[Development] Building Qt with dynamic OpenGL on MinGW broken

[Julius Bullinger]

Hello,

because of QTBUG-52487, there's currently no straight-forward way to build an OpenGL-dynamic QT 5.7 with MinGW on Windows. There's a patch attached to the bug report, but it's not on Gerrit (and the author hasn't responded to the request to push it to Gerrit).

May I propose that somebody else takes the patch and pushes it to Gerrit for a proper review? 

Thanks and best regards,
Julius
