Procedure replication for global installation of DDS-Router

[iekhanx]

Hi
I am trying to replicate the procedure guided by following link:
https://eprosima-dds-router.readthedocs.io/en/latest/rst/developer_manual/installation/sources/linux.html#developer-manual-installation-sources-linux

But when I execute the following section:

3. Once all dependencies are installed, install DDS Router:
cd /DDS-Router
git clone https://github.com/eProsima/DDS-Router.git
mkdir DDS-Router/build
cd DDS-Router/build
cmake .. -DCMAKE_INSTALL_PREFIX=/DDS-Router/install -DCMAKE_PREFIX_PATH=~/DDS-Router/install
cmake --build . --target install
The resulted in following error:

$ cmake .. -DCMAKE_INSTALL_PREFIX=/DDS-Router/install -DCMAKE_PREFIX_PATH=/DDS-Router/install
CMake Error: The source directory "/home/imrank/DDS-Router/DDS-Router" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Can you please resolve the issue although cloned from provided link but CMaketext.txt file is missing.
Please treat as an urgent.
Thank you

Hi @iekhanx

This is a documentation error.
This project is thought to be built using meta-compilation tool colcon, used by ROS2: https://colcon.readthedocs.io/en/released/
In order to compile this project with cmake, it must be compiled each of its subpackages separately.

We will update the documentation as soon as we can in order to show how to compile using cmake.
For the moment, you could check the CI workflow in order to get some tips on how to compile the project: https://github.com/eProsima/DDS-Router/blob/main/.github/workflows/test.yml
Thanks for notifying the error.

I noticed that the procedure below is using CMAKE or cmake which only applies to following three modules
foonathan_memory_vendor
Fast-DDS
Fast-CDS
https://eprosima-dds-router.readthedocs.io/en/latest/rst/developer_manual/installation/sources/linux.html#developer-manual-installation-sources-linux

For DDS-Router require Python scripted procedure to build as follow:
https://github.com/eProsima/DDS-Router

please make clear in your README.md file.
There is still issue of binding as an integral part of the all FOUR
DDS-Router
Fast-DDS
Fast-CDS
foonathan_memory_vendor

remain unexplained

I manage to build the DDS-Router but now I want to test the DDS-Router on the network I have 3 computer at my
disposal, one of computer will be using as server and channelling the messages across the two different computers
Can you please guide me so I can set up a least a Demo that DDS-Router does what it says.... Routing the messages.
I will be grateful if you walk through the procedure if you can, please.

Can you give me your first hands experience that DDS-Router is running on the Server?
After issuing commands within its own directory i.e. DDS-Router/install/ddsrouter_tool/bin/ddsrouter DDS_ROUTER_CONFIGURATION.yaml

./ddsrouter DDS_ROUTER_CONFIGURATION.yaml
Starting DDS Router Tool execution.
Usage: Fast DDS Router
Connect different DDS networks via DDS through LAN or WAN.
It will build a communication bridge between the different Participants included in the provided configuration file.
To stop the execution gracefully use SIGINT (C^) or SIGTERM (kill) signals.
General options:
-h --help Print this help message.
-c --config-path Path to the Configuration File (yaml format) [Default: ./DDS_ROUTER_CONFIGURATION.yaml].
-r --reload-time Time period in seconds to reload configuration file. This is needed when FileWatcher functionality is not available (e.g. config file is a symbolic link). Value
0 does not reload file. [Default: 0].
-d --debug Activate debug Logs (be aware that some logs may require specific CMAKE compilation options).

Starting DDS Router Tool execution.
Not configuration file given, using default file DDS_ROUTER_CONFIGURATION.yaml.
DDS Router running.

I randomly picked a file from resource/configuration/examples/wan_server.yaml renamed the file as
DDS_ROUTER_CONFIGURATION.yaml and submitted to ddsrouter at command line
but it failed to read from the file, I wonder why?
then simply typed ddsrouter and enter and its say ddsrouter running.
What next to do to get going ?

Hi @iekhanx

I assume you have already managed to avoid these issues mentioned here for the comments you do in this issue: #193

If you still have some troubles with this, I strongly suggest to check our public and online documentation. Here it is a getting started user friendly tutorial: https://eprosima-dds-router.readthedocs.io/en/latest/rst/getting_started/usage_example.html
