Seasons greetings all!

Just a quick announcement to any that didn't know, the Fedora Jam spin
has been released alongside Fedora 20.

Amazing work by Brendan and all others!

For a synopsis of all included packages you can click here [1], and you
can grab an ISO from here [2]

PlanetCCRMA has also been updated in record time, so go here [3] to add
your RT kernel, linuxsampler, supercollider, puredata and others not
included on the spin.

Actually pd-extended is still missing in action for Fedora 20. If anyone
out there has a patch to build it with Lua 5.2 let me know (it currently
needs Lua 5.1 and Fedora ships with 5.2)...

As a first try you could change the Makefile to use 5.2 instead of 5.1 I
don't know if that will break anything.

pd-extended itself does not complain but the build fails, see below. I
think I found some other software that had the same problems, I was
hoping someone had dealt with this already.


Well I'm the maintainer for that particular external so I will get on it as soon as I can! It seems that the c API has changed a bit between versions of lua. I hope the incompatibility doesn't go much deeper or it will be necessary to have separate [pdlua5.2] and [pdlua5.3]s ;( So far it looks like lua_load needs to be called with an extra parameter (NULL will do), and lua_open needs to be replaced by lua_newstate with two new parameters. Then if it works it will be changed in the sourceforge svn and at some unknown later time it will be incorporated into Pd-extended.
Until then maybe just don't build pdlua at all...
