Visual Studio 2017 编译 mongo-c-driver 库

运行环境：
操作系统：windows 10 64
IDE: Visual Studio 2017
编译工具：CMake 3.16.2 windows 64
MongoDB Server：MongoDB 5.0.13 windows 64
MongoDB 管理工具：MongoDB Compass 1.33.1 windows 64

一、mongo-c-driver库的编译

❤ 第一步：下载

GitHub下载地址：https://github.com/mongodb/mongo-c-driver/archive/refs/heads/master.zip

❤ 第二步：CMake

解压 mongo-c-driver-master.zip，进入mongo-c-driver-master文件夹并创建文件夹：build-vs2017

打开CMake，选择编译文件夹和输出文件夹

(注意：必须设置版本号，否则可能编译失败)

❤ 第三步：Visual Studio 2017 编译

进入：mongo-c-driver-master\build-2017打开 mongo-c-driver.sln工程文件

在：D:\temp\mongo-c-driver目录下生成编译结果

二、mongo-c-driver库的简单使用

❤ 启动MongoDB Server，打开MongoDB Compass工具

❤ Visual Studio 2017新建项目，配置项目环境：

将D:\temp\mongo-c-driver\include 和 D:\temp\mongo-c-driver\lib 两个文件夹复制到项目目录下，再将include目录下的两个文件夹改名：libbson-1.0 --> bson 、libmongoc-1.0 --> mongoc

包含头文件目录

包含库目录

包含具体库文件

❤ 创建源文件，复制官方例子: http://mongoc.org/libmongoc/current/tutorial.html#include-and-link-libmongoc-in-your-c-program

#include <mongoc/mongoc.h>

int
main(int argc, char *argv[])
{
	const char *uri_string = "mongodb://localhost:27017";
	mongoc_uri_t *uri;
	mongoc_client_t *client;
	mongoc_database_t *database;
	mongoc_collection_t *collection;
	bson_t *command, reply, *insert;
	bson_error_t error;
	char *str;
	bool retval;

	/*
	 * Required to initialize libmongoc's internals
	 */
	mongoc_init();

	/*
	 * Optionally get MongoDB URI from command line
	 */
	if (argc > 1) {
		uri_string = argv[1];
	}

	/*
	 * Safely create a MongoDB URI object from the given string
	 */
	uri = mongoc_uri_new_with_error(uri_string, &error);
	if (!uri) {
		fprintf(stderr,
			"failed to parse URI: %s\n"
			"error message:       %s\n",
			uri_string,
			error.message);
		return EXIT_FAILURE;
	}

	/*
	 * Create a new client instance
	 */
	client = mongoc_client_new_from_uri(uri);
	if (!client) {
		return EXIT_FAILURE;
	}

	/*
	 * Register the application name so we can track it in the profile logs
	 * on the server. This can also be done from the URI (see other examples).
	 */
	mongoc_client_set_appname(client, "connect-example");

	/*
	 * Get a handle on the database "db_name" and collection "coll_name"
	 */
	database = mongoc_client_get_database(client, "db_name");
	collection = mongoc_client_get_collection(client, "db_name", "coll_name");

	/*
	 * Do work. This example pings the database, prints the result as JSON and
	 * performs an insert
	 */
	command = BCON_NEW("ping", BCON_INT32(1));

	retval = mongoc_client_command_simple(
		client, "admin", command, NULL, &reply, &error);

	if (!retval) {
		fprintf(stderr, "%s\n", error.message);
		return EXIT_FAILURE;
	}

	str = bson_as_json(&reply, NULL);
	printf("%s\n", str);

	insert = BCON_NEW("hello", BCON_UTF8("world"));

	if (!mongoc_collection_insert_one(collection, insert, NULL, NULL, &error)) {
		fprintf(stderr, "%s\n", error.message);
	}

	bson_destroy(insert);
	bson_destroy(&reply);
	bson_destroy(command);
	bson_free(str);

	/*
	 * Release our handles and clean up libmongoc
	 */
	mongoc_collection_destroy(collection);
	mongoc_database_destroy(database);
	mongoc_uri_destroy(uri);
	mongoc_client_destroy(client);
	mongoc_cleanup();

	return EXIT_SUCCESS;
}

编译、运行...（第一次会出错，原因：找不到.dll文件）
将D:\temp\mongo-c-driver\bin目录下的文件全部复制到Mongodb_Client_Project\Debug下，即复制到.exe文件所在路径

再次编译、运行...
