Linux工具之autoconf和automake

1 autoscan — 在 hello.c所在目录完成扫描

文件长生如下文件
┗ autoscan.log
┗ configure.scan
┗ mv configure.scan configure.ac
┗ edit configure,ac

修改 configure.ac的内容

#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
AC_PREREQ([2.69])
AC_INIT([FULL-PACKAGE-NAME], [VERSION], [BUG-REPORT-ADDRESS])
# add it
AM_INIT_AUTOMAKE
#change it 
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.
# add it 
AC_CONFIG_FILES([Makefile]) 
AC_OUTPUT

2 makefile.am — 创建添加如下信息

AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=helloworld
helloworld_SOURCES=hello.c

┗ binPROGRAMS 指定可执行输出文件
┗ helloworldSOURCES 制定输入的原文件

3 执行aclocal

├── aclocal.m4
├── autom4te.cache
│ ├── output.0
│ ├── requests
│ └── traces.0

4 执行autoheader | with sudo

├── aclocal.m4
├── autom4te.cache
│ ├── output.0
│ ├── output.1
│ ├── requests
│ ├── traces.0
│ └── traces.1
├── autoscan.log
├── config.h.in

:::warning autom4te: cannot open autom4te.cache/requests: Permission denied
autoheader: ‘/usr/bin/autom4te’ failed with exit status: 1
————————————————————————————————————————————————
sudo XXX :::

5 执行autoconf | with sudo

├── aclocal.m4
├── autom4te.cache
│ ├── output.0
│ ├── output.1
│ ├── requests
│ ├── traces.0
│ └── traces.1
├── autoscan.log
├── config.h.in
├── configure
├── configure.ac
├── main.c
└── Makefile.am

执行automake —add-missing | with sudo

├── aclocal.m4
├── autom4te.cache
│ ├── output.0
│ ├── output.1
│ ├── requests
│ ├── traces.0
│ └── traces.1
├── autoscan.log
├── compile -> /usr/share/automake-1.16/compile
├── config.h.in
├── configure
├── configure.ac
├── depcomp -> /usr/share/automake-1.16/depcomp
├── install-sh -> /usr/share/automake-1.16/install-sh
├── main.c
├── Makefile.am
├── Makefile.in
└── missing -> /usr/share/automake-1.16/missing**

经过以上操作我们就可以像一般安装程序一config —> make —> make install

安装

 ./configure
 make
 make install
 ┗  /usr/bin/install -c helloworld '/usr/local/bin'
这样直接可以直接执行，不用带上绝对路径

autogen.sh 登场

#!/bin/sh
echo 
echo ... helloworld autogen ...
echo 
MISSING=""
env aclocal --version >/dev/null 2>&1
if [ $? -eq 0 ];then
    ACLOCAL=aclocal
else
    MISSING="$MISSING aclocal"
fi
env autoconf --version > /dev/null 2>&1
if [ $? -eq 0 ];then

env autoheader --version > /dev/null 2>&1
if [ $? -eq 0 ]; then
    AUTOHEADER=autoheader

    MISSING="$MISSING autoconf"

env automake --version > /dev/null 2>&1
if [ $? -eq 0 ];then
    AUTOMAKE=automake

    MISSING="$MISSING automake"
fi
env libtoolize --version > /dev/null 2>&1
if [ $? -eq 0 ];then
    TOOL=libtoolize
else 
    env glibtoolize --version > /dev/null 2>&1
    if [$? -eq 0 ];then
        TOOL=glibtoolize
    else
        MISSING="$MISSING libtoolize/glibtoolize"
    fi
fi
env tar -cf /dev/null /dev/null > /dev/null 2>&1
if [ $? -ne 0 ];then
    MISSING="$MISSING tar"
fi
if [ "x$MISSING" != "x" ];then
    echo "ABORTING."
    echo 
    echo "The following build tools are missing:"
    echo 
    for pkg in $MISSING;do
        echo " *  $pkg"
    done
    echo 
    echo "please install them and try again."
    echo 
fi
