java - 构建 OpenJDK 15 时如何在 cygwin 上修复“配置：错误：C 编译器无法创建可执行文件”

Question

我正在尝试在 Windows 上构建 OpenJDK 15。我正在运行 Windows 10、最新的 Cygwin 和 Visual Studio 2019。我遵循了这个构建指令，配置脚本告诉我我的编译器无法创建可执行文件。

我不知道我在哪里搞砸了。我使用所需的 Cygwin 包和 Microsoft Visual Studio 2019 正确设置了我的构建环境。与我所做的构建指令的唯一偏差是以管理员身份运行 Cygwin shell。另外，我同时安装了 Cygwin 和 MinGW，这会是问题吗？

编辑：这是我的config.log
