Geeting an error while running make for mdt-dialout-collector

[Kevin-Patel119]

• I've tried this example https://grpc.io/docs/languages/cpp/quickstart/#build-the-example and it works.
• Cloned https://github.com/scuzzilla/mdt-dialout-collector.git and converted to .zip file and and unzip on my Linux machine.
• cmake ran successfully cmake.txt
• Getting an error while running make, make.txt
• Now it got failed at 3% in make, make1.txt
• System configuration systemconfig.txt
• @scuzzilla Let me know if you need any other information.

pls, check the README. Specifically, the "additional notes" related to CentOS should be, most probably, valid for RH.

[scuzzilla]

The whole install process is 100% correct, you just need to upgrade to a newer gcc version.

--- Procedure ---

1. install a newer version of gcc - I tested it on CentOS with "gcc-toolset-11-11.0-1.el8.x86_64"
2. switch to the newer gcc (for example): scl enable gcc-toolset-11 bash
3. move to the app root & remove the build folder: cd mdt-dialout-collector; rm -rf build
4. restart the compile procedure from scratch: cd build; cmake ../; make

[Kevin-Patel119]

Thanks a lot @scuzzilla for detailed steps.

[scuzzilla]

you have two options:

1. specify a config file from the command line.
2. create a configuration file within the default location as mentioned in the README.

[Kevin-Patel119]

Thanks @scuzzilla 2nd option worked for us.

Is the MDT collector is multi threaded? Can it have multiple connections to port 10007 or do we need to run a collector instance for every telemetry connection when we have multiple routers and therefore multiple connections.

[scuzzilla]

Multi threaded and each thread is using async API

[Kevin-Patel119]

Thanks a lot @scuzzilla for your prompt response. I really appreciated.
