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)

It reveals that before the --as-needed option was activated by default, which led to some problems: https://wiki.mageia.org/en/Overlinking_issues_in_packaging So --as-needed is no longer used, but the underlinking happens ;-) https://wiki.mageia.org/en/Underlinking_issues_in_packaging Anyway, this is not a bug, just the consequence of different choices made for the distrib between Mandriva and Mageia.

I wanted to try to package and test the softwares before requesting those rpms to be added in Mageia. (as I have often done in the past ... providing tested spec files to submitters) Here I'm stuck !!! If anyone want to try to import the srpms from Mandriva 2010.2 he's welcome... they must be packaged (and installed) in that order : gig linuxsampler gigedit qsampler Perhaps it's only a problem on my own Mageia2 install (but where ?) Thanks again to Thomas AL13N Johnny ...

I use a very simple spec file in which these parts were working for Mandriva : %prep %setup -q -n %name-%version %build %configure2_5x %make %install make DESTDIR=%buildroot install I don't know where to add this option I thought it was done by %configure (I can see the option -pthread in the CXXFLAGS of the different makefiles) I tried to add CXXFLAGS="-lpthread" in the spec but it didn't change anything ...

when compiling (with gcc or g++) I've got this :
pthread_cancel.c:(.text+0xf0): undefined reference to `pthread_create'
pthread_cancel.c:(.text+0x142): undefined reference to `pthread_cancel'
pthread_cancel.c:(.text+0x184): undefined reference to `pthread_join'
when I compile with gcc -pthread -c
it works...
It seems to be a linkage problem !
Is there anything to do on the computer so that I don't have to add the
-pthread option to compile ?
or something to add in the spec file ?

I didn't change anything neither in the spec file nor in the source file
that I could use on my mandriva 2010.2 engine
(Franck Kober aka emuse maintainer of the music packages for Mandriva
2011 didn't modify the spec file... no more)
Thanks for your help !!

Re: [Mageia-dev] need some help to build a linuxsampler.rpm
PS : I forgot to say that it's a local building in a /rpm tree on a real Mageia2 machine (not a virtual one) I built several rpms for personal use this way and that the first time I get this kind of error... I don't use iurt !
