無法編譯mongo-cxx-driver

Question

從CXX驅動程序快速入門指南中，我完全無法在Ubuntu或CentOS VM上完成新驅動程序的編譯。

我已經按照信中的步驟進行了幾次，但是我不確定哪里出了問題。

In file included from /home/sam/downloads/mongo-cxx-driver/src/mongocxx/private/bulk_write.hpp:20:0,
                 from /home/sam/downloads/mongo-cxx-driver/src/mongocxx/bulk_write.cpp:19:
/home/sam/downloads/mongo-cxx-driver/src/mongocxx/private/libmongoc.hpp:31:63: error: ‘mongoc_client_pool_set_ssl_opts’ was not declared in this scope
 #define MONGOCXX_LIBMONGOC_SYMBOL(name) constexpr auto name = mongoc_##name;
                                                               ^
/home/sam/downloads/mongo-cxx-driver/src/mongocxx/private/libmongoc_symbols.hpp:42:1: note: in expansion of macro ‘MONGOCXX_LIBMONGOC_SYMBOL’
 MONGOCXX_LIBMONGOC_SYMBOL(client_pool_set_ssl_opts)

我已經重做了幾次。 幾次我都重新安裝了整個操作系統。 有問題的錯誤與mongo-c-driver的1.2開發版本有關。 我已經確定要安裝它，但是出錯了。

編輯：

我認為這不會很快得到解決，而且我沒有時間真正解決此問題。 我暫時已移至RethinkDB。 再過幾個月，我會再次嘗試一下。

EDIT2：

生成過程（確保MongoDB服務器已啟動並正在運行）

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

現在，我還將我的cmake構建的標志添加到：

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

我現在遇到了更多/更好的錯誤。

我認為將clang更新為3.6，可能會解決一些問題。 我重建了libbson，libmongoc，然后再次嘗試。

Answer 1

我發現了問題。

#ifdef MONGOC_ENABLE_SSL
void                  mongoc_client_pool_set_ssl_opts (mongoc_client_pool_t   *pool,
                                                       const mongoc_ssl_opt_t *opts);
#endif

由於我沒有安裝OpenSSL-devel軟件包，因此MONGOC_ENABLE_SSL設置為0 。 我將向MongoCXX驅動程序開發人員提出一個問題，以確保他們將其清楚地放在Wiki頁面上。
