在Eclipse中调用“ make”和在终端中调用“ make”有什么区别？

如何解决在Eclipse中调用“ make”和在终端中调用“ make”有什么区别？

我正在尝试在Windows下的Eclipse中构建一个makefile项目，但是构建失败（“项目”>“构建项目”）。但是，如果我导航到msys2终端中的构建目录并调用“ make”，则一切运行正常。 为了弄清楚为什么无法在eclipse中进行构建，我现在试图找出在终端和eclipse中使用make之间的区别。 直到构建失败为止，eclipse的控制台输出与msys2终端中的输出相同：

这是eclipse中的控制台输出：

这是msys2终端中的输出：

据我所见，在两种情况下都调用了make，但结果不同。在这两种情况下，Makefile也相同。 是什么原因造成的？

解决方法

在eclipse和msys2终端中调用make的区别在于，它在不同的环境中运行。为了确保两种方法都能获得相同的结果，我必须确保Windows PATH包含正确的条目。为了找出必须添加到PATH的条目，我检查了config.log的失败案例和成功案例。

另外，我还必须以管理员身份运行Eclipse，因为它没有创建临时文件的特权。
