Hi all. Maybe I'm wrong - that's not exactly my cup of tea here - but I've noticed something that feels off to me. The def file <https://code.qt.io/cgit/qt/qtbase.git/tree/src/3rdparty/angle/src/libGLESv2/libGLESv2_mingw32.def?h=5.9.8> included in Qt 5.9.x for the exported functions seems to correctly match the undefined references that I reported in the original email. Things like "glBindTexture@8" or "glDeleteTextures@8" are indeed there and there is no undefined reference. Instead, the corresponding file <https://code.qt.io/cgit/qt/qtbase.git/tree/src/3rdparty/angle/src/libGLESv2/libGLESv2d_mingw32.def?h=5.12.3> in Qt 5.12.x seems to export different names and it matches exactly the non ming32 <https://code.qt.io/cgit/qt/qtbase.git/tree/src/3rdparty/angle/src/libGLESv2/libGLESv2d.def?h=5.12.3> one.
Is that correct? Thanks, F.
