I’ve search on internet and get quick steps for whole process to generate Makefile by Autotools.

autoscan . // scan the folder

cp configure.scan configure.ac // copy the configure.scan to configure.ac

vi configure.ac // edit the configure.ac

                              // add AM_INIT_AUTOMAKE(hello,1.0) in configure.ac  


                              // this is required marco for automake  

aclocal // execute aclocal to generate aclocal.m4

autoconf // execute autoconf to generate configure

autoheader

automake –add-missing // run automake

touch NEWS; touch README; touch AUTHORS; touch ChangeLog // create related documents

automake –add-missing // run automake again

./configure // execute the configure to generate Makefile

make // execute make

According to the steps, I get more hint to modify the related files for my target.
