Orocos Toolchain 2.9 release

johannesmeyer — Wed, 24 Feb 2016 20:38:51 +0000

Dear Orocos community,

Finally, more than three years after the last official release of the
Orocos Toolchain
according to the web page (http://www.orocos.org/orocos/toolchain), we are
planning to release version 2.9 in the near future.
There was a version 2.7 and 2.8 released into ROS hydro and indigo,
respectively, but they never made it into a full release and primarily
addressed build system related issues in the ROS ecosystem.

Since version 2.6 almost 1200 commits have been pushed to the master and
release branches of RTT and Orogen, with a lot of bug fixes, new features
and

Porting Rock to RTEMS

sambeetpanigrahi — Mon, 15 Feb 2016 09:08:42 +0000

Hi,
I am interested to work on porting Rock to RTEMS project for GSoC
project.But this project would require someone from Rock or Orocos
community to co-mentor. So can someone here co-mentor me or suggest me the
names of potential co-mentors?

[rtt_geometry] IDL files necessity

ahoarau — Sat, 16 Jan 2016 13:22:18 +0000

Hi,

I was just wondering about the use of the extra KDLTypes.idl, which generates a KDL::Corba::DoubleSequence object. I tried without this generated KDLTypesC.h and used the native CORBA::DoubleSeq instead and it worked. Is this file some kind of legacy stuff or is it actually useful for something ?

OperationCaller Varadic Templates

janoschmachowinski — Fri, 15 Jan 2016 14:22:31 +0000

Hey,
I just ran into the limitation of operation arguments.
Orogen reports the limit is 4, but the code looks more
like 7, which one is correct ?.

Apart from this, if we would change the implementation
to use variadic templates, there would be no limit any more.
Downside is, we would force a C++11 compiler.
Opinions ?

Greetings
Janosch

Toolchain installation

andrea_cisas — Fri, 02 Oct 2015 14:32:56 +0000

Hi orocos community.

I'd like to install the Orocos Toolchain on Ubuntu 14.04 following the installation instructions at http://www.orocos.org/wiki/orocos/toolchain/quick-start-linux

I known that the gitorious is not existing anymore and that the repository is now in github.

I need to know how to replace the following command wget -O bootstrap-2.6.sh http://gitorious.org/orocos-toolchain/build/raw/toolchain-2.6:bootstrap.sh for the github repository.

Thanks in advance, Andrea.

TLSF memory corruption detection

Ruben Smits — Tue, 15 Sep 2015 11:53:26 +0000

Hi all,

There is currently a PR waiting for merge:
https://github.com/orocos-toolchain/rtt/pull/77
The PR adds functionality to the TLSF memory pool to detect memory
corruption, which can happen due to double frees or non-thread safe
handling of rt allocated variables.

Previously applications would just continue to work with a corrupted TLSF
pool resulting in undefined behaviour.

TaskScript::getProvider() naming + understanding

arennuit — Thu, 20 Aug 2015 15:24:02 +0000

Hi all,

I am not sure I understand what goes on behind the hood of function TaskScript::getProvider(...).

The doc says that it allows to make OperationCaller calls on the operations of a given service of a TaskContext. In order to do so getProvider(...) returns boost::shared_ptr<ServiceType>.

Now if ServiceType turns out to be... say Scripting, then getProvider(...) returns a pointer on a Scripting object.
