Don't worry, all help is welcome even if it overlooks some part of the question ;)

Perfect... that seems to be exactly what I'm looking for... unfortunately the good config breaks the compilation :) (my fault this time) ;) Only using catkin 0.5.79 so I'll use the first option.

install(DIRECTORY ${CATKIN_DEVEL_PREFIX}/${CATKIN_PACKAGE_INCLUDE_DESTINATION} DESTINATION ${CATKIN_GLOBAL_INCLUDE_DESTINATION} FILES_MATCHING PATTERN "*.h" PATTERN "*.hpp" PATTERN ".svn" EXCLUDE )

So your suggestion is to place the generated header files in the src directory? I've thought about that but usualy compiletime generated files go to the build directory. The install step works fine, I install to *sorry next comment*

Thanks for the answer. I put it on that folder for that reason. However, if devel is not sourced yet (because it doesn't exist) the header will not be seen by the packages. You have to: catkin_make; source devel/setup.bash; catkin_make It works, but it is not elegant ;)

Sorry for the delay in replying. The problem was with packer, I changed to yaourt and everything worked perfectly.

I have the following CMakeLists.txt

cmake_minimum_required(VERSION 2.8.3)
project(datatypes)

find_package(catkin REQUIRED)
catkin_package(
->INCLUDE_DIRS ${CATKIN_DEVEL_PREFIX}/${CATKIN_GLOBAL_INCLUDE_DESTINATION}
#  LIBRARIES rtdb_config
#  CATKIN_DEPENDS other_catkin_pkg
#  DEPENDS system_lib
)

file(MAKE_DIRECTORY ${CATKIN_DEVEL_PREFIX}/${CATKIN_PACKAGE_INCLUDE_DESTINATION})
FILE(GLOB DATATYPE_RAW ${PROJECT_SOURCE_DIR}/datatypes/*)
add_custom_target(${PROJECT_NAME}
    ALL
    COMMAND generate_some_header_files_to ${CATKIN_DEVEL_PREFIX}/${CATKIN_PACKAGE_INCLUDE_DESTINATION}
    SOURCES ${DATATYPE_RAW}
)

Where the custom command generates header files to be used by other packages in the dir ${CATKIN_DEVEL_PREFIX}/${CATKIN_PACKAGE_INCLUDE_DESTINATION}. (Not sure this dir should be used!!)

The problem seems to be that since this directory was still not created it fails to be exported by catkin_package:

catkin_package() include dir '/home/.../devel/include' is neither an absolute directory nor exists relative to '/home/.../src/rtdb/src/datatypes'

Now the question: Where should generated header files be generated to? How can I then export them with catkin?

Thanks in advance.

Just installed using this (much better ;) ) method... However I ran insto some dependencies not being met: ros-comm cannot resolve genmsg, and genmsg does require catkin for building (and does not ask for the dependency). Edit: Wrote too soon, there are some "Could not resolve all dependencies".

This is more a "how did I do it" than a "how do you do it".

The following sequence worked for me. By mixing the instructions from the groovy setup with the instructions from Install from source this is what I did. Note that there are some missing steps (related to dependencies that are on the official reps).

Any comments on better ways to do this are welcome :)
