Question

Hi all,

Since a few days I have had the following error mesage:

CMake Warning at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:76 (find_package):
  Could not find a package configuration file provided by
  "message_generation" with any of the following names:

    message_generationConfig.cmake
    message_generation-config.cmake

  Add the installation prefix of "message_generation" to CMAKE_PREFIX_PATH or
  set "message_generation_DIR" to a directory containing one of the above
  files.  If "message_generation" provides a separate development package or
  SDK, be sure it has been installed.

I am sure the ros-indigo-message-generation and ros-indigo-message-runtime are installed.

Any idea of what is going on?

Kind regards,

Antoine.

Answer 1

Hi, I get this problem, And fix it. Please attention this point WORD: CMAKE_PREFIX_PATH

now run:

sudo vi  /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake

line 67:

set(paths " ")
foreach(path ${CMAKE_PREFIX_PATH})
  if(IS_DIRECTORY ${path}/share/${component}/cmake)
    list(APPEND paths ${path}/share/${component}/cmake)
  endif()
endforeach()

Please add one line:

 set(paths " ")
 message("Fix The fucking bug: ${CMAKE_PREFIX_PATH}")
 foreach(path ${CMAKE_PREFIX_PATH})
  if(IS_DIRECTORY ${path}/share/${component}/cmake)
    list(APPEND paths ${path}/share/${component}/cmake)
  endif()
endforeach()

You will find the ${CMAKE_PREFIX_PATH} is empty or don't has the /opt/ros/kinetic

So, PLEASE ADD ONE LINE IN YOUR PROJECT CMakeLists.txt

set(CMAKE_PREFIX_PATH "${CMAKE_PREFIX_PATH};/opt/ros/kinetic")

I don't often downvote an answer, but in this case I did.

For two reasons:

message("Fix The fucking bug: ${CMAKE_PREFIX_PATH}")
you should not edit files in /opt/ros. If fixes are needed, propose them upstream. Do not edit files in system locations, as those will be overwritten the next time the package gets updated

Finally: it is very likely the problem described by the OP was also a configuration or setup issue on the side of the OP (ie: his machine or workflow). Notice also the comment posted by @arennuit:

The problem was totally unlinked to ROS, sorry.

Also: manually changing CMAKE_PREFIX_PATH, especially in the file you are doing it, should not and is not needed.

Thank for your suggestion

I also agree your word, The system file shound not be edited. And I just for output the debug information. I git checkout the /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake you just need to add set(CMAKE_PREFIX_PATH "${CMAKE_PREFIX_PATH};/opt/ros/kinetic") in yourself project CMakeLists..txt

However, almost people just want to make their project work.

Before the offical solution of the problem, I think it work.
