CMake和MinGW-”等；C编译器无法编译简单的测试程序；

我正在使用CMake和MinGW-w64位来构建。我在我的另一台电脑上使用了完全相同的设置和同一个编译器，它已经工作了。不知道怎么了

我的路径中有MinGW-w64垃圾箱。当我运行cmake并且没有指定编译器路径时，它会成功地生成MinGW makefile。但是，当我指定编译器时（我知道它可以工作，是从winlibs.com获得的），它会生成以下日志。我正在运行Windows 10

我认为这可能是CMake和MinGW Makefiles的错误。仍然不能完全确定它是什么

---

无论如何，我切换到忍者构建系统（），现在一切正常。

CMake似乎找不到

ar.exe

。能否显示您的

路径

的外观（ECHO%PATH%的输出）以及您使用的完整CMake命令行是什么？@BrechtSanders根据请求添加的。同样值得注意的是，它现在发生了两次，当时CMake告诉我它“找不到MinGW Makefiles的生成器”，而我清楚地知道你的构建在我的路径中。从路径中删除它并再次添加后，它两次都会再次工作，但对我来说这似乎很奇怪。。。不确定它是否相关。我倾向于在路径中更早地放置MinGW位置。例如，假设在您的示例中，“C:\Program Files（x86）\QuickTime\QTSystem\”包含与MinGW中同名的DLL，但一个是32位的，另一个是64位的？这有可能破坏一切。为什么要使用

-H

而不是

-S

来指定源位置？这不是问题的一部分，但是你有没有考虑过使用忍者而不是制造？这要快得多。我会早点把MinGW放进去，看看会发生什么！这些不是我输入的命令——它们是由用于VS代码的CMake工具扩展生成的！；）@不幸的是，这并没有解决问题。
