About This Repository

This repository contains some changes to Qt 4.8.7, mostly to QMake, to make it easier to build Qt with the following Visual Studio versions:

• Visual Studio 2010
• Visual Studio 2012
• Visual Studio 2013
• Visual Studio 2015
• Visual Studio 2017
• Visual Studio 2019

Updates to Qt

Updated tools/configure/configure.pro and tools/configure/configureapp.cpp to recognize win32-msvc2019 as a valid QMAKESPEC for Windows.

Updates to QMake

Added support for QMake variable MSVC_VERSION. This obviates the need to use registry and PATH to deduce the version of Visual Studio for which the .vcxproj file is being generated. This must be defined for QMake to work properly. The qmake.conf files under the following folders have been updated to define it appropriately.

• mkspecs/win32-msvc2010
• mkspecs/win32-msvc2012
• mkspecs/win32-msvc2013
• mkspecs/win32-msvc2015
• mkspecs/win32-msvc2017
• mkspecs/win32-msvc2019

Added support for QMake variable MSVC_TARGET_ARCH. This obviates the need to deduce the target architecture from the version of Visual Studio found in PATH. This is an optional variable. If this is not defined, the target architecture defaults to Win32. The qmake.conf files under the following folders have been updated to define it to x64 by default.

• mkspecs/win32-msvc2010
• mkspecs/win32-msvc2012
• mkspecs/win32-msvc2013
• mkspecs/win32-msvc2015
• mkspecs/win32-msvc2017
• mkspecs/win32-msvc2019

Added support for QMake variable VCPROJ_TARGET_PLATFORM_VERSION. This variable is optional. This is useful when there are multiple target platforms but the user want to build against a specific one. If it is defined, its value is output in the Global PropertyGroup. E.g.

 <WindowsTargetPlatformVersion>10.0.14393.0</WindowsTargetPlatformVersion>
