From e0c0e83fd5534b24f18d5e02a453182df54933e0 Mon Sep 17 00:00:00 2001 From: Jason Barron Date: Mon, 15 Oct 2012 14:16:51 +0200 Subject: Add ANGLE as a 3rdparty library to Qt. ANGLE is a component that implements the OpenGL ES 2.0 API on top of DirectX 9. See the following for more info: http://code.google.com/p/angleproject/ ANGLE is now the default configuration on Windows. If you want to use desktop OpenGL, you should build Qt with the following configure options: -opengl desktop To configure Qt to use another OpenGL ES 2 implementation, you should use: -opengl es2 -no-angle Task-number: QTBUG-24207 Change-Id: Iefcbeaa37ed920f431729749ab8333b248fe5134 Reviewed-by: Friedemann Kleint --- src/3rdparty/angle/src/compiler/VariablePacker.h | 41 ++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 src/3rdparty/angle/src/compiler/VariablePacker.h (limited to 'src/3rdparty/angle/src/compiler/VariablePacker.h') diff --git a/src/3rdparty/angle/src/compiler/VariablePacker.h b/src/3rdparty/angle/src/compiler/VariablePacker.h new file mode 100644 index 0000000000..8987066cc3 --- /dev/null +++ b/src/3rdparty/angle/src/compiler/VariablePacker.h @@ -0,0 +1,41 @@ +// +// Copyright (c) 2002-2012 The ANGLE Project Authors.
