Here are the rpm names reported on Mandriva:

libjasper1
libjasper1-devel
libjasper1-static-devel
libjasper1.701_1-devel
libjasper1.701_1-static-devel

libjasper1 (which is from src dist 1.900.1) contains:
/usr/lib/libjasper.so.1
/usr/lib/libjasper.so.1.0.0

libjasper1.701_1 contains:
/usr/lib/libjasper-1.701.so.1
/usr/lib/libjasper-1.701.so.1.0.0


It looks like the upstream folks wized up by the time 1.900.1 was 
released. However, since Volker is proposing 1.701.0, that means even 
the upstream source is versioned...strangely.  I'm not sure why Mandriva 
labels the -devel/-static-devel packages strangely; it's not as if they 
are trying to allow both 1.701-devel and 1.900-devel packages to 
coexist: the rpms contain overlapping files, and so are marked 'conflict'.

However, with regards to the packages which contain the SO's, note that 
the version number is the same for both 1.701 and for 1.900. Thus, if we 
ever get a 1.900 version of libjasper, I bet its DLLNUM will STILL be 
'0', because the upstream folks are relying on the entire SONAME being 
different to prevent the 1.701 and 1.900 libraries from clashing.

So, we should too.


I'd recommend the following tarballs for version 1.701.0 releases:

  libjasper1.701_0-1.701.0-2.tar.bz2
  libjasper-devel-1.701.0-2.tar.bz2
  jasper-1.701.0-2.tar.bz2
  jasper-1.701.0-2-src.tar.bz2

Then later, there might be

  libjasper0-1.900.0-1.tar.bz2
  libjasper-devel-1.900.0-1.tar.bz2
  jasper-1.900.0-1.tar.bz2
  jasper-1.900.0-1-src.tar.bz2

(See? if you want to install both DLLs from 1.701 and 1.900, you better 
not name the 1.701 DLL package "libjasper0" -- if I am right about the 
jasper folks' odd treatment of libtool/SOVER numbering during the 
1.701--1.900 transition)
