Automake的使用

进入到你的源码目录

$ cd src
$ ls
main.c
cat main.c
# 代码如下：
#include <stdio.h>

int main(int argc, char** argv){

    printf("Hello, Auto Makefile!\n");
    return 0;

}

开始使用Automake了

执行autoscan

$ autoscan
$ ls
autoscan.log    configure.scan  main.c

复制configure.scan为configure.ac(以前为configure.in)

$ cp configure.scan configure.ac

编辑configure.ac或configure.in文件

#                                               -*- Autoconf -*-
#Process this file with autoconf to produce a configure script.
AC_PREREQ([2.69])
#包名(最终可执行文件)、版本号、联系地址
AC_INIT(main, 1.0, 1710308677@qq,com)
AC_CONFIG_SRCDIR([main.c])
AC_CONFIG_HEADERS([config.h])
#加这一行：包名、版本号与上面保持一致configure.in写法
#AM_INIT_AUTOMAKE(main,1.0)
#configure.ac写法
#加这两行行：包名、版本号与上面保持一致configure.in写法
AC_CONFIG_SRCDIR([main.c])
AM_INIT_AUTOMAKE
#Checks for programs.
AC_PROG_CC
#Checks for libraries.
#Checks for header files.
#Checks for typedefs, structures, and compiler characteristics.
#Checks for library functions.
#加这一行表示要生产的Makefile这个文件
AC_OUTPUT([Makefile])

执行aclocal

$ aclocal
$ ls
aclocal.m4  autoscan.log    configure.scan
autom4te.cache  configure.in    main.c

执行autoconf

$ autoconf
$ ls
aclocal.m4  autoscan.log    configure.in    main.c
autom4te.cache  configure   configure.scan

执行autoheader

$ autoheader
$ ls
aclocal.m4  autoscan.log    configure   configure.scan
autom4te.cache  config.h.in configure.in    main.c

创建Makefile.am文件

$ vi Makefile.am
如下：
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=main
main_SOURCES=main.c

执行automake --add-missing

$ automake --add-missing

$ ls

Makefile.in autoscan.log    configure   depcomp     missing
aclocal.m4  compile     configure.in    install-sh

执行 ./configure

$ ./configure

configure: creating ./config.status

执行make

$ make
/Applications/Xcode.app/Contents/Developer/usr/bin/make  all-am
gcc -DHAVE_CONFIG_H -I.     -g -O2 -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.c
mv -f .deps/main.Tpo .deps/main.Po
gcc  -g -O2   -o main main.o

测试生成的main可执行包

$ ./main
Hello, Auto Makefile!

$ make dist
