关于在雪豹上安装链接解析器宝石的问题

Question

我无法使链接解析器宝石在我的雪豹上工作。

当我尝试做“sudo的创业板安装linkparser”，我得到：

Building native extensions. This could take a while... 
ERROR: Error installing linkparser: 
    ERROR: Failed to build gem native extension. 

     /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb 
checking for pkg-config... no 
*** 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. 

Provided configuration options: 
    --with-opt-dir 
    --without-opt-dir 
    --with-opt-include

    --without-link-grammar 
    --with-pkg-config 
    --without-pkg-config

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/linkparser-1.1.0 for inspection. 
Results logged to /Library/Ruby/Gems/1.8/gems/linkparser-1.1.0/ext/gem_make.out 

当我编译链接语法4.3.5从源代码（很顺利），然后尝试做“耙” ：

如何解决这个问题？编译链接语法时是否需要指定特殊的编译选项？

Answer 1

看起来您需要安装pkg-config。

我建议先安装XCode（如果还没有的话），然后Homebrew（OS X的包管理器），然后在终端中运行brew install pkg-config来安装它。

如果您已安装MacPorts或Fink，我相信您也可以在其存储库中找到相应的软件包。
