cannot open output file c__.exe: Permission denied

问题描述

今天运行调试C++程序抛出了cannot open output file c__.exe: Permission denied提示信息，详细信息如下：

d:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot open output file c__.exe: Permission denied
collect2.exe: error: ld returned 1 exit status
mingw32-make.exe[3]: *** [c__.exe] Error 1
CMakeFiles\c__.dir\build.make:121: recipe for target 'c__.exe' failed
mingw32-make.exe[2]: *** [CMakeFiles/c__.dir/all] Error 2
CMakeFiles\Makefile2:66: recipe for target 'CMakeFiles/c__.dir/all' failed
CMakeFiles\Makefile2:78: recipe for target 'CMakeFiles/c__.dir/rule' failed
mingw32-make.exe[1]: *** [CMakeFiles/c__.dir/rule] Error 2
mingw32-make.exe: *** [c__] Error 2
Makefile:117: recipe for target 'c__' failed

原因

• 通过查资料发现这个挺简单，运行的程序没有结束，又运行另一个程序。
• 还有可能同一个工程下面有个两个入口函数main，删除一个就OK了。

解决办法

我使用的工具是IDE，在run那一栏点击红色正方形按钮
