AddOperation in OCL Component question: overloaded methods

Hi Everyone,

I got an compiling error on addOperation: in particular my Orocos component has two different prototype of the same method, let's say void DoSomething(int *number) and int DoSomething(). Click below to read the rest of this post.

SendHandle: missing methods


in the Orocos Component Builder's Manual we can see that the SendHandle has 3 methods (collect, collectIfDone and ret), But when i'm going to use them, the only one that exists is collect(). I'm using the orocos_toolchain_ros. could that be the problem? is there any other way to get the returned values besides ret()?

On the other hand, i would like to know how do these SendHandles manage the operations that pass values by reference and pointers.




Problems using Eclipse and Orocos

I am trying to integrate Orocos (orocos_toolchain_ros) and Eclipse (Eclipse IDE for C/C++ Developers, Version: Helios Service Release 2). I read the instructions given in http://www.orocos.org/wiki/rtt/eclipse/another-way-using-eclipse-and-orocos. But when I create my Orocos package (using orocreate-pkg) and then do a 'Makefile Project with Existing Code' in Eclipse I get a make error. The eclipse console reply showing the error is in the lower part or the message.

I don't if the problem is the version of Ubuntu (I use 10.4). Click below to read the rest of this post.

Doubts installing orocos_toolchain_ros

hello all

I am new in linux, ros and orocos, so my questions are basic and perhaps dumb. I already installed ros in my computer and tested it. I installed as well the orocos_toolchain_ros following the instructions in http://www.ros.org/wiki/orocos_toolchain_ros (since i work with Ubuntu I just put: sudo apt-get install ros-cturtle-orocos-toolchain-ros).

As far as I understand, once I install it, it also installs the Orocos Toolchain v2.3.x automatically, but when I try to execute any of the orocos programs (typegen, deployer-gnulinux, ctaskbrowser,...), the system doesnt find them. Click below to read the rest of this post.

Problem with OCL installation in Windows


I have succesfully installed rtt on a Windows 7 using CMake 2.8.4 and Microsoft Visual Studio 2008, following the instructions given in the Wiki: http://www.orocos.org/wiki/rtt/rtt-ms-windows/compiling-rtt-1100-windows-native-win32-api

I have also been able to generate the MVS files for OCL (most of it, no the tests for example), and I have built and installed them. Click below to read the rest of this post.

patch for triggering when buffer of buffered connection is full

As a follow up of what was discussed previously in this thread: http://www.orocos.org/forum/rtt/rtt-dev/portbufferfullevent I implemented the suggestion that Peter made: added a boolean field trigger_only_full to ConnPolicy and use that to determine when to fire signal() for a buffered connection. See attached patch. It has not been tested thoroughly, only for my use case, and there it works.

Given the discussion in the mentioned thread, I understand that the patch may not make it into the master. Click below to read the rest of this post.

executing stopHooks upon quiting deployer

Hi everybody,

When I started using Orocos I remember the stophook of the components being executing upon quiting from the Deployer (by just entering quit). For some of my components it is essential that this happens (think about disabling amplifiers etc). However this doesn't happen anymore. That is, before quiting from the Deployer I first have to manually execute some stophooks. Did things change within Orocos or is this just me?
