无法构建gem-本机扩展构建失败-您知道为什么吗? [英] Can't build gem -- native extension build fails -- can you see why?

问题描述

我不知道这里出了什么问题-任何想法吗?

I can't figure out what is going wrong here -- any ideas??

我正在Ubuntu 8.04 LTS上运行，并按照以下说明安装了libxml2和libxslt:

I'm running on a Ubuntu 8.04 LTS, and have installed libxml2 and libxslt from these instructions:

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:

However, I installed the latest versions:

libxslt-1.1.24
libxml2-2.7.3

libxslt-1.1.24
libxml2-2.7.3

安装很顺利

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

-------------------- I set LD_LIBRARY_PATH ----------------------------------

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

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

-------------似乎该函数存在-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

------------- seems like the function is present -- at least based on the output of strings ------------
/usr/local/libxslt/lib$ strings * | grep ParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc
xsltParseStylesheetDoc

-----------------------但是编译仍然失败------------------- ---------------------

----------------------- But the compile still fails ----------------------------------------

推荐答案

尝试删除libxslt *并重新安装.这为我解决了这个问题.

Try removing the libxslt* and install them again. That fixed the issue for me.
