Description
While compiling qnanopainter we received "undefined reference" errors with Qt 5.12.x MinGW whereas compilation worked fine on Qt 5.9.x MinGW.
This is a snippet of the errors, all related to the lib "libGLESv2d":
libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x12b): undefined reference to `_imp__glDeleteTextures@8' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x1b4): undefined reference to `glDeleteShader@4' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x1d5): undefined reference to `glDeleteBuffers@8' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x1e5): undefined reference to `glDeleteShader@4' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x1f5): undefined reference to `glDeleteProgram@4' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x988): undefined reference to `_imp__glBindTexture@8' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x9a0): undefined reference to `_imp__glPixelStorei@8' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x9fc): undefined reference to `_imp__glTexSubImage2D@36' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0xa43): undefined reference to `_imp__glBindTexture@8' libqnanopainter.a(qnanobackendgles2.cpp.o):qnanobackendgles2.cpp:(.text+0x1361): undefined reference to `_imp__glDeleteTextures@8'
As it turned out, the "def" files for "libGLESv2d" seems to be off in Qt 5.12.x. The 32 bit def file duplicates the 64 bit one lacking the correct function namings. E.g. "glBindTexture@8" is just "glBindTexture" and so on. Def file from Qt 5.9.x contains the correct naming, spotted in the errors above.
