perl升级安装 博客分类： 开源软件Bash ShellLinux命令 perlupdateinstall安装升级

Linux服务器，perl版本为5.8.*，

最近在学习perl，所以需要把perl升级到最新版本，

你可以在这里下载得到最新版本（截止到现在的最新版是perl-5.14.2）：

http://www.cpan.org/src/5.0/perl-5.14.2.tar.gz

 

解压完成之后，进入目录，

 

$ ./Configure -h

 查看的编译的帮助信息：

 

./Configure -h
Usage: Configure [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
                 [-U symbol] [-U symbol=] [-A command:symbol...]
  -d : use defaults for all answers.
  -e : go on without questioning past the production of config.sh.
  -f : specify an alternate default configuration file.
  -h : print this help message and exit (with an error status).
  -r : reuse C symbols value if possible (skips costly nm extraction).
  -s : silent mode, only echoes questions and essential information.
  -D : define symbol to have some value:
         -D symbol         symbol gets the value 'define'
         -D symbol=value   symbol gets the value 'value'
       common used examples (see INSTALL for more info):
         -Duse64bitint            use 64bit integers
         -Duse64bitall            use 64bit integers and pointers
         -Dusethreads             use thread support
         -Dinc_version_list=none  do not include older perl trees in @INC
         -DEBUGGING=none          DEBUGGING options
         -Dcc=gcc                 choose your compiler
         -Dprefix=/opt/perl5      choose your destination
  -E : stop at the end of questions, after having produced config.sh.
  -K : do not use unless you know what you are doing.
  -O : let -D and -U override definitions from loaded configuration file.
  -S : perform variable substitutions on all .SH files (can mix with -f)
  -U : undefine symbol:
         -U symbol    symbol gets the value 'undef'
         -U symbol=   symbol gets completely empty
       e.g.:  -Uversiononly
  -A : manipulate symbol after the platform specific hints have been applied:
         -A append:symbol=value   append value to symbol
         -A symbol=value          like append:, but with a separating space
         -A define:symbol=value   define symbol to have value
         -A clear:symbol          define symbol to be ''
         -A define:symbol         define symbol to be 'define'
         -A eval:symbol=value     define symbol to be eval of value
         -A prepend:symbol=value  prepend value to symbol
         -A undef:symbol          define symbol to be 'undef'
         -A undef:symbol=         define symbol to be ''
       e.g.:  -A prepend:libswanted='cl pthread '
              -A ccflags=-DSOME_MACRO
  -V : print version number and exit (with a zero status).

 

这里使用 -de --Dusethreads 参数，所以用这条命令编译（详细参数意义请查看上面的help信息）：

 

$ ./Configure -de --Dusethreads

 

 

等待一会儿，没有问题之后执行：

 

$ make

$ make test

$ make install

 

注：这几个步骤比较久，要耐心等待~哈

 

完成之后用 $ perl -v 来查看更新后的信息：

 

perl -v

 如果还是之前的版本，可能你需要删除掉原来的软连接，建立新的软连接到/usr/bin目录下。

比如说：

ln -s /usr/local/bin/perl /usr/bin/perl
