呜呜呜呜呜呜~~~，我太菜了，编了一天！！！

把下面的代码跑起来

#include <iostream>
#include <WinSock2.h>
#define __STDC_LIMIT_MACROS  // 添加宏定义
#include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-includes.h>

int main() {
	// 初始化 net-snmp 库
	init_snmp("snmpapp");

	// 创建 SNMP 会话
	netsnmp_session session, *ss;
	snmp_sess_init(&session);
	session.peername = _strdup("localhost");
	session.version = SNMP_VERSION_2c;
	session.community = reinterpret_cast<u_char*>("public");
	session.community_len = strlen(reinterpret_cast<const char*>(session.community));

	ss = snmp_open(&session);
	if (!ss) {
		std::cerr << "Failed to open SNMP session\n";
		return 1;
	}

	// 构造 OID
	oid anOID[MAX_OID_LEN];
	size_t anOID_len = MAX_OID_LEN;
	const char* oidStr = "1.3.6.1.2.1.2.2.1.8.1";  // 示例 OID
	if (!snmp_parse_oid(oidStr, anOID, &anOID_len)) {
		std::cerr << "Failed to parse OID\n";
		snmp_close(ss);
		return 1;
	}

	// 查询交换机状态
	netsnmp_pdu* pdu = snmp_pdu_create(SNMP_MSG_GET);
	snmp_add_null_var(pdu, anOID, anOID_len);
	netsnmp_pdu* response;
	if (snmp_synch_response(ss, pdu, &response) == STAT_SUCCESS) {
		if (response->errstat == SNMP_ERR_NOERROR) {
			for (netsnmp_variable_list* vars = response->variables; vars; vars = vars->next_variable) {
				if (vars->type == ASN_INTEGER) {
					std::cout << "Switch status: " << *(vars->val.integer) << std::endl;
				}
			}
		}
		else {
			std::cerr << "SNMP error: " << snmp_errstring(response->errstat) << std::endl;
		}
		snmp_free_pdu(response);
	}
	else {
		std::cerr << "Failed to get SNMP response\n";
	}

	// 释放资源
	snmp_close(ss);

	return 0;
}
