我需要安装perl模块XML-LibXML。我已下载如下，并尝试安装。它说无法链接libxml2。然后我下载了libxml2并安装然后再次尝试但是它也没有成功。
所以我应该知道如何链接这个安装的libxml2。
我是否需要将libxml2安装目录（/ install / others / lib）添加到文件“/etc/ld.so.conf”中并通过运行以下命令更新动态加载程序缓存：ldconfig
bash-3.2$ wget http://search.cpan.org/CPAN/authors/id/S/SH/SHLOMIF/XML-LibXML-2.0019.tar.gz
bash-3.2$ tar zxvf XML-LibXML-2.0019.tar.gz
bash-3.2$ pwd

bash-3.2$ perl Makefile.PL LIBS='-L/install/others/lib' INC='-I/install/others/include'

Checking for ability to link against libxml2...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.

下面是DEBUG = 1添加的输出
bash-3.2$ pwd

它不是在寻找我的本地目录，它正在寻找
INC = -I/usr/local/include -I/usr/include
LIBS = -L/usr/local/lib -L/usr/lib -lxml2 -lz -lm
注意：我没有root访问权限，我的操作系统是linux RedHat。
提前致谢
你需要头文件。
它们作为libxml源代码分发的一部分提供，例如here。将libxml.../include目录解压缩到您的文件系统，并将目录包含在make调用的-I标志中。错误消息还表明在您的系统上找不到zlib和libm。它们可能位于非标准的/usr/lib...目录中，但会出现。在make调用的-L选项中包含找到的库。
如果您没有root访问权限，请尝试使用perlbrew：http://perlbrew.pl/
然后你可以轻松安装Alien :: XML :: LibXML（http://corion.net/perl-dev/Alien-XML-LibXML.html）
它只为您的本地Perl安装libxml。
在此之后，应成功安装XML-LibXML。
脚步：
1）使用perlbrew安装本地perl以保持系统perl清洁
2）使用perlbrew中的cpanm安装Alien :: XML :: LibXML
3）安装XML-LibXML
为您的Linux发行版安装Alien :: LibXML或下载LibXML二进制文件，
"export XMLPREFIX=$YOURLIBXMLPREFIX"
$$ YOURLIBXMLPREFIX / bin / xml2-config没问题。
然后通过cpan安装XML :: LibXML
