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。
我几次跟着这封信的步骤，但我不确定我哪里出错了。

我已经多次重做过了。有几次我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。我确保安装它，但是有些问题出了问题。
编辑：
我认为这不会很快得到解决，我没有时间对此进行真正的解决。我暂时转而使用RethinkDB。在几个月后，我会再次尝试。

构建过程（确保MongoDB服务器启动并运行后）
git clone -b 1.2.0-dev https://github.com/mongodb/mongo-c-driver
./autogen.sh
sudo make && sudo make install
git clone -b master https://github.com/mongodb/mongo-cxx-driver
cd mongo-cxx-driver/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo make && sudo make install
GCC and G++ version are 4.9.2

我现在还将我的cmake构建的标志添加到：
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C_COMPILER=/usr/bin/clang ..
clang version 3.4.2 (tags/RELEASE_34/dot2-final)
Target: x86_64-redhat-linux-gnu
Thread model: posix
我现在得到了更多/更好的错误。

将clang更新为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。

答案 0 :(得分：1)
我找到了这个问题。
#ifdef MONGOC_ENABLE_SSL
void mongoc_client_pool_set_ssl_opts (mongoc_client_pool_t *pool,
const mongoc_ssl_opt_t *opts);
#endif
MONGOC_ENABLE_SSL设置为0 。我将向MongoCXX驱动程序开发人员提出一个问题，以确保他们明确地将其放在维基页面上。
