I made some digging: Building ossource_posix.cpp was disabled on win previously, not only this file, but WEBGL was disabled: features.prf: ... # WebGL support !contains(DEFINES, ENABLE_WEBGL=.) { contains(QT_CONFIG, opengl):!win32-*: DEFINES += ENABLE_WEBGL=1 } ... Before r122175 building of these files was in ENABLE_WEBGL _and_ contains(QT_CONFIG, opengl) | contains(QT_CONFIG, opengles2) blocks. After r122175 building of these files are in USE(3DGRAPHICS) block. I think the problem is that we try to build ossource_posix.cpp for Windows. If we really want to enable 3DGRAPHICS on Windows, we should use ossource_win.cpp instead of ossource_posix.cpp. Or we should disable 3DGRAPHICS on Windows.

I tried to use ossource_win.cpp instead of ossource_posix.cpp, but I got zillion different build errors later: In file included from /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/opengl/Extensions3DOpenGL.cpp:39:0: /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/OpenGLShims.h:59:43: error: 'GLsizeiptr' has not been declared /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/OpenGLShims.h:60:46: error: 'GLintptr' has not been declared /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/OpenGLShims.h:60:56: error: 'GLsizeiptr' has not been declared /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/OpenGLShims.h:79:92: error: 'GLchar' has not been declared /ramdisk/qt-windows-32bit-release/build/Source/WebCore/platform/graphics/OpenGLShims.h:80:93: error: 'GLchar' has not been declared make[4]: *** [obj/release/Extensions3DOpenGL.o] Error 1 make[4]: *** Waiting for unfinished jobs....
