0）准备工作：

[root@yznvm1 yzn]# whereis aclocal autoscan
aclocal: /usr/bin/aclocal /usr/share/aclocal

1） 编辑hellworld.c文件
#include<stdio.h>
int main(int argc, char** argv)
{
printf("Hello world, Lvping.com !n");
return 0;
}
2)autoscan-〉configure.scan
[root@yznvm1 helloworld]# autoscan
autom4te: configure.ac: no such file or directory
autoscan: /usr/bin/autom4te failed with exit status: 1
[root@yznvm1 helloworld]# ls
autoscan.log configure.scan helloworld.c
[root@yznvm1 helloworld]# cat configure.scan
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
AC_PREREQ(2.59)
AC_INIT(FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS)
AC_CONFIG_SRCDIR([helloworld.c])
AC_CONFIG_HEADER([config.h])
# Checks for programs.
AC_PROG_CC
# Checks for libraries.
# Checks for header files.
# Checks for typedefs, structures, and compiler characteristics.
# Checks for library functions.
AC_OUTPUT
3)编辑configure.ac
[root@yznvm1 helloworld]# cp configure.scan configure.ac
[root@yznvm1 helloworld]# vi configure.ac
[root@yznvm1 helloworld]# cat configure.ac
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
AC_PREREQ(2.59)
AC_INIT(helloworld, 1.0, yanzhenan@126.com)

# Checks for library functions.
AC_OUTPUT(Makefile)
4)aclocal-〉aclocal.m4
[root@yznvm1 helloworld]# aclocal
[root@yznvm1 helloworld]# ls
aclocal.m4 autom4te.cache autoscan.log configure.ac configure.scan helloworld.c
5）autoconf -〉configure
[root@yznvm1 helloworld]# autoconf
[root@yznvm1 helloworld]# ls
aclocal.m4 autom4te.cache autoscan.log configure configure.ac configure.scan helloworld.c
6）autoheader ->config.h.in
[root@yznvm1 helloworld]# find / -name acconfig.h
/usr/src/kernels/2.6.18-238.el5-x86_64/include/acpi/acconfig.h
[root@yznvm1 helloworld]# autoheader
[root@yznvm1 helloworld]# ls
aclocal.m4 autom4te.cache autoscan.log config.h.in configure configure.ac configure.scan helloworld.c
[root@yznvm1 helloworld]# more config.h.in
/* config.h.in. Generated from configure.ac by autoheader. */
/* Name of package */
#undef PACKAGE
/* Define to the address where bug reports for this package should be sent. */
#undef PACKAGE_BUGREPORT
/* Define to the full name of this package. */
#undef PACKAGE_NAME
/* Define to the full name and version of this package. */
#undef PACKAGE_STRING
/* Define to the one symbol short name of this package. */
#undef PACKAGE_TARNAME
/* Define to the version of this package. */
#undef PACKAGE_VERSION
/* Version number of package */
#undef VERSION
7)编辑Makefile.am文件
[root@yznvm1 helloworld]# cat Makefile.am
AUTOMAKE_OPTIONS = foreign
bin_PROGRAMS = helloworld
helloworld_SOURCES = helloworld.c
8）automake->makefile.in
[root@yznvm1 helloworld]# automake
configure.ac: required file `./install-sh' not found
configure.ac: required file `./missing' not found
Makefile.am: required file `./depcomp' not found
这样会报错
[root@yznvm1 helloworld]# automake --add-missing
configure.ac: installing `./install-sh'
configure.ac: installing `./missing'
Makefile.am: installing `./depcomp'
[root@yznvm1 helloworld]# ls
aclocal.m4 autom4te.cache autoscan.log config.h.in configure configure.ac configure.scan depcomp helloworld.c install-sh Makefile.am Makefile.in missing
[root@yznvm1 helloworld]# ls
aclocal.m4 autoscan.log config.h.in config.status configure.ac depcomp install-sh Makefile.am missing
autom4te.cache config.h config.log configure configure.scan helloworld.c Makefile Makefile.in stamp-h1
9）编译运行即可

调试：
如果需要用gdb 调试
./configure CPPFLAGS='-ggdb3'
这样配置后
make
gdb helloworld
然后输入 (gdb)break main,(gdb)run,(gdb)step等就可调试了。

有比较全面的介绍，不过其中流程图有少许错误，需要注意。
总流程
helloworld.c(autoscan)-〉configure.scan (cp,vi)->configure.ac(aclocal)->aclocal.m4 (autoconf) -〉configure
(autoheader) ->config.h.in
Makefile.am(automake)->makefile.in(automake)->Makefile
Configure
