compile error with tf transformation [closed]

Hi everybody,

I have written some codes as below:

#include <ros/ros.h>
#include <tf/transform_broadcaster.h>
#include <nav_msgs/Odometry.h>
int main(int argc,char ** argv){
    ros::NodeHandle n;
    ros::Publisher pubOdom= n.advertise<nav_msgs::Odometry>("odom",50);
    tf::TransformBroadcaster odomBroadcaster;
    //some other codes
    ros::Rate r(10);
        //some other codes
    return 0;

and put

rosbuild_add_executable(OdomOFPS1_X64 src/OdomOFPS1.cpp)

in the end of the "CMakeLists.txt" file.

There is an error when compile:

OdomOFPS1.cpp.o: In function `main':
src/OdomOFPS1.cpp:22: undefined reference to `tf::TransformBroadcaster::TransformBroadcaster()'
src/OdomOFPS1.cpp:127: undefined reference to `tf::TransformBroadcaster::sendTransform(geometry_msgs::TransformStamped_<std::allocator<void> > const&)'
collect2: error: ld returned 1 exit status

It seems like a link error,the compiler could not find the "tf::TransformBroadcaster" class.Should I put the source code of the tf package in my project and compile them together or solve this problem by some other way?

You need to link the executable against the tf libraries which are installed on your system. There's documentation of how to do that for rosbuild here

I have solved this problem by adding "target_link_libraries(OdomOFPS1_R32 tf)" in the "CMakeLists.txt" file. It seems like that the compiler linked the shared object file in the lib directory.

Isn't it enough to add dependency to tf package in manifest.xml? As I understand rosbuild_init() in CMakeLists.txt will take care of these dependencies, when rosbuild_add_executable() is used.

Should I add <depend package="tf"/> into the manifest.xml? I will try,thank you very much!

I made a package from scratch and it did work with just a dependency, so it should be enough. Anyway, I guess you have tried it already :)
