Hi all,

I am working with a double gnulinux/xenomai system. The switch from one to the other is done like Orocos does with the "OROCOS_TARGET" env variable. But When I have a package depending of another, I need to define 2 different manifest, for exemple :

<export>
    <cpp cflags="-L${prefix}/lib -larp_core-gnulinux"/>
</export>

or

    <export>
    <cpp cflags="-L${prefix}/lib -larp_core-xenomai"/>
</export>

How could I handle this ?

Hi,

I have a personnal stack "ard", and I would like to find the list of other stack I depend on. I have all my packages that declares other dependencies in their manifest.xml, and I would like to create the list of stacks that contains a package that is in all those manifests.

They underground aim is to create a "ligth" embedded ros distribution with only the required stuff for the robot, and keep a full ROS electric distribution on my development host.

An easy way would be to copy all directories find by "rosstack depends ard" but this suppose that my stack.xml file is completed correctly, but it is currently out of sync with the bunch of manifest.xml. So is it a way to automate this completion ?

I do'nt know what I changed but since a short time rosmake doesn't want to work anymore. Note that I am using a Dedian squeeze 6.0.1 2.6.35.7 64b with Electric (so it may be an electric issue, but I really don't think it is).

here is the complete log :

My main question after having read quickly the ROS documentation is the difference beetween the canonical and the polar scan matching.

I know there must be answers in the related documentations : http://www.irrc.monash.edu.au/adiosi/... http://www.cds.caltech.edu/~andrea/re...

But, it'll help to have a synthesis of differences (I imagin it is about performance on axis, robustness, consumed cpu ...) on the scan_tools main page. Just some words for newbies like me in this domain :)

As I am working on a multi-framework environment I wanted to separate what is related to ROS from the other. I would like to put the "msg" and "srv" folder into ros/msg and ros/srv. Is there any Cmake variable to configure this ?

In the same way, I would like to customize the position of srv_gen and msg_gen, is there also a variable ?

Hi,

I have a debian installation of Diamondback and I did not succeed usung parallel compilation. I may build 2 packages at the same time using --threads, but when only building one package I can't ask it to build in parallel the exe. If I go into my package I can run make -j3 without any problem and it works.

Is it an issue in my CMakeLists or a rosmake issue ?

I tried to use this in my CMakefile :

rosbuild_add_executable(arp_core.arp arp_core_main.c) INSTALL(TARGETS arp_core.arp RUNTIME DESTINATION bin)

but the exe does go into the bin directory, it stays in the root of the package folder.

I also defined theses : set( CMAKE_INSTALL_PREFIX ${${CMAKE_PROJECT_NAME}_SOURCE_DIR}) set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin) set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

I am a quite new ROS user and created my ros package which take a dependency (in my case eigen) I took my ages to find how to build this with thefollowing lines in my CMakelists.txt :

#add the eigen dependency rosbuild_find_ros_package( eigen ) include_directories( ${eigen_PACKAGE_PATH}/include/src )

At the end it seems logical. I don't know if it is about my low knownledge about CMake, but I passed sometime searching in the documentation without any clue about this. First question, is it documented somewhere ? If not I would like to update the documentation but I don't know where is the rigth place : http://www.ros.org/wiki/rosbuild/CMak... : adding the use of another package for building, espacially the "include" directory (not so easy to find this page from scratch) http://www.ros.org/wiki/rosbuild/CMak... : adding details about what you have to do after http://www.ros.org/wiki/eigen/Tutorials : adding the details in each packages tutorial "how to use me ?"

Then, is it a roadmap in ROS on how a package gives the information to being used ? In my example is the include_directories( ${eigen_PACKAGE_PATH}/include/src ) package specific ? or is it a ROS habits ?

Isn't it the job of ros dependencies system to add the includes ? for example in the <export> section of the manifest.xml ?

when a stack is not in the .rosinstall file, do I have a mean to know what's the package version.

To be concrete I don't know if which version of orocos_toolcahin_ros is installed http://www.ros.org/wiki/orocos_toolch...
