VS2010 编译 QT4.8.7 x64

1 下载qt4.8.7源代码，解压到合适位置(如本文为d:\qt\4.8.7)

2 设置环境变量：

set QMAKESPEC=win32-msvc2010
set QTDIR=d:\qt\4.8.7

3 修改配置文件：

修改\mkspecs\win32-msvc2010\qmake.conf

将QMAKE_CFLAGS_RELEASE的O2改为O1

或

安装补丁https://support.microsoft.com/en-us/kb/2280741或https://www.microsoft.com/en-us/download/details.aspx?id=23691

否则编译出的64位程序不能启动！

4 登录vs2010 x64 win64命令行工具

5 输入命令：

>> cd %QTDIR%

>> configure -shared -debug-and-release -confirm-license -opensource -platform win32-msvc2010 -no-webkit -no-plugin-manifests -qt-zlib -qt-libpng -qt-libjpeg -vcproj -mmx -3dnow -sse -sse2 -mp -opengl desktop -fast -no-qt3support -nomake examples -nomake demos -nomake tests –largefile

>> jom.exe -j 4

>> jom.exe clean 

“jom is a clone of nmake to support the execution of multiple independent commands in parallel.”
