ruby-on-rails - 无法在Fedora16中gem安装nokogiri

我在Fedora16中运行Ruby1.9.3p194和Rails3.2.9。
当我gem install nokogiri时，它失败，并显示错误消息：

    ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

        /home/chelseaw/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

libiconv is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

我在网上搜索了很久，但只找到了一些MacOS的解决方案我不知道该怎么办，请帮忙。

最佳答案

终于成功了，下面是步骤：
下载libiconv
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz
提取文件tar -xvzf libiconv-1.11.tar.gz
输入目录cd libiconv-1.11
配置libiconv库./configure --prefix=/usr/local/libiconv
编译libiconvmake CFLAGS="-O2 -fno-tree-dce -fno-optimize-sibling-calls"（我必须添加cflags才能使编译生效。）
安装libiconvsudo make install
安装nokogiri
CFLAGS="-O2 -fno-tree-dce -fno-optimize-sibling-calls" gem install nokogiri -- --with-iconv-dir=/usr/local/libiconv --with-iconv-lib=/usr/local/libiconv/lib --with-iconv-include=/usr/local/libiconv/include
瞧，它显示了成功的信息！
