可以在Cygwin ( libgc安装时缺少execinfo.h)使用脱落的皮肤吗？

Question

我想试着在雪佛兰身上脱皮。

shed皮肤和libgc的安装似乎还可以，但是当我尝试make这个带棚皮的Python脚本时，它抱怨道：

/usr/lib/python2.7/site-packages/shedskin/lib/builtin.hpp:31:22: fatal error: execinfo.h: No such file or directory
compilation terminated.

(详见下文)

我检查了libgc在Cygwin上安装的文件列表，它不包括execinfo.h

Cygwin 是否意味着脱皮不能在上使用

编辑1：

将缺少的execinfo.h (来自互联网的下载)添加到make的lib路径中没有帮助。

嗯，我不知道以前有人试图在Cygwin上使用shedskin，我认为主要是因为在某个时候对本机Windows有一些(有限的)支持。

但是，Cygwin本身也存在一些已知的限制，您可以通过使用兼容性层(如格努利卜 )来减轻这些限制。

这可能解决了asprintf问题也是，尽管它可能只是某个地方缺少的#include of stdio.h。

无论如何，我不能保证对Cygwin的完全支持，因为我自己根本不使用Windows，但是可以随意发送电子邮件给shedskin-讨论@googlegroups.com--也许有人想更深入地了解它。如果您想提供一些修复或文档，您的帮助是非常欢迎的论GitHub。
