无法链接libxml2

我需要安装perl模块XML-LibXML。我已经下载并尝试安装。它说不能链接libxml2。然后我已经下载libxml2并安装，然后再次尝试，但也没有成功。
所以我应该知道如何链接这个已安装的libxml2。
我是否需要添加的libxml2安装目录（/安装/其它/ lib中）到文件“/etc/ld.so.conf中”和更新通过运行动态加载缓存：LDCONFIG无法链接libxml2

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 
/install/others/XML-LibXML-2.0019 

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

Checking for ability to link against xml2...no 
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.

以下是DEBUG = 1添加输出

它是不是找我的本地目录中，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：我没有root访问权限和我的歌剧系统是Linux RedHat。

在此先感谢

*如果你通过RPM包安装，请确保您还安装-devel RPM包，因为这是头（.h文件）是*。所以，有你安装了头文件？如果不是，请安装它们并重试Perl模块安装。如果是的话，他们在哪里？（另外，为什么你要手动安装模块，而不是像cpanm一样使用local :: lib工具？） – amon

您是否按照错误消息中的建议尝试了DEBUG = 1参数？ –

@amon：他没有root权限，所以股票rpm安装不起作用。 –

如果你没有root访问权限您尝试使用perlbrew：http://perlbrew.pl/

然后，你可以很容易地安装外国人:: XML ::的libxml（http://corion.net/perl-dev/Alien-XML-LibXML.html）

它安装libxml仅适用于本地Perl。

之后，应该成功安装XML-LibXML。

步骤：

1）安装与perlbrew本地Perl，以保持系统的perl干净

2）cpanm从安装外国人:: XML ::的libxml perlbrew

3）安装XML-的libxml

[Alien :: LibXML]（http://p3rl.org/Alien::LXXML）存在于CPAN上。 – daxim

不，请安装Alien：libxml不要让xml :: libxml安装，因为它还会在默认库路径中查找libxml。 – netawater

你需要头文件。

它们可作为libxml源分布的一部分，例如， here。将文件系统中的libxml.../include目录解压缩到某个位置，并将该目录包含在拨打电话的-I标志中。错误信息还表明zlib和libm无法在您的系统上找到。他们可能位于非标准/usr/lib...目录中，但会出现。请在拨打电话的-L选项中包含找到的库。

-1没有提到编译未安装的头文件的缺点。 – daxim

安装外国人::的libxml或下载二进制的libxml为您的Linux发行版，

"export XMLPREFIX=$YOURLIBXMLPREFIX" $$ YOURLIBXMLPREFIX /斌/ XML2-配置是OK。

然后通过CPAN安装XML ::的libxml
