如何为单个安装设置库并包含Makefile.PL的路径？ [英] How can I set library and include paths for Makefile.PL for a single installation?

问题描述

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

How can I tell CPAN to give Makefile.PL one specific argument in one specific installation?

具体来说。我想安装 XML :: LibXML ，并且 apt-get 将库安装到 / usr / lib / libxml2.so.2.6.32 。 Makefile.PL 对此有问题，并告诉我：

Specifically. I want to install XML::LibXML, and apt-get installed the library to /usr/lib/libxml2.so.2.6.32. Makefile.PL has problems with that and tells me:

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/

$ b中获取libxml2
$ b

我知道libxml2在哪里，但我不知道如何将其告诉。

I know where the libxml2 is, but I don't know how to tell it to the Makefile.PL.

编辑：当我执行 dpkg -L libxml2 （是debian）时，我看到

edit: When I do dpkg -L libxml2 (it's a debian), I see

/.
/usr
/usr/lib
/usr/lib/libxml2.so.2.6.32
/usr/share
/usr/share/doc
/usr/share/doc/libxml2
/usr/share/doc/libxml2/AUTHORS
/usr/share/doc/libxml2/changelog.Debian.gz
/usr/share/doc/libxml2/copyright
/usr/share/doc/libxml2/README
/usr/share/doc/libxml2/README.Debian
/usr/share/doc/libxml2/NEWS.gz
/usr/share/doc/libxml2/changelog.gz
/usr/share/doc/libxml2/TODO.gz
/usr/lib/libxml2.so.2

我不是该计算机的root用户，因此无法在 /中建立符号链接usr / lib 或对其进行修复。

I am not a root on that machine and I can't make symlink in /usr/lib or repair it.

推荐答案

Makefile.PL正在寻找 libxml2.so 。这通常是指向实际libxml2共享库的符号链接，例如 libxml2.so.2.6.32 。如果由于某种原因该符号链接由于删除而没有出现，则您的供应商未将其带有libxml2头文件包（例如Debian / Ubuntu /上的 libxml2-dev 附带在内）

The Makefile.PL is looking for libxml2.so. That's usually a symlink to your actual libxml2 shared object, like libxml2.so.2.6.32. If for some reason this symlink isn't around because you deleted it, your vendor didn't ship it with its libxml2 header package (e.g. libxml2-dev on Debian/Ubuntu/etc), you will need to create it yourself.

您无需在此处将任何特定的参数传递给Makefile.PL。它已经在正确的位置寻找。它所寻找的东西根本就不存在。

You don't need to pass any specific argument to Makefile.PL here. It's already looking in the right places. The things it's looking for simply aren't there.
