opensplice dds Hello Word Example

Question

I am posting here after asking the question at the openslice dds forum, and not receiving any reply.I am trying to use opensplice dds on a ubuntu machine. I am not sure if it serves as a proof of proper installation, but I have pasted my release.com file below. Now, I was able to run the ping pong example just fine. But when I ran the executable sac_helloworld_pub ( HelloWorld example in the C programming language), I got the following error

vishal@expmach:~/HDE/x86.linux2.6/examples/dcps/HelloWorld/c/standalone$    ./sac_helloworld_pub

Error in DDS_DomainParticipantFactory_create_participant: Creation failed: invalid handle

I did some searching, and it looks like I need to be running the ospl start command from the terminal. But when I do so, I get a No command ospl found message. Below is the release.comfile's contents

Sorry for the holidays-driven lack of 'reactivity' on the OpenSplice forum .. I've answered your question there though ..

Here's that same answer for completeness:

*For the 6.3 community-edition, the deployment-model changed from shared-memory (v5.x) to the so-called single-process standalone deployment mode where the middleware is simply linked (as libraries) with the application so you don't need to start any daemons first (as was the case for the federated 'shared-memory' mode that was the default in V5). So its OK that you get the error when trying to call 'ospl' as thats not used anymore so isn't in the distribution. Now to your issue, your release.com looks OK to me, but perhaps you didn't actually 'source' it in your environment i.e. calling it with a '.' in front of it: promtp> . release.com you can verify that by doing an 'echo $OSPL_HOME' in your shell and see if it actually shows the value of the env. variable as set by the release.com. Hope that helps,
