

[Greenie0701]

@khmyznikov I am not sure how LLVM folks would help us here, since they would not be able to re-release older version of clang+llvm package(let say in our case 15.x) for WoA.

But, locally building llvm+clang (v15.x) and try to build llvm-lite would be possible way to get a working llvm-lite wheel for WoA. But, making this local build llvm+clang package available for public would be difficult task.

[khmyznikov]

@lowkeyrossi I think the question is, would llvmlite maintainers accept the PR where you built llvm first and then the wheel. Don't mind create the issue and ask them? Maybe they'll have some thought on this problem too.

[Greenie0701]

@khmyznikov Got it, I guess they would consider this, but the only concern would be the amount of time taken to complete the CI job for building both llvm and then llvm-lite wheel.

But yeah we can have a PR raised and lets check with llvm-lite folks!

[Greenie0701]

@khmyznikov got a working llvm-lite wheel for Windows ARM64, probably the next step would be raising a PR with necessary changes!

[Greenie0701]

The build is actually going beyond 1hr 40mins, you can check it out from here

[khmyznikov]

@lowkeyrossi yeah that's too much... Probably we had to contribute llvm-project first

[Greenie0701]

@lowkeyrossi yeah that's too much... Probably we had to contribute llvm-project first

So for basic testing I have created sample repo, and uploaded the llvm-arm64 local build binary and building llvm-lite with that

[Greenie0701]

I guess we can request llvm guys to provide llvm+clang 15.x Binaries as we are blocked due to this

[khmyznikov]

@lowkeyrossi but will it have llvm-config.exe and llvm-config.cmake?

[Greenie0701]

@lowkeyrossi but will it have llvm-config.exe and llvm-config.cmake?

Yes, it contains the necessary files, since I have compiled LLVM locally, and uploaded it on the sample github repo release.

Installer of LLVM will not contain these files, since LLVM guys are removing due to some reasons.

[Greenie0701]

I could see there is already existing build scripts in llvm-lite repo for building llvm for X64, I guess we can reach out to llvm-lite guys for moving this forward.
