SOLVEDHelp with mesa gallium nine install (Debian 9 Stretch)

[lando32]

Hello all,

I've been trying to install mesa with gallium nine, and I'm trying to compile it from source. I try to run the autogen.sh script that comes with it and I get the following error:

Code: Select all

configure: error: LLVM 3.9.0 or newer is required for r600

when trying to run

Code: Select all

sudo sh autogen.sh --enable-nine --enable-llvm

autogen.sh requires LLVM 3.9 with llvm-config, so I thought that would come with llvm-3.9-dev, but whenever I delete llvm-3.8-dev and install llvm-3.9-dev, it says that I don't have llvm-config installed at all.

Any help with this is appreciated. Thanks.

Edit:

I solved the issue now, I had to go add the LLVM nightly PPA, add the archive signature key, and then update & upgrade

I would not say that a PPA is really solving the issue at all.

Why not backport the upstream Mesa packages or rebuild the one in stretch-backports with gallium 9? Backports also has llvm-5.0 and llvm-6.0 that are necessary...I'm running Mesa 18.1.3 on a Stretch base right now, in fact.

You have not solved this problem, but only more complicated. Congratulations. You created a FrankenDebian

Sorry, I meant that I added the llvm repo to my sources.list file, and then updated. I just got off ubuntu, so I'm still calling them PPAs. I'll get better eventually

Good thing that I didn't add a PPA then. I didn't know that they are an issue on Debian. I'm guessing using backports is the better option then?

I believe that the LLVM third party repo team does a good job of making sure that their packages are compatible with the target Debian release. in contrast, PPA packagers don't build Debian packages at all; Launchpad only builds on Ubuntu platforms. They may or may not work on Debian, but have often created issues in the past.

The backports repo is maintained by Debian, see backports.org.

Yes, of course.
