MongoDb Windows 环境下 c++ driver 安装流程

1. 安装boost 1.60
   位置: c:\boost_1_60_0

2. 下载安装mongo c dirver
   http://mongoc.org/?jmp=docs#documentation
   http://mongoc.org/libmongoc/current/installing.html
   Building on Windows

   先编译 libbson
   进入libsson的目录:
   cd mongo-c-driver-1.9.5\src\libbson
   mongo-c-driver-1.9.5是安装压缩包的解压目录

   cmake 创建 libbson 的编译环境
   “c:\Program Files\CMake\bin\cmake.exe” -G “Visual Studio 15 2017 Win64” “-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver” “-DCMAKE_BUILD_TYPE=Release”
   注意这里确定了cmake的详细路径, Visual Studio 的版本.

   完成了cmake创建编译环境后,开始正式编译 libbson
   msbuild.exe /p:Configuration=Release ALL_BUILD.vcxproj
   msbuild.exe /p:Configuration=Release INSTALL.vcxproj

   下面进入mongo c driver的目录:
   cd mongo-c-driver-1.9.5

   cmake 创建 mongo c driver 的编译环境
   “c:\Program Files\CMake\bin\cmake.exe” -G “Visual Studio 15 2017 Win64” “-DENABLE_SSL=WINDOWS” “-DENABLE_SASL=SSPI” “-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver” “-DCMAKE_PREFIX_PATH=C:\mongo-c-driver” “-DCMAKE_BUILD_TYPE=Release”

   开始编译 mongo c driver
   msbuild.exe /p:Configuration=Release ALL_BUILD.vcxproj
   msbuild.exe /p:Configuration=Release INSTALL.vcxproj

   最后所有mongo c driver文件安装在C:\mongo-c-driver

3. 下载安装mongo c++ driver
   https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/#installing-the-mongocxx-driver
   git 最新mongo cxx driver
   git clone https://github.com/mongodb/mongo-cxx-driver.git –branch releases/stable –depth 1

   cmake 创建 mongo c++ driver 编译环境
   “c:\Program Files\CMake\bin\cmake.exe” -G “Visual Studio 15 2017 Win64” -DCMAKE_INSTALL_PREFIX=C:\mongo-cxx-driver -DCMAKE_PREFIX_PATH=c:\mongo-c-driver -DBOOST_ROOT=c:\boost_1_60_0
   这里注意Boost路径(“本人电脑为 c:\boost_1_60_0”)必须设置正确。

   开始编译 mongo c++ driver
   msbuild.exe ALL_BUILD.vcxproj
   msbuild.exe INSTALL.vcxproj

4. 修改使用mongodb c++ driver 工程的 vcxproj 文件
   https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/#installing-the-mongocxx-driver
   Compiling with MSVC

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">
    <LinkIncremental>trueLinkIncremental>
    <IncludePath>c:\local\boost_1_59_0\;C:\mongo-cxx-driver\include\mongocxx\v_noabi;C:\mongo-cxx-driver\include\bsoncxx\v_noabi;C:\mongo-c-driver\include\libmongoc-1.0;C:\mongo-c-driver\include\libbson-1.0;$(IncludePath)IncludePath>

1. 工程main.cpp

#include "stdafx.h"
#include 
#include 
#include 

#include 
#include 

int main(int, char**) {
    mongocxx::instance inst{};
    mongocxx::client conn{mongocxx::uri{}};

    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;
    }
}

上面这个工程,本人无法成功编译.
注意根据官方文档 mongocxx::uri{} 实际上等价于 mongocxx::uri(“mongodb://localhost:27017”)
上面这个工程我们编译报错为:

Error   LNK2001 unresolved external symbol "public: static class std::basic_string,class std::allocator > const mongocxx::v_noabi::uri::k_default_uri" (?k_default_uri@uri@v_noabi@mongocxx@@2V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@B)

修改为

    mongocxx::instance inst{};  
    //mongocxx::client conn{ mongocxx::uri{} };
    mongocxx::uri uri("mongodb://localhost:27017");
    mongocxx::client conn{ uri };

成功编译并运行
