I wasn't able to tweak this to be able to build a cross compiled mesa. I
was able to build and run glxgears on core-updates with this patch
applied.

Nice!
Not sure if you already saw my message on guix-devel
https://lists.gnu.org/r/guix-devel/2023-01/msg00218.html but I'll just
repeat the summary: looks like latest mesa wants latest llvm (llvm-15 to
be exact) for current hardware support. I think this is the summary:
https://www.phoronix.com/news/LLVM-15-Branched
Have you tried with other versions of llvm?
I haven't checked what version of mesa is in core-updates or any pending
patches, but I can send an update to the latest version if needed.
I also haven't reviewed/tested this patch, but I do use current mesa via
another channel where I could try it out with this modification for
testing and get back to you.
Thanks for working on this!
John

I was going to start with llvm-15 but currently core-updates only has up
to llvm-14 and mesa is currently built there with llvm-13, so that's
what I used. I also ran into a number of cross compiling issues while
trying to test cross compiling on core-updates so I think I'll try
working it on master so it can be more easily tested, and then when it's
good I'll commit it to core-updates. I'll also see about a
master->core-updates merge.
For the next version of the patch I think I'll copy the static libraries
to a static output instead of deleting them. I'm not sure exactly where
they'd be used, but at least in a different output they won't add to the
closure size if we need them and they're available if needed.

I've rebased the patch on top of master which should make testing it
easier. I tested it with glxgears from mesa-utils.
The first patch is just the patch backported.
The second patch makes some small adjustments so that the version of
mesa in master can be built with llvm-for-mesa.
When the patch is ready for inclusion we have a choice between merging
master into core-updates and then applying it, so we can keep llvm-15 as
base-llvm, or I can commit it to master with a TODO that it should
replace the llvm input in mesa in core-updates.
Efraim Flashner (2):
gnu: Add llvm-for-mesa.

Should we pass -DDISABLE_STATIC=ON or whatever it’s called instead?

Why do we need this extra phase compared to ‘llvm’? Please add a

The non-literal pattern here, and that it explicitly refers to the build
directory, is not great.
I believe you can use (string-append (getcwd) "/lib") as the pattern,
fixing the second problem. Not sure about the first one.
Thank you!

I don't have a strong preference. By leaving it as 'llvm' we make it
more easily substitutable by any other build of llvm since they'd have
the same name length. Having it as 'llvm-for-mesa' makes it really clear
what it is.

That's right. I tried with just (system->llvm-target) but AMDGPU was
needed for the vulkan drivers.

It turns out that static is the default, and we override it in most of
the llvm packages to build shared libraries instead. If we disable the
static ones too then it errors out and says it has nothing to build.

Fair enough :) It turns out that *everyone* expects llvm-config to
exist, and doing it this way allows us to only build llvm-config, not
all the tools/utilities.

I suppose it would be (string-append (getcwd) "/bin/lib") to fix both. I
wasn't able to find a good way to get llvm-config to be configured
correctly by the build system without also having it install all the
utilities. When I looked in the build directory after a RUNPATH failure
it had that directory as the one to link to for the libraries.

This one's been bothering everyone for years :)

This patch is to allow testing llvm-for-mesa while allowing the actual
patch to be cleanly shown.
* gnu/packages/gl.scm (mesa)[inputs]: Replace llvm-11 with llvm-for-mesa.
* gnu/packages/llvm.scm (llvm-for-mesa): Inherit from llvm-14.
[arguments]: Inherit package arguments from llvm-15.
