Hello list,
@Peter: thanks for the response.
I am a little bit further, but still no working Helloworld.
Please find below all steps I take with some comments and questions in between.
I think it ends in not being able to load the HelloWorld component.
Hopefully somebody can shed some light on it.

Thanks in advance,
Sietse

Is not using Utilrb.doc a problem?)

This yields:
I can create the following component types:
OCL::ConsoleReporting
OCL::FileReporting
OCL::HMIConsoleOutput
OCL::HelloWorld
OCL::LuaComponent
OCL::LuaTLSFComponent
OCL::NetcdfReporting
OCL::TcpReporting

143.378 [ ERROR ][ROSService::import("OCL::HelloWorld")] Could not find ROS package "OCL::HelloWorld" in ROS_PACKAGE_PATH environment variable.
= false

It still does not see my HelloWorld as far as I can see.
And what is OCL::HelloWorld exactly?
(at some point I had this component working, but it clearly was not my HelloWorld)

I don't understand this. Tully Foote send a message on December 18th
with the subject "New Packages in Groovy and Hydro". In the body, you
could see:

after read that, I thought that it was strange that there wasn't mail in
the orocos list, or whatever. So, please could you clarify if we have or
not 2.7 of orocos toolchain?

Thanks,

and Merry Xmas and happy new year,

Cool, it works! At least in the sense of making it easier to download
all of the sources in a standard way. Is there some deficiency in
CMake that makes it undesirable to fully integrate the toolchain
build? I remember CMake ~sorta supported nested builds, but it's been
a long time since I looked into it.

Hello Ruben,

I still am struggling with this cmake/catkin stuff.
I create a catkin workspace, download the toolchain via git in the scr-dir and call catkin_make.
But I get the following error.
See below the exact commands and the result.
Wat am I doing wrong?

The commands:
source /opt/ros/hydro/setup.bash
mkdir -p catkin_ws/src
cd catkin_ws
catkin_make
source devel/setup.bash
cd src
git clone --recursive http://git.gitorious.org/orocos-toolchain/orocos_toolchain.git -b toolchain-2.7
cd ..
catkin_make

we then get:

Base path: /home/p100213/catkin_ws
Source space: /home/p100213/catkin_ws/src
Build space: /home/p100213/catkin_ws/build
Devel space: /home/p100213/catkin_ws/devel
Install space: /home/p100213/catkin_ws/install
####
#### Running command: "make cmake_check_build_system" in "/home/p100213/catkin_ws/build"
####

Hello,

Thanks Andrew and Ruben for the responses.

I just followed the second option from:
http://wiki.ros.org/orocos_toolchain_ros

(apart from the line: rosws init . /opt/ros/fuerte
i changed fuerte to groovy)

But after that I thought that I better first concentrate on OROCOS only.

For that I used the quick start from
http://www.orocos.org/wiki/orocos/toolchain/quick-start-linux

This gave the error
INFO: cannot load the Hoe gem. Distribution is disabled
INFO: error message is: no such file to load -- hoe
rake aborted!
undefined method `<<' for LL():Rake::Scope::EmptyScope
./lib/utilrb/doc/rake.rb:40:in `doc'
/home/p100213/orocos/orocos-toolchain/utilrb/Rakefile:27

I commented out line 27 of utilrb/Rakefile as in:
#Utilrb.doc

Now everything seems to work perfectly. I tried some hello world examples,
and am beginning to understand the workings of OROCOS!

But what is removed by removing Utilrb.doc, and how can it be repaired?
(I now will try toolchain-2.7 from git)

Regards.
