找不到<execinfo.h>當設置mlpack

Question

我試圖在Cygwin的安裝mlpack和我已經安裝了犰狳，但我遇到了以下問題：

運行cmake的後../我運行make命令，這裏是過程：

$ make

#include <execinfo.h> 


編譯中斷。 
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 

我不知道該如何處理這個問題。

Cygwin的gnulib不提供execinfo.h，可能是由於底層（Windows）系統的兼容性問題。

從gnulibdocumentation：

這個頭文件丟失在某些平臺上：蘋果OS X 10.3，FreeBSD的6.0，NetBSD的5.0，OpenBSD 3.8開始，Minix的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。

您可能想嘗試使用WinAPI功能，如CaptureStackBackTrace。
