在 Cygwin 中安装 xgboost 时缺少 execinfo.h

Question

我已按照以下教程在 Cygwin64 中安装 xgboost python 包：

但是在 dmlc-core 目录中执行 make 时出现以下错误：

为什么会出现此错误？如果您需要更多信息，请告诉我。

Answer 1

您可以在第 45 行 here 的定义后面加上 #undef DMLC_LOG_STACK_TRACE。请参阅此gist 中的示例。

execinfo.h 仅在 Linux 上可用，但在此项目中，它仅用于在 Linux 上调试和打印堆栈跟踪。在他们的代码库中有 a check 用于 Mingw，不知道为什么没有定义它（他们已经禁用它，请参见 PR）。

您应该尝试更改这些行并再次运行make。
