Можно ли использовать оболочку shed на Cygwin (execinfo.h отсутствует при установке libgc)?

Question

Я хотел попробовать скинуть кожу на Cygwin.

Установка скинов скина и libgc вроде бы нормально, но когда я пытался make скриптовый скрипт Python, он жалуется:

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

(полный список ниже)

Я проверил список установленных файлов на Cygwin для libgc, и он не включает execinfo.h

Означает ли это, что скиновая кожа не может быть использована на Cygwin?

Добавление отсутствующего файла execinfo.h ( загруженного из Интернета) к пути lib для make не помогает.

Ну, я не знаю никого, кто пытался использовать shedskin на Cygwin прежде, главным образом - я думаю - потому что в какой-то момент была некоторая (ограниченная) поддержка родной Windows.

Тем не менее, проблемы, с которыми вы сталкиваетесь, связаны с некоторыми известными ограничениями самого Cygwin, которые можно как-то смягчить, используя уровень совместимости, такой как Gnulib.

Это может исправить проблему asprintf, хотя это может быть просто отсутствие #include из stdio.h где-то.

В любом случае, я не могу гарантировать полную поддержку Cygwin, поскольку я вообще не пользуюсь Windows, но не стесняйтесь отправить электронное письмо по адресу [e-mail] - кто-то может захотеть глубже взглянуть на него. Если вы хотите внести некоторые исправления или документацию, ваша помощь очень приветствуется на GitHub.
