生成Makefile的步骤如下：
vim Makefile.am
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=add
add_SOURCES=main.c add.c
done@done-desktop:~/programs/automaketest/flatc$ autoscan ./
done@done-desktop:~/programs/automaketest/flatc$ ls
add.c  add.h  autoscan.log  configure.scan  main.c  Makefile.am
done@done-desktop:~/programs/automaketest/flatc$ cp configure.scan configure.ac
修改configure.ac:
#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
