I'm trying to build mesa with llvm linked statically with no luck

It seems this was easy a few years ago when the `llvm-libs` package still shipped static libs by looking at this: https://forum.artixlinux.org/index.php/ … 145.0.html

I modified the llvm-libs PKGBUILD to also add the `.a` libraries and now I have a bunch of them. But when I try to build mesa with `-D shared-llvm=disabled` I just get this error:

Okay please:

1. Post the PKGBUILD you were using
2. Post the exact command you were using that produced that output
3. Post the full output

Re: I'm trying to build mesa with llvm linked statically with no luck

Okay please:

1. Post the PKGBUILD you were using

2. Post the exact command you were using that produced that output

3. Post the full output

1. It is the existing llvm-libs PKGBUILD modified to include the static libs: https://pastebin.com/WygAf2jz

When installing I noticed that this modified llvm-libs contains a few static libs that conflict with the existing llvm package, those were overwritten in that case, I don't think this is a problem given that both files get produced by the same PKGBUILD and llvm is split into two separate packages but let me know.

2. I took the existing mesa PKGBUILD and added the [-D shared-llvm=disabled] to meson_options: https://gitlab.archlinux.org/archlinux/ … heads#L182

3. https://pastebin.com/xjrqmq8b

https://pastebin.com/af9qS96h

Edit: I just noticed that I got a different error this time after repeating the steps lol

Re: I'm trying to build mesa with llvm linked statically with no luck

mesa needs a lot more then just llvm-libs .

You will very likely need to provide static builds of llvm , clang and libclc . Also a build of spirv-llvm-translator against your static llvm .

Look again at the llvm repo PKGBUILD .

# Utilizing LLVM_DISTRIBUTION_COMPONENTS to avoid
# installing static libraries; inspired by Gentoo
_get_distribution_components() {

The _get_distribution_components() function was specifically added to get rid of static libraries, you'll have to remove any usage of that function.
