链接器C编译错误

Question

我正在尝试编译一些C代码并遇到错误：

信息：Internal Builder用于构建gcc -o Test2.exe“ src \\ Test2.o” c：/ mingw / bin /../ lib / gcc / mingw32 / 4.8.1 /../../../ ../mingw32/bin/ld.exe：无法打开输出文件Test2.exe：权限被拒绝collect2.exe：错误：ld返回1退出状态

我知道这个错误通常在整个Internet上都会问到，但是在阅读了几种解决方案之后，它们似乎对于每个代码示例都是唯一的。 我已经确定这是链接程序的问题，但是我对C不够熟悉，因此不知道如何缩小它的范围。

这是我的代码：

在某一时刻，我注释掉了所有内容以试图找出错误的原因，但是即使我只打印“ Vectors”并在主窗口中返回0时，我也遇到了它。 它说无法打开Test2.exe，所以我找到了该文件的存在并尝试删除它。 但是，它说“ Test2.exe不能删除，因为它已在Test2.exe中打开”，我发现它令人沮丧地令人发笑（或令人沮丧地令人沮丧）。

任何帮助表示赞赏。 供参考，我将Windows 8.1和Eclipse与MinGW结合使用
