webrat - 无法构建 gem —— native 扩展构建失败 —— 你能明白为什么吗？

Question

我不知道这里出了什么问题——有什么想法吗？

我在 Ubuntu 8.04 LTS 上运行，并按照以下说明安装了 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

安装很顺利

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

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

------------- 看起来该函数是存在的——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

------------------------ 但是编译还是失败-------------------- ----------------------------------

由于某种原因无法创建 Makefile，可能缺少
必要的库和/或 header 。检查 mkmf.log 文件了解更多信息
细节。您可能需要配置选项。
