Hi, I am trying to write my own ros library. Just a ROS package containing a .hpp, a .cpp and the compiled library of the cpp.

I put the cpp inside the src folder, the hpp into the include directory and added the add_library command to the CMakeLists.txt, and the shared object file is created. But now I want to get this library used by another package. I added the library package to its manifest.xml. And it does not find the header file of the library package. I can make it link the library with multiple commands in the CMakeLists but then I still do not get the header file.

I found a tutorial on github: Tutorial

It says that something needs to be added to the manifest.xml, but unfortunately the line telling that is missing. (The line was removed because of the tags I guess)

I guessed it might be the <export> tag like this:
 <export>
    <cpp cflags="-I${prefix}/include/ -I${prefix}/include/NameOfLib" lflags="-L${prefix}/lib -Wl,-rpath,${prefix}/lib -lNameOfLib"/> 
  </export>

But it doesn't work.

Can anybody help me with that?

Thanks.

Got it! Must be related to old compilation data, I am using the cmake extensions for Eclipse and I deleted CMakeCache.txt cmake_install.cmake and the directory CMakeFiles and recompiled everything, now it seems to work.

Did you also set set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib) in your CMakeLists.txt?

Of course in the Manifest.xml file of the other package you want to use this library you add somethings like <depend package="NameOfLib"> so it goes and grabs that <export> tag.

I created the package with roscreate-pkg, so yes it's set. I also did the same with the other package referencing the library package in the manifest, but it still does not work.
