OPC UA open62541历史数据读取客户端未编译

【中文标题】OPC UA open62541历史数据读取客户端未编译【英文标题】：The OPC UA open62541 historical data reading client is not compiled 【发布时间】：2022-01-12 23:09:34 【问题描述】：

在图书馆的网站上，文档提供了functions for accessing historical data reading 的选项。还有一个example 在存储库中使用历史数据读取。我已经从存储库中简化了这个示例，但我仍然无法编译它。

#include <open62541/client_config_default.h>
#include <open62541/client_highlevel.h>

#include <stdio.h>
#include <stdlib.h>

static UA_Boolean readHist(UA_Client *client, const UA_NodeId *nodeId, UA_Boolean moreDataAvailable, const UA_ExtensionObject *data, void *unused)

    printf("\nRead historical callback:\n");
    printf("\tHas more data:\t%d\n\n", moreDataAvailable);

    return true;


int main(int argc, char *argv[])

    UA_Client *client = UA_Client_new();
    UA_ClientConfig_setDefault(UA_Client_getConfig(client));

    UA_StatusCode retval = UA_Client_connect(client, "opc.tcp://localhost:62544");
    if (retval != UA_STATUSCODE_GOOD)
    
        UA_Client_delete(client);
        return EXIT_FAILURE;
    

    UA_NodeId node = UA_NODEID_STRING(1, "MyTag");

    retval = UA_Client_HistoryRead_raw(client, &node, readHist, UA_DateTime_fromUnixTime(0), UA_DateTime_now(), UA_STRING_NULL, false, 10, UA_TIMESTAMPSTORETURN_BOTH, (void*) UA_FALSE);

    if (retval != UA_STATUSCODE_GOOD)
    
        printf("Failed. %s\n", UA_StatusCode_name(retval));
    

    UA_Client_disconnect(client);
    UA_Client_delete(client);
    return retval == UA_STATUSCODE_GOOD ? EXIT_SUCCESS : EXIT_FAILURE;

编译结果：

在编译时，它会输出类似这样的错误，这些错误指的是没有类型声明的文件“client.cpp”。

我什至不知道需要做什么。我正在尝试编译开发人员提供的示例，但即使它也无法编译。这是一个错误，一个缺陷，还是我做错了什么？实现一种通过 OPC UA 读取历史数据的方法是非常有必要的。我请求帮助解决这个问题。

我的工具：

Windows 10 MSYS2 (MinGW) Eclipse IDE open62541 (v1.2.3)

更新

所以，我重建了分支库 1.2。构建成功：

【问题讨论】：

【参考方案1】：

为了使读取历史数据的机制起作用，需要启用 UA_ENABLE_HISTORIZING 参数WHEN BUILDING THE LIBRARY，该参数未在库的the official documentation 中指定。

cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUA_ENABLE_HISTORIZING=ON -DUA_NAMESPACE_ZERO=FULL ..
