Autotools 구성하기

$ autoreconf -i
aclocal: warning: couldn't open directory 'm4': No such file or directory
libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'build-aux'.
libtoolize: copying file 'build-aux/ltmain.sh'

configure.ac:10: installing 'build-aux/ar-lib'
configure.ac:10: installing 'build-aux/compile'
configure.ac:30: installing 'build-aux/config.guess'

configure.ac:5: installing 'build-aux/install-sh'
configure.ac:5: installing 'build-aux/missing'
src/Makefile.am: installing 'build-aux/depcomp'

빌드에 필요한 스크립트들이 설치된다.
