Check OpenGL version and print a clear error message about endless-sky HOT 9 CLOSED

Work around by switching to proprietary drivers instead of using Nouveau drivers.

from endless-sky.

Yes, the game requires at least OpenGL 3.0, which is GLSL version 1.30. That message is saying your Nouveau drivers only support GLSL 1.20, which is OpenGL 2.1.

I will modify the program to check your OpenGL version on start-up and to print a clearer and more informative error message. And, I'll make sure the next release includes a note that OpenGL 3.0 is needed. Sorry about that!

Thanks for letting me know. I've renamed the issue to better describe course of action.

Fixed in 822adca. Can you try switching back to the Nouveau drivers and verify that you receive a more helpful warning message in the terminal?

from endless-sky.

When running with Nouveau from terminal I get:
Endless Sky requires OpenGL version 3.0 or higher.
Your OpenGL version is 2.1.2 NVIDIA 304.125, GLSL version 1.20 NVIDIA via Cg compiler.
Please update your graphics drivers.
terminate called without an active exception
Aborted (core dumped)

When running with Nouveau and double clicking the executable I get no error message and it just crashes.

It looks like I had not been quitting OpenAL properly, so it was crashing when the program quits. See if this is fixed in 896ce68.

from endless-sky.

The message is now as follows:
Endless Sky requires OpenGL version 3.0 or higher.
Your OpenGL version is 2.1.2 NVIDIA 304.125, GLSL version 1.20 NVIDIA via Cg compiler.
Please update your graphics drivers.

When double clicking the executable I still get no error message just a crash. Which I'm assuming is intended since you're only piping to cerr.

Also it seems that the Nouveau drivers do work I didn't realize I was actually using an older version of the proprietary drivers that had the issue.

from endless-sky.

I've modified the code to quit cleanly after printing that error message, instead of crashing (f534be9). Also, the error message should now be displayed in a message box in addition to the terminal, so it will be visible even if you launched the program by double-clicking it.

from endless-sky.

The message is now the same in console and in the message box.

This issue seems resolved, I'd close the ticket but I'm not sure if you're waiting to do an official tag before you close it or something.
