ImGui_ImplOpenGL3_CreateDeviceObjects failed to compile verted/fragment shader & link shader program

[jmoraispk]

When executing a DearPyGui script, which uses ImGui, I got this error, and it seems related with ImGui.

Any idea of what might be happening?

ERROR: ImGui_ImplOpenGL3_CreateDeviceObjects: failed to compile vertex shader!

The wording of the shader compilation error message changed back in June 2021 (specifically during 70c6038) so the version of Dear ImGui you're using is quite old.

Additionally this version is prior to the embedded loader change, which means OpenGL is not automatically loaded on your behalf. Loader failures manifest themselves in different ways, so it's hard to say for sure if it's your problem here.

You should probably just update to a newer version of the package to rule out this problem entirely.

Thanks @PathogenDavid. The version of ImGUI I'm using was packaged jointly with DearPyGUI, so I'll talk with them.
