apt-get install cmake libssl-dev libsasl2-dev

安装编译所需要的软件；如果没有gcc,g++,gdb也请安装好；

wget https://github.com/mongodb/mongo-c-driver/releases/download/1.21.1/mongo-c-driver-1.21.1.tar.gz tar xzf mongo-c-driver-1.21.1.tar.gz cd mongo-c-driver-1.21.1 mkdir cmake-build cd cmake-build cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF .. cmake --build . cmake --build . --target install

curl -OL https://github.com/mongodb/mongo-cxx-driver/releases/download/r3.6.6/mongo-cxx-driver-r3.6.6.tar.gz tar -xzf mongo-cxx-driver-r3.6.6.tar.gz cd mongo-cxx-driver-r3.6.6/build cmake ..??????????????????????????????? \ ??? -DCMAKE_BUILD_TYPE=Release????????? \ ??? -DCMAKE_INSTALL_PREFIX=/usr/local

cmake --build . sudo cmake --build . --target install

写一个测试文件main.cpp

#include <iostream> #include <bsoncxx/builder/stream/document.hpp> #include <bsoncxx/json.hpp> #include <mongocxx/client.hpp> #include <mongocxx/instance.hpp> int main(int, char**) { mongocxx::instance inst{}; //改成你自己的localhost服务器，向testdb写数据 mongocxx::client conn{mongocxx::uri("mongodb://11.21.14.11:27017")}; bsoncxx::builder::stream::document document{}; auto collection = conn["testdb"]["testcollection"]; document << "hello" << "world"; collection.insert_one(document.view()); auto cursor = collection.find({}); for (auto&& doc : cursor) { std::cout << bsoncxx::to_json(doc) << std::endl; } }

编译：

c++ --std=c++11 main.cpp -o main $(pkg-config --cflags --libs libmongocxx)

生成main ldd ./main?? 查看可执行文件需要so库；如果发现.so库not found, export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/ 增加库路径；

用cmake和vscode结合：

在main.cpp同级目录建立：????? CMakeLists.txt

文件内容如下：用于make.

cmake_minimum_required(VERSION 3.15) project(main) set(CMAKE_CXX_STANDARD 14) add_executable(main main.cpp) find_package(libmongocxx REQUIRED) find_package(libbsoncxx REQUIRED) include_directories(${LIBMONGOCXX_INCLUDE_DIR}) include_directories(${LIBBSONCXX_INCLUDE_DIR}) include_directories("/usr/local/include/mongocxx/v_noabi") include_directories("/usr/local/include/bsoncxx/v_noabi") include_directories("/usr/local/include/libmongoc-1.0") include_directories("/usr/local/include/libbson-1.0") include_directories("/usr/local/lib") target_link_libraries(main ${LIBMONGOCXX_LIBRARIES}) target_link_libraries(main ${LIBBSONCXX_LIBRARIES})

然后ctrl+`打开终端： make.

同样生成main ;?? 至此，结束；
