如何为单个安装设置库并包含Makefile.PL的路径？

如何告诉CPAN Makefile.PL在一个特定的安装中给出一个特定的参数？

特别.我想安装XML::LibXML,并apt-get安装库/usr/lib/libxml2.so.2.6.32.Makefile.PL有问题并告诉我:

using fallback values for LIBS and INC
options:
  LIBS='-L/usr/local/lib -L/usr/lib -lxml2 -lm'
  INC='-I/usr/local/include -I/usr/include'
If this is wrong, Re-run as:
  $ /usr/bin/perl Makefile.PL LIBS='-L/path/to/lib' INC='-I/path/to/include'

looking for -lxml2... no
looking for -llibxml2... no
libxml2 not found
Try setting LIBS and INC values on the command line
Or get libxml2 from 
  http://xmlsoft.org/

我知道libxml2在哪里,但我不知道怎么告诉它Makefile.PL.

编辑:当我这样做时dpkg -L libxml2(它是一个debian),我明白了

/.

我不是该机器上的root用户,我无法进行符号链接/usr/lib或修复它.

在CPAN shell中,您可以设置所需的值:

$ cpan
cpan shell -- CPAN exploration and modules installation (v1.9205)
ReadLine support available (maybe install Bundle::CPAN or Bundle::CPANxxl?)

cpan[1]> o conf makepl_arg
    makepl_arg         []
Type 'o conf' to view all configuration items


cpan[2]> o conf makepl_arg "LIBS=-L/foo/bar INC=-I/foo/bar/include"
    makepl_arg         [LIBS=-L/foo/bar INC=-I/foo/bar/include]
Please use 'o conf commit' to make the config permanent!

cpan[3]> install Some::Module

使用cpan命令,您可以使用该-j开关加载自定义配置文件.您可以从-J交换机开始转储配置,然后更改所需的值并重新加载它:

 $ cpan -J > my_config.pm
 .... edit file ....
 $ cpan -j my_config.pm -i Some::Module

但是,我怀疑rafl的怀疑是正确的.
