Mongodb C++ 编译问题

Question

我正在尝试为 C++ 编译 mongodb 驱动程序并遵循 url 中给出的说明：Mongocxx

我遇到以下错误：

-- The CXX compiler identification is GNU 4.8.5
-- Check for working CXX compiler: /bin/c++
-- Check for working CXX compiler: /bin/c++ -- works

我检查过 libbson 已经安装在 /usr/local/bin 中。无法找出根本原因。请协助。

如果您正在构建版本 3.1.X 或 3.0.x，您必须指定 libmongoc（mongodb c 驱动程序）安装的 libbson。

"Users building mongocxx versions 3.1.x and 3.0.x should specify the libmongoc installation directory by using the -DLIBMONGOC_DIR and -DLIBBSON_DIR options to cmake. See the following example, which assumes that both libmongoc and libbson are installed into /your/cdriver/prefix:"

如果您在 linux 系统上构建，请尝试这样的操作：

cmake -DCMAKE_BUILD_TYPE=发布 -DCMAKE_INSTALL_PREFIX=/usr/local .. -DBSONCXX_POLY_USE_MNMLSTC=1 -DLIBMONGOC_DIR=/usr -DLIBBSON_DIR=/usr/lib64
