Phoronix: Building Mesa 11.0 With OpenGL 4.1 On Ubuntu Linux

I'm in the process of doing several interesting Mesa 11.0 tests with different GPUs as well as using the latest LLVM and Linux kernel code...

adding "ac_cv_path_LLVM_CONFIG=llvm-config-3.8" (without ") at the end of configure line(should work with autogen.sh too) should eliminate the need for "ln -s" command

I prefer renaming it to llvm-config since PTS will check for that binary to report LLVM details to the system information table, plus that I'm frequently doing Clang tests and other LLVM-based stuff on many systems to, so generally just set it and forget it.

Or just use openSUSE + pontostroy:X11 (SI Machine Schedule included)

"sudo make install" will more than likely cause some problems...
I have broken my system so many times with it...
Now I only make packages, easier to roll back.

>I prefer renaming it to llvm-config since...
But you are writing a guide for users, so I think a less intrusive way should be preferred

Meh. I jjust use a prefix of /usr/local and add /usr/local/lib to my library path before /usr/lib/*. Works fairly easily, and if I ever break my system, I can just rename /usr/local/lib to get things working again until I diagnose the failure.

... --enable-gless2 ...

You mean --enable-gles2 I guess.


Edit: BTW this should be enabled by default, as gles1 too.

Or just install it from the canonical-x staging PPA:

https://launchpad.net/~canonical-x/+archive/ubuntu/x-staging

only amd64 though, since llvm-3.7 isn't available on i386 yet

I have two questions:
1) What is the difference between pontostroy:gallium-nine, pontostroy:branches:homeontostroy:gallium-nine and pontostroy:X11

2) Sometimes I get an update and the 3d acceleration dies. The error I get is
libGL error: unable to load driver: r600_dri.solibGL
error: driver pointer missinglibGL
error: failed to load driver: r600libGL
error: unable to load driver: swrast_dri.solibGL
error: failed to load driver: swrast
What should I do?
For now I have installed the default mesa 10.3.7 for the 64 bit binaries and the pontostroy's mesa 11 in development for the 32 bit binaries.
I tried to use another repository for the latest stable version, but I get the same error.

Edit: the smile is unintentional. What a funny bug.

Don't you need to build the 32bit libs as well in order to have any effect on 32bit games (even if you are on a 64bit Linux distribution)?
