先决条件：

- CMake 版本大于3.2
- gcc 4.8, 5.4
- ubuntu 16.04
- git

mongoc driver 1.14.0 安装

  1 wget “https://github.com/mongodb/mongo-c-driver/releases/download/1.14.0/mongo-c-driver-1.14.0.tar.gz”
  2 tar xzf mongo-c-driver-1.14.0.tar.gz
  3 cd mongo-c-driver-1.14.0.tar.gz
  4 mkdir cmake-build
  5 cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..
  6 make
  7 sudo make install

mongocxx 3.4.0

  1 wget "https://github.com/mongodb/mongo-cxx-driver/archive/r3.4.0.tar.gz"
  2 tar -xzf mongo-cxx-driver-r3.4.0
  3 cd mongo-cxx-driver-r3.4.0/build
  4 
  5 
  6 CMake: (此处需要安装git sudo apt-get install git)
  7 	cmake -DCMAKE_BUILD_TYPE=Release \
  8 	-DBSONCXX_POLY_USE_MNMLSTC=1 \
  9 	-DCMAKE_INSTALL_PREFIX=/usr/local \
 10 	-DLIBBSON_DIR=/usr/local/lib \
 11 	-DLIBMONGOC_DIR=/usr/local/lib ..
 12 
 13 	sudo make EP_mnmlstc_core 
 14 	make && sudo make install

测试文件编译(CMake)

  1 cmake_minimum_required(VERSION 2.6)
  2 project(test)
  3 
  4 
  5 set(CMAKE_BUILD_TYPE "Debug")
  6 set(CMAKE_CXX_FLAGS_DEBUG "$ENV{CXXFLAGS} -O0 -Wall -g -ggdb")
  7 set(CMAKE_CXX_FLAGS_RELEASE "$ENV{CXXFLAGS} -O3 -Wall")
  8 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
  9 set(CMAKE_VERBOSE_MAKEFILE ON)
 10 
 11 
 12 
 13 include_directories(/usr/local/include/bsoncxx/v_noabi /usr/local/include/mongocxx/v_noabi)
 14 
 15 add_executable(test_example test.cpp)
 16 
 17 target_link_libraries(test_example bsoncxx mongocxx)
 18

常见错误

编译未通过

./test_example: error while loading shared libraries: libbsoncxx.so._noabi: cannot open shared object file: No such file or directory

mongoc driver 路径系统未读到，手动链接库到 /etc/profile 重启bash 生效

LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

CPATH=$CPATH:/usr/local/include/libmongoc-1.0:/usr/local/include/libbson-1.0:/usr/local/include/bsoncxx/v_noabi:/usr/local/include/mongocxx/v_noabi
export CPATH

CMAKE_PREFIX_PATH=/usr/local/lib.libbson-1.0
export CMAKE_PREFIX_PATH

测试代码

  1 #include <iostream>
  2 
  3 #include <bsoncxx/builder/stream/document.hpp>
  4 #include <bsoncxx/json.hpp>
  5 
  6 #include <mongocxx/client.hpp>
  7 #include <mongocxx/instance.hpp>
  8 
  9 int main(int, char**) {
 10     mongocxx::instance inst{};
 11     mongocxx::client conn{mongocxx::uri{}};
 12 
 13     bsoncxx::builder::stream::document document{};
 14 
 15     auto collection = conn["testdb"]["testcollection"];
 16     document << "hello" << "world";
 17 
 18     collection.insert_one(document.view());
 19     auto cursor = collection.find({});
 20 
 21     for (auto&& doc : cursor) {
 22         std::cout << bsoncxx::to_json(doc) << std::endl;
 23     }
 24 }

测试成功

{ "_id" : { "$oid" : "5ce27103177e415851716ee2" }, "hello" : "world" }
