autogen.sh

**autogen.sh**是个shell脚本，用来简化生成configure的。

下面是常用的autogen.sh内容，可以看出就是检查环境并依次调用 aclocal、autoconf、autoheader、libtoolize、automake 这些命令来生成configure，把这些命令封装、不需要一条条执行，只需要执行**autogen.sh**脚本即可**。**

[root@localhost autogen_test]# vim autogen.sh 
    [root@localhost autogen_test]# cat autogen.sh 
    #!/bin/sh
    echo
    echo ... auto_test autogen ...
    echo
     
    ## Check all dependencies are present
    MISSING=""
     
    # Check for aclocal
    env aclocal --version > /dev/null 2>&1
    if [ $? -eq 0 ]; then
      ACLOCAL=aclocal
    else
      MISSING="$MISSING aclocal"
    fi
     
    # Check for autoconf
    env autoconf --version > /dev/null 2>&1
    if [ $? -eq 0 ]; then
      AUTOCONF=autoconf
    else
      MISSING="$MISSING autoconf"
    fi
     
    # Check for autoheader
    env autoheader --version > /dev/null 2>&1
    if [ $? -eq 0 ]; then
      AUTOHEADER=autoheader
    else
      MISSING="$MISSING autoheader"
    fi
     
    # Check for automake
    env automake --version > /dev/null 2>&1
    if [ $? -eq 0 ]; then
      AUTOMAKE=automake
    else
      MISSING="$MISSING automake"
    fi
     
    # Check for libtoolize or glibtoolize
    env libtoolize --version > /dev/null 2>&1
    if [ $? -eq 0 ]; then
      # libtoolize was found, so use it
      TOOL=libtoolize
    else
      # libtoolize wasn't found, so check for glibtoolize
      env glibtoolize --version > /dev/null 2>&1
      if [ $? -eq 0 ]; then
        TOOL=glibtoolize
      else
        MISSING="$MISSING libtoolize/glibtoolize"
      fi
    fi
     
    # Check for tar
    env tar -cf /dev/null /dev/null > /dev/null 2>&1
    if [ $? -ne 0 ]; then
      MISSING="$MISSING tar"
    fi
     
    ## If dependencies are missing, warn the user and abort
    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
      exit 1
    fi
     
    ## Do the autogeneration
    echo Running ${ACLOCAL}...
    $ACLOCAL 
    echo Running ${AUTOHEADER}...
    $AUTOHEADER
    echo Running ${TOOL}...
    $TOOL --automake --copy --force
    echo Running ${AUTOCONF}...
    $AUTOCONF
    echo Running ${AUTOMAKE}...
    $AUTOMAKE --add-missing --force-missing --copy --foreign
     
    # Run autogen in the argp-standalone sub-directory
    #echo "Running autogen.sh in argp-standalone ..."
    #( cd contrib/argp-standalone;./autogen.sh )
     
    # Instruct user on next steps
    echo
    echo "Please proceed with configuring, compiling, and installing."

还有一种使用autoreconf的

GNU autoconf工具。通过在指定目录和子目录中运行autoconf，autoheader，aclocal，automake和libtoolize更新配置脚本。很少手动调用此命令。通常可以从其他autoconf工具中自动调用它

#!/bin/sh
    # Run this to generate configure, Makefile.in's, etc
    
    (autoreconf --version) < /dev/null > /dev/null 2>&1 || {
      (autoconf --version) < /dev/null > /dev/null 2>&1 || {
        echo
        echo "**Error**: You must have the GNU Build System (autoconf, automake, "
        echo "libtool, etc) to update the build system.  Download the "
        echo "appropriate packages for your distribution, or get the source "
        echo "tar balls from ftp://ftp.gnu.org/pub/gnu/."
        exit 1
      }
      echo
      echo "**Error**: Your version of autoconf is too old (you need at least 2.57)"
      echo "to update the  build system.  Download the appropriate "
      echo "updated package for your distribution, or get the source tar ball "
      echo "from ftp://ftp.gnu.org/pub/gnu/."
      exit 1
    }
    
    echo Running autoreconf --verbose --install --force
    autoreconf --verbose --install --force

autogen.sh
