是否可以在Cygwin上使用shed skin（libgc安装时缺少execinfo.h）？

Question

我想试着在cygwin上脱皮。你知道吗

安装shed skin和libgc似乎还可以，但是当我尝试makeshed skin Python脚本时，它抱怨：

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

（完整列表如下）

我检查了list of installed files on Cygwin for libgc，它不包括execinfo.h

这是否意味着蜕皮不能用于Cygwin？

编辑1：

将缺少的execinfo.h（downloaded来自internet）添加到make的lib路径没有帮助。你知道吗

嗯，我不知道有人试图用舍德斯金来对付西格温 以前，我想主要是因为 在某种程度上支持本机窗口。你知道吗

尽管如此，你所遇到的问题仍然存在一些已知的局限性 Cygwin本身，您可以通过使用 兼容层，如Gnulib。你知道吗

这可能会解决asprintf问题as well，尽管这可能只是一个问题 在某处缺少#include的stdio.h。你知道吗

无论如何，我不能保证完全支持Cygwin，因为我没有使用 我自己也可以，不过可以发邮件给我 shedskin-discuse@googlegroups.com-可能有人想要一个 再仔细看看。如果你想贡献一些修复或者 文档，非常欢迎您的帮助on GitHub。你知道吗
