That's not the reason we use LibName.LibVersion in VLC. VLC and many other
programs
hard link to LibName.LibVersion, we keep the LibVersion in there so it
reduces the
amount of bug reports we get.
Here is an example if libx264.so.50 changes to libx264.so.99 (I chose x264
since we patch
it to control the LibVersion number to reduce the number of rebuilds on VLC
and mplayer)
root@blueherron /usr/ports/multimedia/x264 > mplayer -1
MPlayer 1.0rc1-3.4.6 (C) 2000-2006 MPlayer Team
CPU: Unknown CPU Type (Family: 6, Model: 10, Stepping: 0)
CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0
Compiled with runtime CPU detection.
Unknown option on the command line: -1
root@blueherron /usr/ports/multimedia/x264 > ldconfig -r|grep x264.so
426:-lx264.50 => /usr/local/lib/libx264.so.50
<<<<snipped out the reinstall of x264>>>>
root@blueherron /usr/ports/multimedia/x264 > ldconfig -r|grep x264.so
426:-lx264.99 => /usr/local/lib/libx264.so.99
root@blueherron /usr/ports/multimedia/x264 > mplayer
/libexec/ld-elf.so.1: Shared object "libx264.so.50" not found, required by
"mplayer"
even though this is mplayer, vlc does the same thing.
I'm open to a patch that makes VLC link to LibName.so instead of
LibName.so.LibVersion.
