我正在尝试安装 id3lib-ruby,但出现此错误:
Building native extensions. This could take a while...
ERROR: Error installing id3lib-ruby:
ERROR: Failed to build gem native extension.
/home/rfischer/.rvm/rubies/ree-1.8.7-2012.02/bin/ruby extconf.rb

You must have libstdc++ installed.
*** extconf.rb failed ***
我已经安装了各种 libstdc++:
$ apt-cache search libstdc | grep dev
lib32gmp-dev - Multiprecision arithmetic library developers tools (32bit)
libgmp-dev - Multiprecision arithmetic library developers tools
libstdc++6-4.4-dev - GNU Standard C++ Library v3 (development files)
libstdc++6-4.6-dev - GNU Standard C++ Library v3 (development files)
libstdc++6-4.7-dev - GNU Standard C++ Library v3 (development files)
libstdc++6-4.5-dev - GNU Standard C++ Library v3 (development files)

这是 mkmf.log:
