The settings which I guess break the build are USE=gles2 for Qt:

# equery u qtopengl
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for dev-qt/qtopengl-5.12.4:
 U I
 - - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
 + + gles2 : Use GLES 2.0 or later instead of full OpenGL
 - - test  : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

[Comment 1 Tiziano Müller (RETIRED) 2019-08-20 11:22:00 UTC]

It seems that VirtualBox is bundling a very old (2007) version of glext.h, because mesa-19.1.4 has the `const GLchar *const*string` in both GL/glext.h and GLES3/gl32.h for PFNGLSHADERSOURCEPROC, and there it was added in 2013.
I assume that when building with qtgui[gles2] MESA's `gl32.h` leaks into the include-chain for some reason, while it doesn't when using GL.

Created attachment 587606 [details, diff]
minimal patch to make it build

adding a minimal patch which makes it build by updating the definition to the one found in `glext.h` from 2013
