Godot crashes at startup if the supported OpenGL version is too low

[swenner]

Master (1.1beta), 32bit debug build, Ubuntu 14.04. Executable: godot.x11.tools.32
Segfaults at start up.

Godot should print a friendly message, that it can't run. What are the minimal requirements to run the engine?

Program received signal SIGSEGV, Segmentation fault.

Confirmed on LUbuntu 14.10 32 bits
Graphic board : Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)
All drivers up-to-date (or maybe I should upgrade to the most recent Ubuntu version ?)

Actually, it is quite a pain that Godot can't work on old devices.
As you say, it shoud at least print a nice message before crashing.

I tried to print a nice message, but it crashes and I don't have an old
device to test why. patch for this welcome :)

I'm affected by this too, on one of my 3 machines. An old 2008 era laptop running Windows 7 Ultimate. GPU Caps Viewer says "Mobile Intel(R) 4 Series Express Chipset Family", GMA 4500MDH. GL_VERSION 2.1.0, GLSL version 1.2.0. It's a DX10 class part, but looking at some forums, Intel didn't bother to do OpenGL 3.x for these devices. OpenGL is definitely a deployment problem for old Windows laptops with integrated graphics.
