Question

我在具有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，我得到以下调试消息：

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？

首先，检查系统上是否安装了libxml2-devel和zlib-devel软件包，如下所示：

$ rpm -ql libxml2-devel

$ rpm -ql zlib-devel
如果未安装任何软件包，请安装缺少的软件包，如下所示：

$ yum install libxml2-devel

$ yum install zlib-devel
使用CPAN重新安装XML :: LibXML pacak，如下所示：

$ cpan

CPAN＆GT;安装XML :: LibXML

我希望这会有所帮助。祝你好运！
