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.

--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib

Gem files will remain installed in /home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46 for inspection.
Results logged to /home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46/ext/gem_make.out
Who can tell me where the error is?
谁能告诉我错误在哪里？

The error is in the mkmf.log file. That file should be located at /home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46/ext/linecache/mkmf.log.
错误在 mkmf.log 文件中。该文件应位于/home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46/ext/linecache/mkmf.log.
If not, you can use
如果没有，您可以使用
sudo find / -name mkmf.log
to find it.
找到它。

I am using Mac El Capitan. In my case it was caused by the missing developer tool. I solved it by installing the developer tool via xcode-select --install. After that bundle install worked fine again.
我正在使用 Mac El Capitan。在我的情况下，它是由缺少开发人员工具引起的。我通过安装开发人员工具解决了这个问题xcode-select --install。在捆绑安装之后再次正常工作。

You're most likely missing some file headers (e.g. zlib or libiconv), so try installing them.
您很可能缺少某些文件头（例如 zlib 或 libiconv），因此请尝试安装它们。
Linux: sudo apt-get install libz-dev libiconv-hook1 libiconv-hook-dev
Linux： sudo apt-get install libz-dev libiconv-hook1 libiconv-hook-dev
OS X: brew install libiconv && xcode-select --install
操作系统： brew install libiconv && xcode-select --install
Otherwise check your mkmf.logfile for more specific details.
否则，请检查您的mkmf.log文件以获取更具体的详细信息。

It seems to be a issue with permission of gcc.. however, if you're using OS X, you may encounter this issue if you've updated your XCode but haven't agree to their terms & conditions yet.. try typing gccin your terminal would show you what if you've agreed.
这似乎是与海湾合作委员会的权限的问题。但是，如果你使用的OS X，你可能会遇到这个问题，如果你已经更新您的Xcode，但还没有同意他们的条款和条件尚未..尝试打字gcc中如果你同意，你的终端会告诉你什么。

My mkmf.log showed that gcc (4.8.2 I think) didn't like a specific argument that was being used by atomic on
我的 mkmf.log 显示 gcc（我认为是 4.8.2）不喜欢 atomic on
$ gem install atomic
So I had a very similar situation. The answer for me was to upgrade gcc/gcc-libs and lib tool.
所以我遇到了非常相似的情况。我的答案是升级 gcc/gcc-libs 和 lib 工具。
I use Arch linux, and only Arch linux. The proper way to do this is to run
我使用 Arch linux，并且只使用 Arch linux。正确的方法是运行
$ sudo pacman -Syu
which upgrades all system packages.
升级所有系统包。
I installed Rails and hadn't run a system update since, which is where the issue came from. In most other *nix distros, you would update to the latest version of these packages by name, i.e. with apt, it would be something along the lines of
我安装了 Rails 并且此后没有运行系统更新，这就是问题的来源。在大多数其他 *nix 发行版中，您将按名称更新到这些软件包的最新版本，即使用 apt，这将类似于
$ sudo apt-get update
followed by
其次是
$ sudo apt-get upgrade {package-name}

For what it's worth, using Ruby 2.0.0 I was having this problem on OSX 10.10.

I ended up running brew update, which resolved some conflicts, then installed the gem and it was fine.
我最终运行了brew update，它解决了一些冲突，然后安装了 gem，它很好。
