能够解决此问题这个问题。

Was able to get a fix around this problem.

为用户环境变量Path （Was和gcc / g ++（由Mingw / Ansys安装）的正确路径添加了不允许编辑系统变量路径）。

Added the correct paths for two exes - make and gcc/g++ (installed by Mingw/Ansys) to the User environment variable Path (Was not allowed to edit System variable Path).

但是将这些路径添加到用户环境变量Path 中也有助于解决此问题。现在，Eclipse CDT可以很好地构建和执行代码。

But adding these paths to User environment variable Path also helped to resolve this. Now Eclipse CDT built and executed the code fine.
