Question

我正在尝试安装taglib-ruby，但仍然遇到同样的错误：

xyz@ubuntu:~$ sudo gem install taglib-ruby
Building native extensions.  This could take a while...
ERROR:  Error installing taglib-ruby:
    ERROR: Failed to build gem native extension.

        /usr/bin/ruby1.9.1 extconf.rb
checking for main() in -lstdc++... no
You must have libstdc++ installed.
*** 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
    --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=/usr/bin/ruby1.9.1
    --with-tag-dir
    --without-tag-dir
    --with-tag-include
    --without-tag-include=${tag-dir}/include
    --with-tag-lib
    --without-tag-lib=${tag-dir}/lib
    --with-stdc++lib
    --without-stdc++lib


Gem files will remain installed in /var/lib/gems/1.9.1/gems/taglib-ruby-0.6.0 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/taglib-ruby-0.6.0/ext/taglib_base/gem_make.out

mkmf.log说明如下：

我按照自述文件中的说明进行操作，安装libtag1-dev并仔细检查我是否安装了libstdc ++（如果我错过了文件，我甚至会查看Ubuntu软件中心）。我发现的唯一类似问题是this one，但我已经尝试明确定义了opt-dir和opt-include这两种方法都无济于事。

我必须承认我对这个主题甚至Ubuntu都不是很熟悉，所以我可能会忽略或完全错过关于错误信息的明显错误。

Answer 1

Debian / Ubuntu：sudo apt-get install libtag1-dev

Fedora / RHEL：sudo yum install taglib-devel

Brew：brew install taglib

MacPorts：sudo port install taglib

在Ubuntu 12.04上安装taglib-ruby gem时缺少libstdc ++？
