無法鏈接libxml2

我需要安裝perl模塊XML-LibXML。我已經下載並嘗試安裝。它說不能鏈接libxml2。然後我已經下載libxml2並安裝，然後再次嘗試，但也沒有成功。
所以我應該知道如何鏈接這個已安裝的libxml2。
我是否需要添加的libxml2安裝目錄（/安裝/其它/ lib中）到文件「/etc/ld.so.conf中」和更新通過運行動態加載緩存：LDCONFIG無法鏈接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

Try setting LIBS and INC values on the command line 
Or get libxml2 from

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.

它是不是找我的本地目錄中，它正在尋找

INC = -I/usr/local/include -I/usr/include 
LIBS = -L/usr/local/lib -L/usr/lib -lxml2 -lz -lm

注：我沒有root訪問權限和我的歌劇系統是Linux RedHat。

在此先感謝

*如果你通過RPM包安裝，請確保您還安裝-devel RPM包，因爲這是頭（.h文件）是*。所以，有你安裝了頭文件？如果不是，請安裝它們並重試Perl模塊安裝。如果是的話，他們在哪裏？（另外，爲什麼你要手動安裝模塊，而不是像cpanm一樣使用local :: lib工具？） – amon

您是否按照錯誤消息中的建議嘗試了DEBUG = 1參數？ –

@amon：他沒有root權限，所以股票rpm安裝不起作用。 –

如果你沒有root訪問權限您嘗試使用perlbrew：http://perlbrew.pl/

然後，你可以很容易地安裝外國人:: XML ::的libxml（http://corion.net/perl-dev/Alien-XML-LibXML.html）

它安裝libxml僅適用於本地Perl。

之後，應該成功安裝XML-LibXML。

步驟：

1）安裝與perlbrew本地Perl，以保持系統的perl乾淨

2）cpanm從安裝外國人:: XML ::的libxml perlbrew

3）安裝XML-的libxml

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

不，請安裝Alien：libxml不要讓xml :: libxml安裝，因爲它還會在默認庫路徑中查找libxml。 – netawater

你需要頭文件。

它們可作爲libxml源分佈的一部分，例如， here。將文件系統中的libxml.../include目錄解壓縮到某個位置，並將該目錄包含在撥打電話的-I標誌中。錯誤信息還表明zlib和libm無法在您的系統上找到。他們可能位於非標準/usr/lib...目錄中，但會出現。請在撥打電話的-L選項中包含找到的庫。

-1沒有提到編譯未安裝的頭文件的缺點。 – daxim

安裝外國人::的libxml或下載二進制的libxml爲您的Linux發行版，

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

然後通過CPAN安裝XML ::的libxml
