Mageia forum

Greetings,
I have a question/request regarding the mesa package. I would be interested in running the Cyberpunk 2077 on my Linux install which is officially supported with the new Proton 5.13-4 but currently to do that it requires having mesa 21.0 which I assume is available only from the git directly (since Mga7 has mesa-20.2.3-1 and Cauldron has mesa-20.3.0-2).

I've only managed to make a few backports for my Mageia 7 installation for example corectrl from Cauldron so I don't have much experience with packaging and I have no idea how to package it if I would (managed to) build the mesa myself. So if you are or you know someone who would be able (and willing) to build or help me build mesa 21.0 package for Mageia 7.1 it would be very appreciated. I have no idea if it might be even possible (because of some dependencies or idk).

Thanks in advance for your replies
Cheers

mesa has recently been updated, and since we're approaching Mageia 8 final release, I don't think there will be another update to a new mesa release, even less as mesa 21 is not even close to being released as a stable release AFAICT.
My suggestion would be to grab the latest cauldron src.rpm and try to update it yourself. FWIW it already includes a small shell script to grab a snapshot from latest git snapshot.

FWIW, I've tried a local build on 7.1 based on the cauldron src.rpm and it builds just fine, not that many changes were needed.
You'd need to install the cauldron src.rpm, apply those differences and download a mesa git snapshot with the mentioned script.

Greetings,
so I downloaded the src.rpm, unpacked it (I had the build structure from doing my previous backports), made the changes to the .spec file to match your example above, used the script to download latest git, downloaded all dependencies via "sudo dnf builddep mesa.spec" and used the "rpmbuild -ba mesa.spec" to build it.

Now I'm stuck with this build error:

Code: Select all

What does your ~/.rpmmacros look like ?

It should be the default example provided on the wiki.

Well, here the debugsources packages are partially empty. Have a look at https://wiki.mageia.org/en/Packaging_pr ... ebug_Files

So... the build finished successfully and I've installed all of the generated rpms. However, the installation would not proceed until I removed the 32bit "libmesagl1-20.2.3-1.mga7.i586", which at first I had no idea how I got in the first place. After removing this package the new mesa and everything with it installed successfully. After that, I restarted my computer just for a good measure.

Great so now I checked the mesa version with "glxinfo | grep OpenGL" which was reported as Mesa 21.0.0-devel woohoo. Nice so now to open Steam and check how'll the Cyberpunk run... and oh my god... there is no Steam...

It seems like the 32bit package I removed earlier is (for some reason) a hard dependency of the steam package and since it's version 20.2.3-1 I won't be able to install it alongside 21.0. Well that's not frustrating at all xD

Code: Select all

The following packages can't be installed because they depend on packages
that are older than the installed ones:
libdri-drivers-20.2.3-1.mga7
libmesagl1-20.2.3-1.mga7
steam-1.0.0.61-1.mga7.nonfree
Continue installation anyway?

Well, you might need to also rebuild for i586, but for that you would need iurt (cf https://wiki.mageia.org/en/Packagers_Me ... Howto#iurt ) or some other chroot.
But you'd only need that for i586 software (e.g. steam).

Oh, I hoped that I could just do "rpmbuild --target=i586 -ba mesa.spec" but it's not easy like that apparently xD

meson.build:21:0: ERROR: Compiler cc can not compile programs.

No, you cannot cross-compile like that.

I'm wondering if it wouldn't be better to rebuild the Steam client from the backport to use mesa 21.0 from the start.

EDIT: Tried that and the Steam won't run using the 64bit libraries because it's forced to use 32bit ones. There is also an error message made directly for this. Worth a try tho. I guess back to making 32bit Mesa libs :D

EDIT 2: I really have no clue how to do it using the iurt you suggested so I guess I'm just gonna build it in the Virtualbox 32bit Mageia :p

You basically just install iurt, and use one of the commands to rebuild from your src.rpm into a i586 package.
Check https://wiki.mageia.org/en/Packagers_Me ... Howto#iurt

One of the examples is this:

Cross compiling from x86_64 to i586:

  --rebuild cauldron i586 ./SRPMS/abiword-2.8.6-1.mga1.src.rpm

Greetings,
I've already had the 32bit Mageia 7.1 installed on my VMware from some weeks ago (I was showcasing the distro in my Unix class assignment) so I've just used that to build 32bit Mesa 21.0. After that, I installed the "libdri-drivers-21.0-1.git20201213.1.i586.rpm" and "libmesagl1-21.0-1.git20201213.1.i586.rpm" to satisfy and install (back) Steam.

Everything is working as it should and the performance is indistinguishable from Windows running the game on my setup (also it was astonishing to have working Proton with CP2077 on day 1). Thanks again for the help, Dok! Marking as solved. o7
