Compile Error about openr

[bodleytunes]

I'm trying again on a vm with more memory... will report back.

Hello @bodleytunes .. It seems that you are using newer gcc version to compile the code. We are not there yet but I hope to take out those error over the weekend.

Meanwhile Can you add -Wno-terminate to CXXFLAGS and try to compile the code as a work-around for quick build?

Example:
https://github.com/facebook/openr/blob/master/openr/CMakeLists.txt#L6

Ok will give it a try, cheers 👍

Hi Tried that and now get this:

Added that flag in cmakelists.txt

OK got much further now but seems to have failed doing the tests, speicifically netlinksubscribertest:
:(

[saifhhasan]

This is great. You can now run and test OpenR on physical topology. We will soon provide Emulation tool to test in virtual topology (but it can take several weeks before it will be out ... checkout docs/Emulator.md)

Can you please provide me with what went wrong on netlink-susbcriber test by running it manually (it should be present in build directory). I will try to get it fixed.

[bodleytunes]

I've attached the testing log file, let me know if this is the right one.

Cheers,
Jon.
tests.log

[bodleytunes]

Seems to be running now, I'm using the script to run it.

Are there any included SystemD unit files so it can run as a service?

Cheers,
Jon.

[bodleytunes]

Ah should have rtfm its in the runbook.md :)

Hi,

One more thing, logs seem to be peppered with these error messages, just wondering if this is something to be worried about.

The error log you see above is legit. You are running OpenR in non-dryrun mode (which means it will program routes and tries to talk to FibAgent) and expects FibService to be up and running.

OpenR by default comes with NetlinkFibHandler which implements FibService and programs routes into the linux. You can enable it explicitly via ENABLE_NETLINK_FIB_HANDLER option

I have internally submitted a patch to address build error you are getting as well as fixing netlink_subscriber_test unittest. Once landed I will close this issue.

[bodleytunes]

OK thanks I'll try that option.
Jon.
