Custom mesa-git on ubuntu 18.04
f95-2 Oct 31, 2018
Hello.
I am trying to use custom-compiled mesa on my ubuntu.
I know that there are ppa's with already compiled mesa, but for some reason i do not want to use them, and want to compile it myself.


So I dowloaded llvm7, got mesa sources, did
CC=/opt/llvm-7/bin/clang CXX=/opt/llvm-7/bin/clang++ LLVM=/opt/llvm-7 scons build=release
and compilation seems to be alright.

I got build/linux-x86_64 folder with some stuff.

However, I cannot figure out what to do next.
Guides I found in internet seems to be outdated or I just cannot understand them.

Could you guys show me direction?

Have you looked on our Wiki Page? I didn't write it and I don't use Mesa personally, so not sure how much help it will be. Just in case you didn't see it.

It is not working for me at step 2 :)

sudo apt-get build-dep mesa

Got the error

Вы должны заполнить sources.list, поместив туда URI источников пакетов

(in Russian, yes. It means I have to fill sources.list by placing URI of package sources there).
Cannot find how to fix that.

Also, in the guide, the author wrote
QuoteI checked how the official distro package is configured

However, ob Ubuntu there is no 'mesa' package, but bunch of packages like mesa-utils, mesa-common-dev and so on.
Have no idea which configuration I have to use.

Haven't tried it my self yet, but the official build instructions seem fairly straight forward;
https://gitlab.freedesktop.org/mesa/mesa#build-install

Current meson version for 18.04 is 0.45.1 so that should work?

Managed to reproduce the "fill in sources " error on a blank machine, the fix is;

- open "Software & sources" from the menu
- check the "Source code" box
- Close ( & reload )

now sudo apt build-dep mesa will work


However meson still can't build on my 18.04 - because libdrm_intel is too old ( need 'libdrm_intel' ['>=2.4.95'] found '2.4.91' )
