这个错误通常是由于缺少相关的头文件或库文件导致的。请确认您是否已经包含了正确的头文件,并且已经链接了正确的库文件。
如果您使用的是 Google Earth API,请确保您已经正确地包含了 `kmldom.h` 头文件,并且已经链接了 `googleearth.lib` 库文件。
如果您使用的是 Google Earth Pro,请确保您已经正确地包含了 `kmldom.h` 头文件,并且已经链接了 `libkml.lib` 或 `libkmlbase.lib` 库文件。
如果您使用的是其他第三方库,请根据文档或示例代码中的要求进行相关的设置和链接。如果问题仍然存在,请尝试检查您的环境设置和文件路径是否正确。

好的,我可以帮您将这段代码修改为ROS节点。首先,我们需要包含ROS所需的头文件,例如:
```cpp
#include <ros/ros.h>
```
然后,我们需要在main函数中初始化ROS节点:
```cpp
int main(int argc, char** argv) {
ros::init(argc, argv, "log_manager_node");
ros::NodeHandle nh;
// ...
return 0;
}
```
接下来,我们需要将定时任务和日志删除任务分别封装为ROS的定时器和服务。在main函数中,我们可以这样定义一个定时器:
```cpp
ros::Timer timer = nh.createTimer(ros::Duration(60.0), timerCallback);
```
其中,`timerCallback` 是一个你需要定义的回调函数,它将在每隔60秒被定时器调用一次。在回调函数中,你可以像之前的代码一样执行创建文件夹和检查日志大小的任务。
同样地,我们可以定义一个ROS服务来执行删除任务。我们需要在main函数中定义一个服务服务器:
```cpp
ros::ServiceServer delete_logs_server = nh.advertiseService("delete_logs", deleteLogsCallback);
```
其中,`deleteLogsCallback` 是一个你需要定义的服务回调函数,它将在收到删除日志服务请求时被调用。在回调函数中,你可以像之前的代码一样执行删除日志的任务。
最后,完整的ROS节点代码如下:
```cpp
#include <ros/ros.h>
#include <ctime>
#include <chrono>
#include <string>
#include <filesystem>
#include <fstream>
#include <sstream>
#include <thread>

void create_folder(std::string folder_name) {
boost::filesystem::create_directory(folder_name);
std::string sub_foldername = folder_name + "/logs_ros";
boost::filesystem::create_directory(sub_foldername);
}
std::string get_current_time() {
auto now = std::chrono::system_clock::now();
std::time_t now_c = std::chrono::system_clock::to_time_t(now);
std::tm parts = *std::localtime(&now_c);
char buffer[20];
std::strftime(buffer, sizeof(buffer), "%Y-%m-%d-%H-%M", &parts);
return buffer;
}
void check_logs_size() {
std::string logs_path = "/home/sage/logs/";
boost::filesystem::path logs_dir(logs_path);
std::uintmax_t total_size = 0;
for (const auto& file : boost::filesystem::recursive_directory_iterator(logs_dir)) {
if (boost::filesystem::is_regular_file(file)) {
total_size += boost::filesystem::file_size(file);
}
}
if (total_size > MAX_LOGS_SIZE) {
boost::filesystem::path earliest_dir;
std::time_t earliest_time = std::time(nullptr);
for (const auto& dir : boost::filesystem::directory_iterator(logs_dir)) {
if (boost::filesystem::is_directory(dir)) {
std::string dir_name = dir.path().filename().string();
std::tm time_parts = {};
std::istringstream ss(dir_name);
std::string part;
std::getline(ss, part, '-');
time_parts.tm_year = std::stoi(part) - 1900;
std::getline(ss, part, '-');
time_parts.tm_mon = std::stoi(part) - 1;
std::getline(ss, part, '-');
time_parts.tm_mday = std::stoi(part);
std::getline(ss, part, '-');
time_parts.tm_hour = std::stoi(part);
std::getline(ss, part, '-');
time_parts.tm_min = std::stoi(part);
std::time_t dir_time = std::mktime(&time_parts);
if (dir_time < earliest_time) {
earliest_time = dir_time;
earliest_dir = dir.path();
}
}
}
if (!earliest_dir.empty()) {
boost::filesystem::remove_all(earliest_dir);
}
}
}
void timerCallback(const ros::TimerEvent& event) {
std::string logs_path = "/home/sage/logs/";
std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
std::time_t now_c = std::chrono::system_clock::to_time_t(now);
std::tm parts = *std::localtime(&now_c);
if (parts.tm_min % 10 == 0) {
std::string folder_name = logs_path + get_current_time();
create_folder(folder_name);
}
check_logs_size();
}
bool deleteLogsCallback(std_srvs::Empty::Request& req, std_srvs::Empty::Response& res) {
std::string logs_path = "/home/sage/logs/";
boost::filesystem::path logs_dir(logs_path);
boost::filesystem::remove_all(logs_dir);
return true;
}
int main(int argc, char** argv) {
ros::init(argc, argv, "log_manager_node");
ros::NodeHandle nh;
ros::Timer timer = nh.createTimer(ros::Duration(60.0), timerCallback);
ros::ServiceServer delete_logs_server = nh.advertiseService("delete_logs", deleteLogsCallback);
ros::spin();
return 0;
}
```
在这个节点中,我们定义了一个名为 `log_manager_node` 的ROS节点,并在其中实现了一个定时器和一个服务。定时器每隔60秒检查一次日志大小并创建新的日志文件夹,服务则用于删除所有日志文件。

要读取上述YAML文件,您可以使用适合的YAML解析库,例如YAML-CPP或YAMLCPP-Parser。下面是使用YAML-CPP的示例代码:
```cpp
#include <iostream>
#include <yaml-cpp/yaml.h>
int main() {
// 加载YAML文件
YAML::Node config = YAML::LoadFile("common.yaml");
// 读取msg_source字段的值
int msgSource = config["msg_source"].as<int>();
std::cout << "msg_source: " << msgSource << std::endl;
// 读取send_msg_ros字段的值
bool sendMsgRos = config["send_msg_ros"].as<bool>();
std::cout << "send_msg_ros: " << std::boolalpha << sendMsgRos << std::endl;
// 读取send_msg_proto字段的值
bool sendMsgProto = config["send_msg_proto"].as<bool>();
std::cout << "send_msg_proto: " << std::boolalpha << sendMsgProto << std::endl;
// 读取camera_number字段的值
int cameraNumber = config["camera_number"].as<int>();
std::cout << "camera_number: " << cameraNumber << std::endl;
// 读取camera_paths字段的值
YAML::Node cameraPaths = config["camera_paths"];
for (const auto& camera : cameraPaths) {
std::string cameraName = camera.first.as<std::string>();
std::string includePath = camera.second["include"].as<std::string>();
std::cout << "camera name: " << cameraName << ", include path: " << includePath << std::endl;
}
return 0;
}
```
请确保将上述示例代码与YAML-CPP库一起编译,链接并运行。从YAML文件中读取的值将打印到控制台上。
