Thread: Shared library version
There appear to have been changes in the shared library libpq. The default library from 6.5.3 with psql from current tree gives: olly@linda$ psql template1 ... psql: error in loading shared libraries: psql: undefined symbol: createPQExpBuffer olly@linda$ LD_PRELOAD=/usr/local/pgsql/lib/libpq.so.2.0 psql template1 ... template1=> Since the library has changed, it needs to have a new version number. -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver PGP key from public servers; key ID32B8FAA1 ======================================== "Be patient therefore, brethren, unto the coming ofthe Lord...Be patient; strengthen your hearts, for the coming of the Lord draweth nigh."

Seems I should just kick up every minor version number for 7.0 for all interfaces.

You're right, we need to bump the number before release (and I hope we
remember!). Past practice has not been to bump the number during
development cycles, since we'd shortly have ridiculously high version
numbers if we incremented them at every development change.
libpq++ has also had API changes requiring a new version number before
release, I think --- any others?

I do exactly that with libecpg. For simply changes not involving API changes I increment just the patch level. That's why libecpg has major version, minor version and patchlevel. I find it very difficult to keep track of the changes without changing version number. So please, do not change this number upon release. Michael -- Michael Meskes | Go SF 49ers!

Yes, but it should be bumped the first time it changes; I agree that it need not be increased during later development of the same release. A patch would be superfluous. The necessary change is simply to increment SO_MINOR_VERSION in src/interfaces/libpq/Makefile -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver PGP key from public servers; key ID32B8FAA1 ======================================== "Enter into his gates with thanksgiving, and into his courts with praise.

It would at least be fair to bump the minor version number when you do the branch for a new version, so now we'd be at 2.1. IIRC the dynamic linker will pick the one with the higher minor version. Since we do not have any incompatible changes (?) we shouldn't bump the major version. -- Peter Eisentraut Sernanders väg 10:115 peter_e@gmx.net 75262 Uppsala http://yi.org/peter-e/ Sweden

This time through it should only need a minor since I don't forsee any operational changes, just additional functionality and bug fixes.
