+
+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)
+
