Building and linking ros library

edit

Hi All,

I'm trying to rosbuild a library, which will then be included in several other ROS-packages. Right now, I have successfully created the library in "DeviceHandler" package by:

rosbuild_add_library(Advertiser src/Advertiser.cpp)

This library consists of a class (Advertiser.cpp and Advertiser.hpp) I have exported the following flags in the Manifest.xml of "DeviceHandler":

<export>
<cpp cflags="-I${prefix} -I${prefix}/include/ -I${prefix}/include/DeviceHandler/ -I${prefix}/msg_gen/cpp/include/DeviceHandler -I${prefix}/srv_gen/cpp/include/DeviceHandler" lflags="-Wl,-rpath,${prefix}/lib -L${prefix}/lib -lAdvertiser"/>
</export>

And I have made my new package (let's call it NewPackage) depend on this "DeviceHandler" package - which builds the "libAdvertiser.so".

So far so good, however, when I try to utilise the library (libAdvertiser.so) in the "NewPackage", it simply can't find "Advertiser.hpp" when included inside code.

Inside my main.cpp in "NewPackage" I have:

#include "Advertiser.hpp"

And the compiler fails on this one, with the output:

/home/casper/ros_workspace/MobileManipulator/hardware_reconfig_system/DeviceEmulators/src/GripperEmulator.cpp:26:26: fatal error: Advertiser.hpp: No such file or directory

The DeviceHandler package both builds the library + an executable, but is that the problem?

Also, should I do anything in the CMakeList.txt of "NewPackage" in order to link the library?

I have been searching for a couple of hours for an answer and nothing really seemed to do the trick. Hoping that it is just some detail I'm missing, any help is much appreciated.

Thanks /Casper
