无法编译 mongo-cxx-driver
unable to compile mongo-cxx-driver
从 CXX Driver Quickstart guide 我完全无法在 Ubuntu 或 CentOS VM 上完成新驱动程序的编译。
我已经按照这封信的步骤进行了好几次，但我不确定哪里出了问题。

我已经重做了好几次了。好几次我都重新安装了整个操作系统。有问题的错误与 mongo-c-driver 的 1.2 开发版本有关。我确定安装了它，但是出了点问题。
编辑：
我认为这不会很快得到解决，而且我没有时间真正解决这个问题。我暂时改用了 RethinkDB。几个月后我会再试一次。

我现在遇到 more/better 错误。

将 clang 更新到 3.6，因为我认为这可能会解决一些问题。我重建了 libbson，libmongoc 并再次尝试。
