p1ex's Issues

Test issue

p1ex/src/navigation.cpp

Line 22 in 263d6ae

cout << "You have entered wrong "<< dimension <<" input." << endl;

Wrong node name

p1ex/CMakeLists.txt

Line 154 in 5d2767a

add_executable(${PROJECT_NAME} two

The executable for navigation.cpp is named "two", but ${PROJECT_NAME} which is infront means that you add the projects name aswell in the executable name. So the full executable name is "p1ex two"
This needs to be written every time you want to call the executable:

p1ex/CMakeLists.txt

Lines 158 to 159 in 5d2767a

	add_dependencies(two ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
	target_link_libraries(two myLib ${catkin_LIBRARIES})

p1ex/CMakeLists.txt

Line 195 in 5d2767a

install(TARGETS two

p1ex/launch/navi.launch

Line 5 in 5d2767a

<node pkg="p1ex" name="two" type="two" output="screen"/>

Turtlesim not included

We will be using turtlesim. Therefore we need to include "turtlesim" here.

p1ex/CMakeLists.txt

Line 16 in 5d2767a

find_package(catkin REQUIRED COMPONENTS

And here, as a dependency.

p1ex/package.xml

Line 51 in 5d2767a

<buildtool_depend>catkin</buildtool_depend>

Skal have det sidste tal ud af dettet :/

Hvordan får jeg det sidste tal ud af dette?

p1ex/src/map.cpp

Lines 13 to 15 in 7e981d4

	void lis(const std_msgs::String::ConstPtr& msg){
	ROS_INFO("I heard: [%s]", msg->data.c_str());
	}

No directory included

Uncomment # ${catkin_INCLUDE_DIRS} as this is directory we need to include.

Kunne godt bruge lidt hjælp her

Hvordan får jeg den her til at subscribe til navi/navigation.cpp filen?

p1ex/src/map.cpp

Line 27 in 3f905ad

ros::Subscriber lengt = nh.subscribe("leng", 10, lis);

No directory includes.

p1ex/CMakeLists.txt

Lines 122 to 125 in 5d2767a

	include_directories(
	# include
	# ${catkin_INCLUDE_DIRS}
	)

The ${catkin_INCLUDE_DIRS} needs to be included

No "mylib" library.

p1ex/CMakeLists.txt

Line 144 in 5d2767a

target_link_libraries(node_one myLib ${catkin_LIBRARIES})

p1ex/CMakeLists.txt

Line 159 in 5d2767a

target_link_libraries(two myLib ${catkin_LIBRARIES})

Both refer to a library "mylib", that we do not use and have not yet declared.

Og modsat med det her:

Hvordan får jeg det her til at publish tallene til den anden node? Tror jeg har gjort det helt forkert...

p1ex/src/navigation.cpp

Lines 31 to 35 in 3f905ad

	std_msgs::String msg;
	std::stringstream msglen;
	msglen << width,length << count;
	msg.data = msglen.str();
	len_pub.publish(msg);
