some shader crap

[nonetrix]

I ran the program and it spammed this "There was an error initializing the shaders:" and then said
"thread 'main' has overflowed its stack
fatal runtime error: stack overflow
Aborted (core dumped)"

System

OS: Linux/BSD/macOS/Windows manjaro linux
system: core 2 duo with integrated graphics
Version: alacritty --version output 0.4.1
Linux/BSD: X11 i3
Windows: WinPTY/ConPTY same error

Logs

it crashed the paste bin website somehow sorry

Does your GPU support OpenGL 3.2 or higher?

[nonetrix]

How can I check?

[cole-h]

On Linux, you can run glxinfo | grep "OpenGL version".

Same here. Just installed it on a Dell Inspiron 6400 with Radeon Mobility x1400 graphics running Ubuntu 19.10 and X. No, the GPU doesn't support OpenGL 3.2 or higher: OpenGL version string: 2.1 Mesa 19.2.8. However, this is terrible error handling. The application ought to detect the error and quit, not overflow its stack. Also it ought to tell me why, like that it requires OpenGL 3.2 or higher and I only have 2.1.

However, this is terrible error handling. The application ought to detect the error and quit, not overflow its stack.

This bug of error handling is already fixed on master ( #3239 ) and was accidentally introduced during some refactoring. So you can compile master and get a proper error if you want.

I'll be sure to check as soon as I can

Probably wouldn't fix it but Vulkan support would be really cool

Hopefully I can compile it for arm when my pinebook pro comes

GPUs that don't even support OpenGL 3.2+ which is already ancient are much less likely to support Vulkan. I'm not aware of any that do.

Sounds like this is a duplicate of #128 though.

[kchibisov]

Well, it depends, but for example the one on Pinebook pro you can use Vulkan 1.0 and other GL ES things, however it can't run OpenGL 3.3 app like alacritty.

Look at t860

OpenGL 3.2 might be sufficient, though I could be wrong since GLSL 330 is only supported with OpenGL 3.3 I think.
