# define always_inline __attribute__((always_inline))
被包括(從另一個包含的文件),並與gcc 4.9抱怨:
inc/compiler.h:98:40: error: '__always_inline__' was not declared in this scope
# define always_inline __attribute__((always_inline))
^
奇怪的是,相同的標頭(編譯器。 h)被包含在另一個編譯成功的源文件中。有任何想法嗎? 編輯:我只是確保always_inline
未預定義。 FYI:

你在定義宏的行上得到了這個錯誤信息? –
@凱瑟湯普森是的。 – Walter
如果你編譯一個只包含那一行的'foo.c'文件,會發生什麼?是否有可能在該行上有一些有趣的人物?前一行的尾部反斜槓? –
