安装mlpack时找不到<execinfo.h>

Question

我试图在cygwin中安装mlpack，并且已经安装了armadillo，但遇到了以下问题：

在运行cmake ../我运行make命令之后，下面是处理过程：

$ 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 文档

在一些平台上缺少此头文件:MacOSX10.3、FreeBSD 6.0、NetBSD 5.0、OpenBSD 3.8、Minix 3.1.8、AIX5.1、HP-UX11、IRIX 6.5、OSF/1.5.1、Solaris 10、Cygwin、mingw、MSVC 9、Interix3.5、BeOS。

您可能希望尝试类似于WinAPI的CaptureStackBackTrace函数。
