c++ - 设置 mlpack 时找不到

Question

我尝试在cygwin中安装mlpack并且我已经安装了armadillo，但是我遇到了以下问题:

运行 cmake ../后我运行 make 命令，过程如下:

$ make

#include <execinfo.h>


编译中断。
src/mlpack/CMakeFiles/mlpack.dir/build.make:425: recipe for target 'src/mlpack/CMakeFiles/mlpack.dir/core/util/log.cpp.o' failed
make[2]: * [src/mlpack/CMakeFiles/mlpack.dir/core/util/log.cpp.o] Error 1

make[1]: * [src/mlpack/CMakeFiles/mlpack.dir/all] Error 2

make: * [all] Error 2

我不知道如何处理这个问题。

Cygwin 的 gnulib 不提供 execinfo.h，可能是由于与底层 (Windows) 系统的兼容性问题。

来自 gnulib documentation :

This header file is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS.

您可能想尝试像 CaptureStackBackTrace 这样的 WinAPI 函数相反。
