刚开始的时候图省事,直接下载了1.3G的 Qt SDK 完整开发环境下来安装,结果就出问题了:学习开发自定义控件时安装不上,提示:The plugin' 'uses incompatible Qt library.Expected build key"windows msve release full-config",got"windows mingw debug"
关于这个错误,官方说:
The version of QT Creator shipped with the QT SDK Open Source version for windows is build using Visual Studio, whereas the SDK is build with and supports g++ (MinGW). This doesn’t cause too many problems, but it totally defeats building and installing QT Designer
plugins into QT Creator. The error message is:
也就是说,QtCreator是用Visual Studio编译的,但QtCreator的编译器是MinGW,编译出来的控件自然就加载不到QtCreator上了。
网上说解决方法有三种:
1) Build QT Creator from source with MinGW
2) Build the plugin with Visual Studio
3) Build QT Creator with build key checking turned off.
我就选择了第一种:自己编译安装QtCreator。
1、下载
MinGW-gcc440_1.zip
qt-win-opensource-4.8.2-mingw.exe

2、把MinGW-gcc440_1.zip解压到C盘,然后安装qt-win-opensource-4.8.2-mingw.exe,接着把 C:\mingw\bin 添加到系统环境变量。
3、下载QtCreator的源文件包qt-creator-2.3.0-src.zip,把压缩包里面的东西都解压取文件夹D:\qt-creator,此时的目录结构应该是D:\qt-creator\qtcreator.pro
4、编译安装QtCreator:新建一个目录 D:\QtCreator(注意这里跟前面的qt-creator不同),再把以下内容复制到一个新建的批处理文件
- qmake "CONFIG+=release"
- make
- nmake INSTALL_ROOT="D:\QtCreator" install
把批处理文件保存到 D:\qt-creator,双击运行。
5、批处理成功执行后,把 D:\qt-creator\bin 里面的dll文件复制到 D:\QtCreator\bin ,如果可以双击运行 D:\QtCreator\qtcreator.exe,说明QtCreator安装编译成功!
接下来还要对开发环境进行相应的设置,留到下一章再说...
