Failing to build Julia 1.0.0 with llvm 6.0.1

Not sure if “Usage” is the right category for this. Mods, feel free to move if there’s a better spot.

I’ve been attempting to package Julia 1.0.0 for Void Linux, but I’m running into some issues that I’m assuming are caused by the fact that the system llvm I’m attempting to link against is 6.0.1 rather than the 6.0.0 used when llvm is vendored into Julia. I’ve applied what I believe all the patches are that didn’t make it into 6.0.1 (see this commit), but I’m still getting an error when building (see link to build logs at the end of this post). I’ve determined that this must be a problem with llvm by having all other dependencies vendored in and still get the same error.

The command I used to build was make prefix=/usr sysconfdir=/etc USE_SYSTEM_LLVM=1 USE_LLVM_SHLIB=1. Output from command is at this gist, where you can see the following error at the end:

I appreciate any help or insight anyone can give on this. Has anyone successfully built Julia 1.0.0 against LLVM 6.0.1? I don’t think packaging both LLVM 6.0.0 and 6.0.1 is really an option for most distros, and there’s obviously a strong preference to not have Julia vendoring in as large of a dependency as LLVM 6.0.0 especially when 6.0.1 is already packaged.

Julia applies a lot of patches to LLVM. AFAIK, using system llvm will not work in general.

Here is a list of patches applied to the dependencies:

Yep. I’ve applied those patches.

Hmm. I could try building with LLVM 6.0.1 real quick and seeing what happens.

It looks like master is already on LLVM 6.01:

Good find. Looking at the referenced PR, I’m guessing this is what I’m missing: Thanks!

EDIT: They actually reference the same issue I’m running into on the PR comment chain. This is definitely it. Thanks so much!
