我想在 cygwin 上尝试脱皮。
安装脱皮和 libgc 似乎没问题，但当我尝试make脱皮皮肤的Python脚本时，它会抱怨：
/usr/lib/python2.7/site-packages/shedskin/lib/builtin.hpp:31:22: fatal error: execinfo.h: No such file or directory
compilation terminated.
（下面的完整列表）
我检查了list of installed files on Cygwin for libgc，但它不包含 execinfo.h
这是否意味着脱落的皮肤不能用于 Cygwin ？

好吧，我并不知道有人试图在Cygwin上使用棚子 之前，主要 - 我认为 - 因为有一些（有限） 在某些时候支持本机Windows。
但是，你所遇到的问题还有一些已知的局限性 Cygwin本身，你可以通过使用一个缓解 兼容层，例如Gnulib。
这可能会解决asprintf问题as well，尽管它可能只是一个问题
在某处#include丢失了stdio.h。
无论如何，我无法保证完全支持Cygwin，因为我没有使用 Windows本身，但随时发送电子邮件 shedskin-discuss@googlegroups.com - 有人可能想拥有 深入了解它。如果你想提供一些修复或 文档，非常欢迎您的帮助on GitHub。
