编译Qt Creator 工程

//build
1.下载Qt Creator源码
2. 　2.下载Qt库源码，下载地址http://download.qt.io/archive/qt/5.6/5.6.1/single/，下载 qt-everywhere-opensource-src-5.6.1.zip。
3.建立空目录build用于保存编译结果，这里为Qt5.6.1\Tools\build，即与自带的Qt Creator放在一个目录下，没什么特殊意义，放哪都行。将Qt Creator源码也放在Tools目录下，方便编译。

编译：

1.在开始菜单Qt5.6.1中打开Qt 5.6 for Desktop (MinGW 4.9.2 32 bit)，使用cd命令行更改到build目录下。

2.执行qmake命令。qmake ../qt-creator-opensource-src-4.0.1/qtcreator.pro -r -spec win32-g++ "CONFIG+=release" "QT_PRIVATE_HEADERS=F:\Qt\Qt5.6.1\5.6\mingw49_32\include"，这时build目录下会生成MakeFile文件。

   qmake ../qt-creator-opensource-src-4.3.1/qtcreator.pro -r -spec win32-g++ "CONFIG+=debug" "QT_PRIVATE_HEADERS=F:\Qt\Qt5.6.1\5.6\mingw49_32\include"

   mingw32-make debug

3.开始编译。执行命令mingw32-make release。编译过程比较长。编译完成的可执行文件在build/bin中，像其他MinGW编译的release执行档一样，需要相应的dll支持才可运行。
