在Cygwin中安装xgboost时缺少execinfo.h

Question

我按照以下教程在Cygwin64中安装xgboost python包:

但是当在dmlc-core目录中执行make时,我收到以下错误:

为什么我收到此错误？如果您需要更多信息,请告诉我.

Answer 1

你可以#undef DMLC_LOG_STACK_TRACE在第45行的定义之后把它放在这里.请参阅本要点中的示例.

execinfo.h仅适用于Linux,但在此项目中,它仅用于在Linux上调试和打印堆栈跟踪.有一张支票在他们的代码库MinGW的,不知道为什么它没有被定义(他们已经禁用它,看到这个PR).

您应该尝试更改这些行并make再次运行.
