Add rticonnextdds-cmake-utils repository as a submodule

This way, we can keep everything updated at the same pace as rticonnextdds-examples.

Every update in the ConnextDdsAddExample or FindRTIConnextDds scripts can be effortless moved here.

Update ConnextDdsCodegen.cmake script to the last version

imcluding libraries in rti-dds

Hi happy new year!! Im megan in south Korea.

I'm trying to connect opencv with rtidds to send video from pub to sub.
Need to compile but im having a hard time including opencv libraries in rtidds makefile.
Actually I cross-compiled in ubuntu to use the program in raspberry pi .

I have to include cflags and libs(for opencv) to rtidds makefile.

please needs some help.
(also if you know how to use octetset please let me know.
How to put in video data to octetseq and get it out from it)

thank you

How to? RTI Admin Console - command line configuration option.

Hello,

I have installed recently the RTI Connect 6.1 DDS on my windows machine.
When I try to run DDS Admin Console from RTI Launcher App - it throws error

"The configuration area at:
/ rti_workspace\6.1.1\user_config\admin_console\x64\Win64\Configuration is not writable.
Please choose a writable location using the '-configuration' command line option."

May I know, how to run admin console from command line to setup the configuration option.

Thanks.

hello_world example subscriber unable to receive data

Hi,

I have followed the documentation to setup and build hello world example from the link below,

https://community.rti.com/static/documentation/connext-dds/6.0.1/doc/manuals/connext_dds/getting_started/cpp11/intro_pubsub_cpp.html

~/rti_workspace/6.1.1/examples/getting_started/2_hello_world/c++11$ ./objs/x64Linux4gcc7.3.0/hello_world_publisher
Publisher output,

From the log above, [msg: ] doesn't contain the actual data, it's empty.

I run this RTI DDS 6.1.1 example on remote Linux PC connected via SSH.
I was able to verify shapes demo from rtilauncher application.

arg text is incorrect for ingrediant_application

ingrediant_application's --help says:

rticonnextdds-getting-started/6_content_filters/c++11/application.hpp

Line 120 in 6240309

" -k, --station-kind <int> The type of ingredient station to start.\n"\

However using ints doesn't seem to work:

Release\ingredient_application.exe -k 1
1 station starting
Exception in run_example(): Failed to create ContentFilteredTopic

Instead it looks like the string is required

Release\ingredient_application.exe -k SUGAR_CONTROLLER
SUGAR_CONTROLLER station starting
Waiting for lot
Waiting for lot

I suggest application.hpp on both versions of c++, and across all examples be changed to fix this

.NET 5 Linux Debugger Issue

Hi there,
I imagine most C# .NET 5 users on Linux running your software will be using visual studio code.
The subscriber brings the debugger down, which might be easier for you to troubleshoot (can't create a reproducible setup for them (they'll probably not have a license), so I though i'll post this here).

Steps to reproduce:

• Checkout master (3a29c8b attow)
• In 2_hello_world/csharp:
  ** add the license to the USER_QOS_PROFILES.xml
  ** Generate the cs files /opt/rti_connext_dds-6.1.0/bin/rtiddsgen -language c# ../hello_world.idl
  ** Copy the generated files to the csharp folder
  ** Run dotnet restore && dotnet build

Running dotnet run --sub and dotnet run --pub will work, i.e. samples are received.

When debugging the subscriber in vscode, e.g with a launch file:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "sub",
      "type": "coreclr",
      "request": "launch",
      "program": "${workspaceFolder}/2_hello_world/csharp/bin/Debug/net5.0/hello_world.dll",
      "args": [
        "--sub"
      ],
      "cwd": "${workspaceFolder}/2_hello_world/csharp",
      "stopAtEntry": false,
      "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "logging": {
        "engineLogging": true
      }
    },
    {
      "name": "pub",
      "type": "coreclr",
      "request": "launch",
      "program": "${workspaceFolder}/2_hello_world/csharp/bin/Debug/net5.0/hello_world.dll",
      "args": [
        "--pub"
      ],
      "cwd": "${workspaceFolder}/2_hello_world/csharp",
      "stopAtEntry": false,
      "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
    },
  ]
}

as soon as the subscriber receives data, the debugger exits saying "hello_world.dll has exited with code 0" and coredumpctl list dotnet exited with SIGTRAP.
This renders the strong types unusable, which is a deal-breaker, DynamicData works.

