autoconf/automake学习笔记


v0.1 2013.12.12 *** 明白流程


1. 写hello.c程序


2. autoscan 生成：autoscan.log  configure.scan  hello.c
   cat configure.scan:
#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.


AC_PREREQ([2.68])
AC_INIT([FULL-PACKAGE-NAME], [VERSION], [BUG-REPORT-ADDRESS])
AC_CONFIG_SRCDIR([hello.c])
        AC_CONFIG_HEADERS([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


   修改成：
   #                                               -*- Autoconf -*-
   # Process this file with autoconf to produce a configure script.


   AC_PREREQ([2.68])
   AC_INIT([autoconf_test, [0.1]) # change this line!
   AC_CONFIG_SRCDIR([hello.c])
   AC_CONFIG_HEADERS([config.h])
   AM_INIT_AUTOMAKE([autoconf], [0.1]) # add this line!


   # 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(Makefile) # change this line！


   把文件名改成: configure.in


3. aclocal 生成：
   aclocal.m4  autom4te.cache  configure.in  hello.c 
   (主要是生成aclocal.m4)


4. autoconf 生成：
   aclocal.m4  autom4te.cache  configure  configure.in  hello.c


5. autoheader 生成：
   aclocal.m4  autom4te.cache  config.h.in  configure  configure.in  hello.c


5. 创建Makefile.am:
   AUTOMAKE_OPTIONS=foreign
   bin_PROGRAMS=hello
   hello_SOURCES=hello.c


6. automake --add-missing 
   过程信息为：
   configure.in:8: installing `./install-sh'
   configure.in:8: installing `./missing'
   Makefile.am: installing `./depcomp'
   生成文件：
   aclocal.m4  autom4te.cache  config.h.in  configure  configure.in  depcomp  
   hello.c  install-sh  Makefile.am  Makefile.in  missing
   (makefile.in是这步生成的关键文件)


7. ./configure 生成最终的Makefile文件(该步骤中可能需要指定编译器：export CC=gcc)


8. make 生成最终的可执行的程序：hello, ./hello运行输出：test autoconf!


    /* hello.c */
#include<stdio.h>


int main()
{
printf("test autoconf!\n");


#ifdef CONFIG_H_TEST
printf("test autoconf: test config.h\n");
#endif


return 0;
}
