无法构建gem - 原生扩展构建失败 - 你能看出原因吗？

Question

我无法弄清楚这里出了什么问题 - 任何想法？

我正在运行Ubuntu 8.04 LTS,并从这些说明安装了libxml2和libxslt:

http://www.techsww.com/tutorials/libraries/libxml/installation/installing_libxml_on_ubuntu_linux.php

http://www.techsww.com/tutorials/libraries/libxslt/installation/installing_libxslt_on_ubuntu_linux.php

但是,我安装了最新版本:

libxslt-1.1.24
libxml2-2.7.3

安装平安无事

--------------------我设置LD_LIBRARY_PATH---------------------------- ------

echo $LD_LIBRARY_PATH
/usr/local/libxslt/lib:

-------------似乎函数存在 - 至少基于字符串的输出------------
/ usr/local/libxslt/lib $字符串*| grep ParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc

-----------------------但编译仍然失败---------------------- ------------------

在Ubuntu中你需要按照以下步骤操作:sudo apt-get install libxml2-dev sudo apt-get install libxslt-dev
