Deepin编译安装 mongoc++ 驱动程序
本文为在Deepin20.9环境下安装mongoc++驱动的过程记录。
一、安装环境：
操作系统：Deepin 20.9
mongo版本：docker mongoDB 5.0.17
gcc版本：12.2.0 默认支持C++17 要求C++11及以上
cmake版本：3.24.2 要求3.2及以上
openssl版本：1.1.1d17 要求1.1及以上
查看下表支持mongoDB5.0的mongocxx-driver驱动版本为3.7
二、安装MongoDB C驱动
1、libmongoc版本要求
Mongoc++驱动程序建立在 MongoDB C 驱动之上，mongocxx-3.7.x需要libmongoc 1.22.1 或更高版本。
2、优先选择包管理器安装
（1）检查包管理器提供的libmongoc版本
$ apt list libmongoc*
正在列表... 完成
libmongoc-1.0-0/未知,now 1.14.0-1 amd64 [已安装]
libmongoc-1.0-0/未知 1.14.0-1 i386
libmongoc-dev/未知,now 1.14.0-1 amd64 [已安装]
libmongoc-dev/未知 1.14.0-1 i386
libmongoc-doc/未知,未知,now 1.14.0-1 all [已安装]
libmongoclient-dev/未知 1.1.3-3 amd64
libmongoclient-dev/未知 1.1.3-3 i386
libmongoclient0/未知 1.1.3-3 amd64
libmongoclient0/未知 1.1.3-3 i386
$
（2）如果包管理器提供的libmongoc版本>1.22.1，则使用包管理器安装：
$ sudo apt install libmongoc-1.* libbson-1.*
（3）此处包管理器提供的libmongoc版本为1.14.0-1<1.22.1，则需要下载最新的源代码构建。
3、源代码构建安装
(1)准备源代码
①查看最新源代码版本
查看URL地址：
https://github.com/mongodb/mongo-c-driver/releases
经查mongoc当前最新版本为1.23.4。
②下载mongo-c-driver源代码
$ wget https://github.com/mongodb/mongo-c-driver/releases/download/ 1.23.4/mongo-c-driver-1.23.4.tar.gz

$
③解压源代码包
$ tar xzf mongo-c-driver-1.23.4.tar.gz
(2)准备构建环境
$ sudo sh -c 'curl -s --location https://www.mongodb.org/static/pgp/libmongocrypt.asc | gpg --dearmor >/etc/apt/trusted.gpg.d/libmongocrypt.gpg'
echo "deb https://libmongocrypt.s3.amazonaws.com/apt/debian buster/libmongocrypt/1.7 main" | sudo tee /etc/apt/sources.list.d/libmongocrypt.list
$ sudo apt update
$ sudo apt install lld glibc-source gawk bison libzstd-dev libssl-dev libsasl2-dev libmongocrypt-dev
(3)构建安装libmongoc
默认安装到目录/usr/local下，即包在/usr/local/lib下，头文件在/usr/local/include下。
$ cd mongo-c-driver-1.23.4
$ mkdir cmake-build
$ cd cmake-build
$ cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..
......
$ make
......
$ sudo make install
......

三、编译安装mongoc++驱动
1、下载mongoc++源代码
①查看最新mongoc++驱动版本
查看URL地址：
https://github.com/mongodb/mongo-cxx-driver/releases
最新mongoc++驱动版本为3.7.1：
②下载mongoc++驱动
$ curl -OL https://github.com/mongodb/mongo-cxx-driver/releases/download/r3.7.1/mongo-cxx-driver-r3.7.1.tar.gz

$
③解压源代码包
$ tar -xzf mongo-cxx-driver-r3.7.1.tar.gz
$ cd mongo-cxx-driver-r3.7.1/build
2、配置构建
(1)构建选项说明
指定构建类型
-DCMAKE_BUILD_TYPE=｛[RelWithDebInfo]|Release|Debug｝
RelWithDebInfo 默认构建带调试的发布包
Release 构建发布包
Debug 构建调试包
指定依赖的mongoc驱动库路径，当有多个依赖库路径时，用分号分隔并用双引号包括。
-DCMAKE_PREFIX_PATH=<依赖mongo-c库路径>
指定mongocxx驱动库的安装路径
-DCMAKE_INSTALL_PREFIX=
指定mongocxx驱动库的非标准安装路径
-DCMAKE_INSTALL_RPATH=
指定同时构建动态和静态库，默认只构建动态库
-DBUILD_SHARED_AND_STATIC_LIBS=ON
例：安装到标准路径/usr/local
cmake .. -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local
例：安装到非标准路径/opt/mongo
cmake .. -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/opt/mongo \
-DCMAKE_INSTALL_RPATH=/opt/mongo
例：构建时指定libmongoc路径/opt/mongo-c-driver和mongocxx安装路径/opt/mongo-cxx-driver
cmake .. -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_PREFIX_PATH=/opt/mongo-c-driver \
