问题描述
我在使用Automake时遇到以下错误。我知道您可以将AUTOMAKE_OPTIONS=subdir-Objects"放在Makefile.am的顶部。但我如何为所有文件设置此行为，这样我就不需要逐个执行此操作？
Makefile.am:454: warning: source file 'libs/esl/src/esl_threadmutex.c' is in a subdirectory,
Makefile.am:454: but option 'subdir-objects' is disabled

推荐答案
不是"逐个"添加的，因为AUTOMAKE_OPTIONS适用于整个项目。这也是它在未来应该被使用的唯一方式，因此有警告；目前它是选择加入的。
您也可以使用AM_INIT_AUTOMAKE在configure.ac中设置此选项，请参阅Autotools Mythbuster(完全公开：我是作者)以了解您可以使用的全套汽车制作选项。
