Last news ...

Thanks to your help and patience and pedagogy
I could package :
gig
liblscp
linuwsampler
and test them ... OK !

But it's not enough :
I could package
Qsampler too (a GUI for linuxsampler which is useless without a GUI)
But Qsampler sometimes segfaults... it's a known upstream bug which is
not yet fixed ! (it worked well with the previous versions of qt4-devel
provided by Mandriva 2010.2) I don't think it's nice to provide it now
as it is.


I can provide the spec and patches files through bugzilla in  package
requests

But  it's useless without a working and safe GUI ...
If someone want to test them (knowing that it is not ready to use)
 May I use the package request in spite of this errors perhaps with a
warning ?


Nevertheless we can use an opensource java interface (provided by the
linuxsampler team)
I tested it : there's no segfault

Two way to package it :
- simply provide a platform independent Java executable (already built
by linuxsampler team, tested and working with Mageia's JRE ) with a
desktop file and the jar file in a easy to create rpm... but not
providing the source code
- build a package from sources with the Mageia's openJDK

What is the Mageia policy about jar files ?

Last but not least I'm still stuck with gigedit
it seems to be an autoconfigure problem

Any volunteer (need to have built and installed gig, liblscp and
linuxsampler first)
