This error message means that your graphics drivers do not support OpenGL 3.0. Either upgrade them, or use SolveSpace 2.x.

not everyone can upgrade (by FOSS Advocate)

Hi, just to report that I too had the " Unable to create a GL context " problem.

Linux Mint 18 ( based on Ubuntu 16.04 ) is the OS, which actually runs wonderfully, but this old Intel hardware is capped at OpenGL v2.

After wrestling with Git and GitHub eventually I managed to build it locally from the "2.x" branch, and it worked enough to follow the first extremely helpful, highly recommended Tutorial http://solvespace.com/bracket.pl for which many thanks Devs!

So, don't give up Andrey, it might still be possible to get something working. I posted my actual steps on another thread : http://solvespace.com/forum.pl?action=viewthread&parent=1830

And to the Developers, please don't abandon those of us trapped on old hardware.

It would be a shame to have only just discovered this exciting project and immediately find we're being flipped the digit, especially if we're keen and able to help with the testing and feedback.

Thanks

The 2.x branch is still supported. In fact, the 3.x branch has not yet seen a release and probably should not be generally used yet.

In any case, there are performance (rendering complex designs quickly), quality (rendering certain features, such as hidden lines, legibly) and maintenance (keeping a single renderer base on every supported platform) reasons to migrate to OpenGL 3. I cannot support old hardware forever and it is my decision as a maintainer to migrate going forward.

Also, no one is "flipping a digit" to you. It is not fair to inflict a disproportionate workload on the few developers of SolveSpace so that a few people with extremely old hardware can avoid upgrading. You do not want to bear this cost, why should I?

You're upset. That was not the intention. :o(

Clearly poor wording on my part and for that I offer humble apologies.

The sorely-disappointed underlying sentiment is a rollover emotion borne of discovering yet another interesting FOSS project (the fourth in a row) just as it's on the cusp of migrating and excluding what we have available.

> "You do not want to bear this cost"

We're not all wealthy Americans on this planet.

It's far from a case of "not wanting to."

I still want to express respect and gratitude, and wish you and the project well. :o)

Namaste

Maybe we just need to make it more obvious that non-developers who nonetheless build SolveSpace from source should be running 2.x, regardless of the graphics drivers available to them? That (a) stops people from running unstable software, and (b) postpones the GL version issue until even fewer people would encounter it.
