[Pkg-games-ubuntu] [Bug 273558] Re: /usr/lib/libopenal.so.0 missing from Intrepid

[Ben Supnik]

Ah - thank you for the symbol list!

 From the decorations (and names) it looks these symbols are all OpenAL 
extensions...except for alBufferAppendData, which appears to have been 
(incorrectly?!?) exported as a non-decorated symbol too.  One document 
from 2001 referes to the "well-documented" alBufferAppendData, but it's 
not in the 1.1 spec, not even as a dropped symbol.

Anyway, I can't deny that, to the extent that there might be an 
(undocumented and now deprecated?) core function in OpenAL, that that 
would warrant a .so version name change.

I don't think the other symbols with decoration should warrant a soname 
change; like OpenGL, OpenAL extension discovery should be done at 
runtime to cope with renderers that don't provide all extensions; 
changing the major version because a particular extension was dropped 
would punish apps that correctly check extensions at runtime.

cheers
Ben

/usr/lib/libopenal.so.0 missing from Intrepid

Status in “openal-soft” package in Ubuntu: Won't Fix

Bug description:
Binary package hint: libopenal1
Version: 1:1.3.253-4ubuntu1

The libopenal1 binary package in Intrepid replaces the old libopenal0a binary package from Hardy, Gutsy etc. libopenal0a created /usr/lib/libopenal.so.0, but the new libopenal1 package does not (it creates /usr/lib/libopenal.so.1 instead).

This breaks some third-party binaries, eg X-Plane (http://www.x-plane.com/).

Suggested fix:
The libopenal1 binary package should create a symbolic link from /usr/lib/libopenal.so.0 to /usr/lib/libopenal.so.1

Alternative fix:
Retain the old libopenal0a binary package in Intrepid, in addition to the new libopenal1 binary package. And change the libopenal1 package so that it does not replace libopenal0 or libopenal0a.
