使用 Cygwin 从 FreeBSD 到 Windows

Question

我有一个在 FreeBSD 中开发的 C 和 Fortran 代码，我想在我的 Windows 系统上运行它。所以我使用 Cygwin 作为替代方案。 除了代码之外，还有一个 Makefile，我尝试过并在 Makefile 中进行了一些更改。现在 makefile 运行完美，但在 makefile 中的某个时刻，它给了我大量与 Fortran 和 Lapack 库相关的错误。 我检查了我的库，它们都存在于我的系统中。 在参考了论坛的相关问题后，我尝试并使用了许多选项。但这没有用。 我对这个 Makefile 东西很陌生。 请帮我解决这些错误。

下面是 Makefile

您从链接器标志中删除了所有外部库。将 STD_LIB 中的库添加到您的命令中
