Родные расширения ruby gem под msys2 не удалось
Я пытаюсь установить несколько гемов, некоторые из которых должны создавать собственные расширения.
Автоматически сгенерированный Makefile по неизвестной причине не работает должным образом. В результате возникает ошибка:
$ gem install ffi-yajl --verbose

Когда я захожу в эту папку и выполняю make вручную:
$ make
make: *** No rule to make target '/C/msys64/mingw64/include/ruby-2.3.0/ruby.h', needed by 'encoder.o'. Stop.
Рассматривая проблему еще более внимательно:
$ ls -l /C/msys64/mingw64/include/ruby-2.3.0/ruby.h
-rw-r--r-- 1 User None 868 Jul 11 2012 /C/msys64/mingw64/include/ruby-2.3.0/ruby.h
Если я немного изменю Makefile (уберу зависимость от заголовков для объектов), произойдет очевидное:
$ make
compiling encoder.c
encoder.c:1:18: fatal error: ruby.h: No such file or directory
compilation terminated.
Makefile:238: recipe for target 'encoder.o' failed
make: *** [encoder.o] Error 1
выполнение команд вручную (генерируется make -n) не дает ошибок и успешно компилируется. К сожалению, я не могу использовать этот хакер для создания драгоценного камня.
Тогда возникает вопрос: почему система не находит заголовок при запуске make, но находит его при непосредственном использовании gcc? Что мне нужно изменить?