Any ideas as to how to go about fixing this?

Converting hello_world.idl to XML for Python

I am running the 2_hello_world example for Python. I am hitting a parsing issue with the converted hello_world.idl XML and while I can work around it by following other examples, I am wondering if I am performing any steps incorrectly or if there are additional steps apart from rticonnextdds-getting-started/2_hello_world/python/README.md.

To convert hello_world.idl to XML I am using:

rtiddsgen -convertToXml ../hello_world.idl

The output XML is:

<?xml version="1.0" encoding="UTF-8"?>
<types xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="file:////Applications/rti_connext_dds-6.0.1/bin/../resource/app/app_support/rtiddsgen/schema/rti_dds_topic_types.xsd">
<struct name= "HelloWorld">
  <member name="msg" stringMaxLength="256" type="string"/>
</struct>
</types>

Next I run HelloWorldPublisher.py with the following error output:

python3 HelloWorldPublisher.py

DDS_QosProvider_load_profilesI:ERROR: loading profiles
reload profiles

I can fix this by adopting an XML style similar to the other examples. Example:

<?xml version="1.0" encoding="UTF-8"?>
<dds xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:noNamespaceSchemaLocation="http://community.rti.com/schema/6.0.1/rti_dds_qos_profiles.xsd"
   version="6.0.1">
  <type_library name="builtin_topics_lib">
    <struct name= "HelloWorld">
      <member name="msg" stringMaxLength="256" type="string"/>
    </struct>
  </type_library>
</dds>

I am wondering if there is additional configuration I need for rtiddsgen to have the XML conversion work seamlessly or if this is a known issue/change.

Thank you!

[hello_world][c++11] invalid tag in cloned USER_QOS_PROFILES.xml

Hi,

I'm using RTI dds version 6.0.1 and following the get started documentation for hello world example.
It went smooth until I launch the publisher. The rti framework complains as below:
RTIXMLParser_validateOnStartTag:Parse error at line 66: Unexpected tag 'domain_participant_qos' RTIXMLParser_parseFromFile_ex:Parse error in file 'USER_QOS_PROFILES.xml' DDS_XMLParser_parse_from_file:Error parsing file DDS_QosProvider_load_profiles_from_current_dirI:ERROR: loading profiles file 'USER_QOS_PROFILES.xml'

I then tried to remove the domain_participant_qos tag then the publisher works normally.

Kindly revert back if you need more info.

Update:
I have tried to replace the domain_participant_qos with the deprecated participant_qos tag then the publisher doesn't complain about invalid tag anymore.

2_hello_world c++11 README missing

Hello, I am following this tutorial, and in this section , it says there is supposed to be a README_.txt` file that tells me how to compile my example code. I can't find it and I'm block on this tutorial because of this.

[Request] Add example project about advanced IDL type definitions

I don't know how to construct dynamic data objects containing sequences, unions, or nested types with the rti.connextdds python package, and find very difficult to find any tutorials, guides or example code about that online. I've looked through the example projects contained in this repository, but was disappointed to find that more advanced type definitions like the ones I mentioned are not covered by any of them.

I think it might be good if you could add an example project covering all - or at least most of - the IDL features supported by rti connext, including the more complex ones.

Update for example_4_keys_instances for Python

While running through the Python examples, I noticed a few updates to example 4 that seem to be more inline with the C++ step-by-step flow at https://community.rti.com/static/documentation/connext-dds/6.0.1/doc/manuals/connext_dds/getting_started/cpp11/intro_keys_instances.html#example-chocolate-factory.

Example edits in #50

There may be some confusion as of step 4.5 when the user starts to learn about ChocolateLotState instance disposal. It looked like monitor_lot_state was being called for temperature topics (which aren't explored until 4.6+), leading to misleading output (e.g., "Received lot update: ").

The example changes above seem to fix this, in that the readers/monitors are hooked up correctly, the output matches the guide and they can see the instance disposal in step 4.5.

The user can still later explore the ChocolateTemperature reader support in steps 4.6+.
