Bug Description

I think we should either fix it, or refuse the installation.

This is the mixxx.log

Since this particular problem appears to be with missing OpenGL libraries, is auto-switching to a non-GL waveform an acceptable solution? We might also want to pop up a warning so the user knows what's happening.

Daniel, does this crash still happen with an empty Mixxx config? (Do we default to a non-GL waveform?)

But the 64-bit Mixxx build does not trigger the same OpenGL failure log messages?

We build Qt 5 with "-opengl dynamic". https://doc.qt.io/qt-5/windows-requirements.html
"""
When configured with -opengl dynamic, neither Qt nor the applications built using qmake will link to the opengl32 (standard desktop OpenGL) or QtANGLE libraries. Instead, the appropriate library is chosen at runtime. By default, Qt will determine whether the system's opengl32.dll provides OpenGL 2 functions. If these are present, opengl32.dll is used, otherwise the ANGLE libraries (libEGL.dll and libGLESv2.dll) will be used. In case the ANGLE libraries are missing or initialization fails for some reason, an additional fallback is attempted by trying to load opengl32sw.dll. See below for details.
"""

This seems like a hint -- I wonder if the runtime loading logic in 32-bit Qt doesn't work when running on 64-bit Windows?

I believe we need to bundle libEGL.dll/libGLESv2.dll/libopengl32sw.dll with Mixxx.

libEGL.dll and libGLESv2.dll are present in our build environment ($ENV/Qt-5.11/bin/). I'm not sure where to get libopengl32sw.dll -- Qt hosts some pre-built ones:

Daniel -- can you try copying opengl32sw.dll from here:
https://download.qt.io/development_releases/prebuilt/llvmpipe/windows/
into the Mixxx folder w/ the other DLLs? Let's see if that lets us use software rendering at least.

If dynamic OpenGL is used, you additionally need to include the libraries required for ANGLE and software rendering. For ANGLE, both libEGL.dll and libGLESv2.dll from Qt's lib directory are required as well as the HLSL compiler from DirectX. The HLSL compiler library, d3dcompiler_XX.dll, where XX is the version number that ANGLE (libGLESv2) was linked against.

It's still a mystery why your 64-bit build works but the 32-bit doesn't. I think Qt's "dynamic" logic ("By default, Qt will determine whether the system's opengl32.dll provides OpenGL 2 functions.") must be failing for a 32-bit build of Qt on a 64-bit Windows system.

The opengl32sw.dll does the trick.

The crash is gone, but I have still the logfile spam and no moving waveforms with any option.

Interestingly the 64 bit Mixxx crashes now as well. I can remember I have experienced this crash before. Did we changed something recently or was this an issue caused by a Windows update?
I am pretty sure that I had a working Windows 64 Version when writing this bug: mixxx-2.2.0-alpha-pre-master-PR1632-git6492-release-x64.

The opengl32sw.dll helps here as well. I have now the software rendered waveforms and the QT GL types. For all others I can see only a moving beat grid.

@Daniel -- could you please try adding libEGL.dll, libGLESv2.dll, and d3dcompiler_47.dll to the 32-bit Mixxx installation folder without opengl32sw.dll? I'm wondering what will happen.

It does also not crash and the moving non GL waveforms are back like in the 64 bit version.
So the situation is slightly improved.
Here is the relevant logfile path:
