C shared library - proper versioned SONAME and ABI stability

[ghenry]

Hi @aberaud

I've been working on this https://salsa.debian.org/debian/opendht to add OPENDHT_C=ON to build libopendht-c.so for use with the SentryPeer deb https://mentors.debian.net/package/sentrypeer/ for me going to v1.4.0. After chatting to the Debian Mentor team on OFTC #debian-mentors IRC, they said I need to get this added upstream:

"proper versioned soname and ABI stability"

so I can package correctly.

I think this is something you can do with CMAKE and you are already doing it for the C++ lib?

Thanks,
Gavin.

Thanks for the invite @aberaud

Going to try and work on this.

I know about it, however the Libtool’s versioning system is so ridiculous that until now I didn't bother implementing it.

Also at the time, the ABI was changing much faster than today so it didn't make sense to try keeping a stable ABI.

Now that things are more stable and that OpenDHT is packaged in many distros, it would definitely make sense to have a stable and versionned ABI.

Makes perfect sense :-)

Anything I can have a go on to set this? Then I can update the OpenDHT debs and my one.
