aclocal 命令

命令示例

说明

aclocal is part of the GNU Automake build system. It generates an aclocal.m4 file by scanning configure.ac (or configure.in) for macro invocations and collecting the required macro definitions from installed .m4 files. The generated aclocal.m4 file contains all the M4 macros needed by autoconf to process configure.ac. This tool is essential for projects using the GNU build system (autotools) as it bridges Automake and Autoconf.
