在雪豹上安装链接解析器 gem 的问题

Question

我无法让链接解析器 gem 在我的雪豹上工作。

当我尝试执行“sudo gem install linkparser”时，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-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
    --with-link-grammar
    --without-link-grammar
    --with-pkg-config
    --without-pkg-config
extconf.rb:18: Couldn't find your pkg-config binary (RuntimeError)


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

当我从源代码编译链接语法 4.3.5（它运行良好）然后尝试执行“rake”时：

Task library 'rake/manual.rb' failed to load: NameError: uninitialized constant MANUALDIR. Some tasks may not be available.
No DarkFish: LoadError: no such file to load -- darkfish-rdoc

如何解决这个问题？编译链接语法时是否需要指定任何特殊的编译选项？

看来你需要安装pkg-config。

我建议先安装XCode（如果您还没有安装），然后安装Homebrew（OS X 的包管理器），然后在终端中运行brew install pkg-config。

如果您已经安装了 MacPorts 或 Fink，我相信您也可以在它们的存储库中找到合适的包。
