说明 |
| autoscan |
扫描目录下文件
|
-
|
configure.scan |
|
|
aclocal
|
生成aclocal.m4
|
configure.scan->configure.ac
并编辑configure.ac增加部分内容
|
|
configure.ac 一般增加AM_INIT_AUTOMAKE([helloworld],1.0) 为可选
|
|
automake
|
根据Makefile.am生成Makefile.in
|
Makefile.am(手动创建)
|
Makefile.in
|
一般使用增加选项--add-missing
|
|
autoconf
|
生成configure
|
configure.ac
aclocal.m4
|
configure
|
|
引用张旧图:
图中configure.in更新为configure.ac
2.编译步骤
step1.手动创建源文件:
helloworld.c
#include <stdio.h>
int main(int argc, char** argv)
{
printf("Hello, Linux World!\n");
return 0;
}
step1.autoscan
自动生成 configure.scan
结果:
autoscan.log configure.scan helloworld.c
autoscan.log为空文件:
configure.scan
# -*- 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([helloworld.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
step2.手动编辑configure.scan
# -*- 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([helloworld.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
step3.执行aclocal
结果:
autom4te.cache autoscan.log configure.ac helloworld.c
step4.手动创建Makefile.am
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=
helloworld
helloworld
_SOURCES=
helloworld.c
step5.执行automake --add-missing
aclocal.m4 autom4te.cache autoscan.log configure.ac depcomp helloworld.c install-sh Makefile.am Makefile.in missing
step6.执行autoconf：
aclocal.m4 autom4te.cache autoscan.log configure configure.ac depcomp helloworld.c install-sh Makefile.am Makefile.in missing
step7.执行./configure
aclocal.m4 autoscan.log config.status configure.ac helloworld.c Makefile Makefile.in
autom4te.cache config.log configure depcomp install-sh Makefile.am missing
step8.执行make
aclocal.m4 autoscan.log config.status configure.ac helloworld helloworld.o Makefile Makefile.in
autom4te.cache config.log configure depcomp helloworld.c install-sh Makefile.am missing
