[英]ROS noetic, fatal error: ros/ros.h: No such file or directory
[英]ROS rosmake error
我目前正在與ROS合作進行項目。 我對ROS及其功能完全陌生。 目前,我正在編寫有關ROS的教程,並且是第一次開始使用代碼。 盡管我確實有使用c ++的經驗,但我不知道出了什么問題。 在ROS中,我使用rosmake命令,但無法編譯cpp文件/代碼。 誰能幫助我找出錯誤發生的原因? (以及可能如何解決?)
以下是cpp文件代碼:
#include "ros/ros.h"
#include "std_msgs/String.h"
#include <sstream>
int main(int argc, char **argv)
{
ros::init(argc, argv, "example1_a");
ros::NodeHandle n;
ros::Publisher chatter_pub = n.advertise<std_
msgs::String>("message", 1000);
ros::Rate loop_rate(10);
while (ros::ok())
{
std_msgs::String msg;
std::stringstream ss;
ss << " I am the example1_a node ";
msg.data = ss.str();
//ROS_INFO("%s", msg.data.c_str());
chatter_pub.publish(msg);
ros::spinOnce();
loop_rate.sleep();
}
return 0;
}
這里是構建日志:

接下來的代碼來自第二個文件,該文件會編譯並且不會產生任何錯誤:
#include "ros/ros.h"
#include "std_msgs/String.h"
void chatterCallback(const std_msgs::String::ConstPtr& msg)
{
ROS_INFO("I heard: [%s]", msg->data.c_str());
}
int main(int argc, char **argv)
{
ros::init(argc, argv, "example1_b");
ros::NodeHandle n;
ros::Subscriber sub = n.subscribe("message", 1000, chatterCallback);
ros::spin();
return 0;
}
C ++代碼中的換行符只能通過3種方式完成:
cout<<"Error:This is a really long error "
"message that exceeds the maximum permitted length.\n";
要么
cout<<"Error:This is a really long error \
message that exceeds the maximum permitted length.\n";
要么
c\
o\
u\
t<<"Error:This is a really long error \
message that exceeds the maximum permitted length.\n";
除此之外,它還會引發錯誤...
更改:
ros::Publisher chatter_pub = n.advertise<std_
msgs::String>("message", 1000);
通過:
ros::Publisher chatter_pub = n.advertise<std_msgs::String>("message", 1000);
PS: 您不應該使用rosmake 。 這是用於構建工作區的舊工具。
使用 catkin_make
或catkin_make
catkin build
。
注意:不能在同一工作空間上同時使用catkin_make和catkin 構建 。 如果要切換,則需要清理工作區。 為此,您必須刪除工作區文件夾中的構建,開發和安裝目錄。
$ cd ~/catkin_ws
$ sudo rm -r devel build install
替代方式:
如果您使用catkin_make並希望清理工作區以切換到catkin構建使用
$ catkin_make clean
$ catkin build
如果您使用catkin build並希望清理工作區以切換到catkin_make使用
$ catkin clean
$ catkin_make
羅斯馬克vs卡特金:
由於ROS Groovy,因此不建議使用rosmake,這就是為什么我們使用柔cat花色的原因:
catkin_make vs catkin build :
差不多,但最新的柔kin花序 。 如今,有人建議從catkin_make切換到catkin build 。 兩者之間的主要區別在於,catkin構建具有更好的隔離包。 它將為每個包構建一個工作區。
使用C ++ 11制作項目。 為此,請在命令中使用cmake標志:
catkin_make -DCMAKE_CXX_FLAGS=-std=c++11
要么
catkin build -DCMAKE_CXX_FLAGS=-std=c++11
