C++ 无法编译mongo cxx驱动程序

从一开始，我就完全无法在Ubuntu或CentOS虚拟机上完成新驱动程序的编译

我已经按照这些步骤写了好几次了，但我不确定哪里出了错

我已经重复了好几次了。我已经多次重新安装了整个操作系统。所讨论的错误与mongo-c-driver的1.2开发版本有关。我已经确定要安装了，但是出了点问题

编辑：

我认为这不会很快得到解决，我没有时间来真正解决这个问题。我暂时搬到了DB。几个月后，我会再次尝试

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)

我现在犯了更多/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并重试

我发现了这个问题

#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被设置为0，因为我没有安装OpenSSL-devel软件包。我将向MongoCXX驱动程序开发人员提出一个问题，以确保他们在wiki页面上清楚地指出这一点。

我不确定到底出了什么问题。我刚刚进行了测试，并根据当前的C驱动程序1.2.0-dev HEAD从源代码重新构建了C++11驱动程序，一切正常。如何构建和安装C驱动程序（autogen、configure和make命令）？配置C++11驱动程序构建的CMake行是什么？刚刚添加到我的构建过程中。它完全基于上面的文件。当我运行C++11驱动程序CMake时，我在输出中得到如下行：find libbson-1.0，version 1.2.0-dev和find libmongoc-1.0，version 1.2.0-dev。您在CMake输出中看到这些行了吗？您的系统上是否有其他mongodb C驱动程序副本？您执行安装的C驱动程序是在哪里生成的？是的，否，除非他们使用mongodb安装，并且它似乎安装到usr/local/include/mongoc/usr/local/lib/您能用CMake输出更新您的问题吗？“locate mongoc.h”在您的系统上返回什么？在调用CMake之前，能否尝试在环境中设置PKG_CONFIG_PATH=/usr/local？
