About downloading the installation package of QT 5.1
-
I can see there are 2 installation packages for qt5.1. One is "Qt 5.1.1 for Windows 64-bit (VS 2012 525 MB) (Info) ". The other is "Qt 5.1.1 for Windows 64-bit (VS 2012, OpenGL, 522 MB) (Info)". I guess the difference is the later has OpenGL development library involved. But the size of the packages is even smaller than the former one. Anybody can give some details on this??? Thanks So Much!!!

Qt uses OpenGL, but some users on Windows prefer DirectX. The download that does not have OpenGL in it shipps with ANGLE library, which translates OpenGL used by Qt into DirectX calls. This limits Qt to OpenGL ES 2 only.
If you and your users have OpenGL drivers on their PCs, use the OpenGL version.

Thanks for the tip! I have now my qt library worked . But another problem just came up that, I found it can not build the win32 app throuth x64 vsersion. Do I still need to install win32 version in addition to the installed x64 version to build the win32 version app?? Thanks

Hi and welcome to devnet,
Yes you do, Windows doesn't support multiple architectures in the same library.
