Crash on shader compilation: "GLSL 4.30 is not supported."

As previous issue was fixed (or workarounded), I was able to get access to osp-magnum command line, but again - unable to play. Here is my console log:

Choose a test universe:

• simple - Simple test planet and vehicles (default)
• moon - Simulate size and gravity of real world moon

Start Application:

• flight - Create an ActiveArea and start Magnum

Other things to type:

• list_uni - List Satellites in the universe
• list_ent - List Entities in active scene
• list_upd - List Update order from active scene
• help - Show this again
• exit - Deallocate everything and return memory to OS

Is GLSL 4.30 not backward compatibile or so?
Edit: I checked glxinfo output, but I'm not sure what it really means, seems to be ambiguous:

Hmm, I think we should reconsider compatibility. Many computers are still on OpenGL 3.3 today.

There's a quick workaround here, but exhaust plumes will not work:

Comment out line 102 in src/test_application/flight.cpp

auto &sysExhaustPlume   = scene.dynamic_system_create<osp::active::SysExhaustPlume>();

This will disable exhaust plumes entirely.

Ok, so it's says that MY CARD doesnt support GLSL 4.30, not the application. Now it's logical. Yes, my both GC are rather old.
But disabling exhaust plumes didnt help. Here is output from Gnu Debugger:

Thread 2 "osp-magnum" received signal SIGABRT, Aborted.

It seems that main renderer is incompatibile with OpenGL 3.3.

Comment out SysDebugRender.cpp line 56:

glResources.add<PlumeShader>("plume_shader");

which is where shaders are currently (temporarily) initialized. My shader doesn't actually use any fancy features that aren't supported by 3.3, so I can introduce that backwards compatibility in the future.

Thanks for being our guinea pig by the way, we've not had an outsider build our codebase before so this is all very useful information.

[pirogronian]

This works. Thank You again. But there is another few issues to come... 😉
