undefined reference to `ros::Publisher::isLatched() const

Question

Is the method not implemented or am I missing something in the linking?

(rosccp)

ros fuerte on ubuntu 12.04

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)

# Set the build type.  Options are:

#  RelWithDebInfo : w/ debug symbols, w/ optimization
#  MinSizeRel     : w/o debug symbols, w/ optimization, stripped binaries
#set(ROS_BUILD_TYPE RelWithDebInfo)

rosbuild_init()

#set the default path for built executables to the "bin" directory

Could you include the version of ROS you are using, your Ubuntu version, your manifest.xml file and your CMakeLists.txt ?

Please also copy-paste the complete error output.

Answer 1

It appears that this may actually be a bug, as I was able to reproduce it on my Fuerte/12.04 install as well.

It seems that while it is documented in the API, and there is a declaration in the header file, but it does not seem that the method is actually implemented anywhere. This explains why you would see a linker error.

I filed a ticket on code.ros.org so that this can get resolved.
