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 ../后运行make命令，这是进程：

$ 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未提供execinfo.h，可能是由于与底层（Windows）系统的兼容性问题。

来自gnulib documentation：

在某些平台上缺少此头文件：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。

您可能希望尝试使用CaptureStackBackTrace之类的WinAPI函数。

安装mlpack </execinfo.h>时找不到<execinfo.h>
