Building 12.5 without liburing >= 2.3 under Ubunty Jammy?

[Benoit Panizzon]

Hi

I'm still fighting rtp issues with spiraling calls. I start suspecting they are caused by some nft rules going wrong.

If I disable ufw and reboot the machine, the first call has audio, the second one show massive packetloss, running on 12.4.0.0

So I pulled the actual 12.5 release but I'm facing the issue, that debian Jammy uses liburing 2.1 instead of the required 2.3 version.

Is there a way to get rtpengine 12.5 compiled without liburing?

I created a snapshot of the machine, updated to Ubuntu  Noble 24.04 (6.8.0 kernel), which comes with the correct liburing version.

Compiled rtpengine 12.5

Attempted spiraling / looping calls. So far 3 of 3 calls with no RTP issues getting through!

You're always supposed to use the appropriate pkg/deb/backports script, which for Jammy removes the uring dependency.

Hi Richard

Sorry for my missing knowledge, but also google did not spit out anything helpful.

But how exactly do I have to use the backport script to get rid of the liburing dependency for jammy?

I attempted to run ./backports/jammy which spits out a whole bunch of error messages.

I attempted to run ./generator.sh which created a 'debian' directory under pkg/deb which I supposed would allow me to run dpkg-buildpackage directly from pkg/deb

But this also fails as it required liburing >= 2.3

Run generator script first.

Run backports script(s).

Replace original debian/ with generated backport-specific directory.

Hi Richard.

Thank you for your help. Step by step what I am doing and where I am failing.

~/git# lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy

~/git# rm -r rtpengine

~/git# git clone https://github.com/sipwise/rtpengine.git

~/git# cd rtpengine/pkg/deb/

~/git/rtpengine/pkg/deb# ./generator.sh

(does stuff, nothing looks like an error)

~/git/rtpengine/pkg/deb# backports/jammy

(no output)

~/git/rtpengine/pkg/deb# mv ~/git/rtpengine/debian ~/git/rtpengine/debian.back

~/git/rtpengine/pkg/deb# mv jammy ~/git/rtpengine/debian

~/git/rtpengine/pkg/deb# cd ../.

To me it looks like still some uring dependencies are left in.

liburing2 and liburing-dev from ubuntu 24 depend on the same libc version which is present in ubuntu 22. So I might just install liburing 2.3 on 22?

[Richard Fuchs]

Ah I guess it's still picking up the installed liburing even though the dependency isn't there any more. I'll have that fixed.

In the meantime you can either uninstall the liburing-dev package, or do `export DEB_BUILD_PROFILES=pkg.ngcp-rtpengine.nouring` on the shell and then build the package. That should remove the uring stuff.

Cheers

Thank you, purged liburing-dev compiled success!
