问题描述
我已安装 Qt开源4.8.3 Windows上的库 Windows 8 Pro x64 ， Qt Creator 2.6.0 和 MingW 4.4.0 手动。从Qt Creator我有安装工具包和编译器。我打开模拟时钟示例自带Qt Creator并重建项目。编译器发出以下错误。
I've installed Qt Open source 4.8.3 library for Windows on Windows 8 Pro x64, Qt Creator 2.6.0 and MingW 4.4.0 manually. From Qt Creator I've setup kits and compilers. I opened the analog clock example comes along with Qt Creator and rebuild the project. The following error are emitted by the compiler.
Running steps for project analogclock...

Error while building/deploying project analogclock (target: Desktop)
When executing step 'Make'
我已验证 C：/Qt/4.8.3/examples/widgets/analogclock/analogclock。 cpp 存在。
为什么会出现此错误，如何解决？
Why is this error occurring and how can i fix it?
推荐答案
似乎你的g ++安装不干净，所以编译器不能启动（这也是你在评论中说的）。尝试重新安装，然后你可以尝试构建一个hello world程序来验证是否可以运行g ++。此外，请验证您的PATH变量已正确配置为mingw。
It seems your installation of g++ is not clean, so the compiler cannot be launched (this is also what you've said in the comments). Try reinstall, and then you can try to build a hello world program to verify whether you can run g++. Also, please verify that your PATH variable is properly configured for mingw.
