Would generate 2 file: autoscan.log configure.scan

3. Rename "configure.scan" to  "configure.in".

4.Modify the "configure.in" file.

Origin file is:

#                                               -*- Autoconf -*-
    # Process this file with autoconf to produce a configure script.
    
    AC_PREREQ([2.69])
    AC_INIT([FULL-PACKAGE-NAME], [VERSION], [BUG-REPORT-ADDRESS])
    AC_CONFIG_SRCDIR([main.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

Modified is:

#                                               -*- Autoconf -*-
    # Process this file with autoconf to produce a configure script.
    
    AC_PREREQ([2.69])
    AC_INIT(main, 1.0, xxxxxxx@qq.com) #修改
    AC_CONFIG_SRCDIR([main.c])
    AC_CONFIG_HEADERS([config.h])
    AM_INIT_AUTOMAKE(main,1.0) #新增
    
    # 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_CONFIG_FILES([Makefile]) #如果有，就不需要增加
    
    AC_OUTPUT

5.Input "aclocal", would generate 2 file: aclocal.m4 autom4te.cache

6.Input "autoconf", would generate 1 file: configure

![20181221125633891.png][]

7.Input "autoheader", would generate 1 file: configure.in

![20181221140408635.png][]

8.Create a file named "Makefile.am", contain is:

AUTOMAKE_OPTIONS=foreign
    bin_PROGRAMS=main
    main_SOURCES=main.c

7.Input "automake --add-missing", would generate server file.

8. Input  "./configure" to generate a Makefile, then you can use "make" command.
