我在 x86_64 架构的机器上运行，32 位编译的 Perl 5.8.4。当我尝试安装 XML::LibXML 时，我收到以下调试消息：

……

no
libxml2, zlib, and/or the Math library (-lm) have not been found.
Try setting LIBS and INC values on the command line
Or get libxml2 from 
  http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.

所以问题是，如何在 .cpan 属性（或 Makefile.PL）中描述我想在 64 位架构中以 32 位模式编译 XML::LibXML？

  1. 首先，检查您的系统上是否安装了 libxml2-devel 和 zlib-devel 软件包，如下所示：

    $ rpm -ql libxml2-devel

    $ rpm -ql zlib-devel

  2. 如果未安装其中任何一个，请按以下方式安装缺少的软件包：

    $ yum 安装 libxml2-devel

    $ yum install zlib-devel

  3. 使用 CPAN 重新安装 XML::LibXML pacak，如下所示：

    $cpan

    cpan> 安装 XML::LibXML

我希望这会有所帮助。祝你好运！
