Auto generate Makefile

All steps below referce: https://blog.csdn.net/qq_19004627/article/details/79061457

1. Install software.

Note: autoconf belong a part of "autotools" software.

sudo apt install autoconf

2.Generate

input "autoscan", as following:

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

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

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.
