OpenGL (mesa) support

[ghost]

Hey,

I want to develop an application with glfw3 and glew and seem to be hitting a limitation on my drivers. Functions I want to use, need at least OpenGL 2.1, but

glxinfo | egrep 'OpenGL|vendor|version'

only outputs

glxinfo | egrep 'OpenGL|vendor|version'
server glx vendor string: SGI
server glx version string: 1.4
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
GLX version: 1.4
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile 

Could it be, that I have installed the wrong mesa packages? I followed this guide from stackoverflow: http://stackoverflow.com/questions/17768008/how-to-build-install-glfw-3-and-use-it-in-a-linux-project/17772217 (the top answer).

dpkg -la | grep -i mesa

Shows this:

My Chromebook is the HP 14 with 4gb and this is my croutonversion output:

It looks like you reverted back to the non-lts-trusty packages. Try updating your chroot?

[ghost]

Man, I should really just do that before every issue... Any idea why I wasn't using the trusty packages?

[dnschneid]

You probably ran the sudo apt-get install ... libglu1-mesa-dev line which reverted you to the non-trusty versions.

[ghost]

How should I install these packages then? I ran the program once, it worked, changed something, now it doesn't find a bunch of these libraries lxrender, lxrandr etc.

[dnschneid]

Try looking for -lts-trusty versions of the packages.

I promise I won't ask anything more... :D http://packages.ubuntu.com/precise-updates/libgl1-mesa-dev-lts-trusty This would be correct?

[dnschneid]

That looks about right. Actually, reporting back with your findings is very useful, since it's possible that someone else will hit a similar issue down the road.

Alright to add more findings: I had to install these libraries all one by one also:

libxcursor-dev libxrandr-dev libxinerama-dev
