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

问题描述

我正在尝试在 windows 下的 eclipse 中构建一个 makefile 项目，但构建失败（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”，一切都会运行得很好。为了弄清楚为什么在 Eclipse 中构建不起作用，我现在试图找出在终端和 Eclipse 中使用 make 之间的区别。在构建失败之前，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，在这两种情况下都调用了 make 但结果不同。Makefile 在这两种情况下也是相同的。什么可能导致这种情况？

解决方案

在 eclipse 中调用和在 msys2 终端中调用的区别make在于它运行在不同的环境中。为了确保我使用这两种方法获得相同的结果，我必须确保我的 Windows PATH 包含正确的条目。为了找出我必须添加到 PATH 的条目，我检查了config.log失败案例和成功案例。

此外，我必须以管理员身份运行 eclipse，因为它没有创建临时文件的权限。
