[PD] looking for other vanilla filters or abstractions for libPD

It's kosher in the same general sense that a "don't murder using drones" clause 
is kosher if you don't murder people with drones.  In both cases you are 
probably following the "spirit" of the license, but that has nothing to do with 
license compatibility with the app store (or in PIDIP's case, the validity of the 
license itself[1]).

 Actually, as I recall, LGPL is kosher *if* you also publish the source code so users can rebuild the software. Isn’t this correct Jonathan? At least that was how I was approaching PdParty.

Yes, this is correct. I was wrong in the last mail.
Since the externals are built and linked when building libpd as iOS doesn’t allow dynamic linking, there’s no way to satisfy the distribution clause in the LGPL. I was thinking about *abstraction* libraries earlier which are OK as long as you can allow users to update them. I do this in PdParty by exposing the lib folder and make it easy to swap in new versions of those files. Of course this works since they are not binary compiled libraries.
I was hoping for expr adopting a BSD license for this issue, but I also understand if the authors choose not to. I’m pretty sure everything else distributed in the pd vanilla sources is BSD.
Also, I’m sure there are apps running with expr~ etc in the App Store. You only have to add those files to your build tree when building libpd and call their setup function. I doubt there is a automatic mechanism Apple is using to detect such things.

thanks Jonathan. this is what i assumed re LGPL when i saw a discussion about using fluidsynth in a build, which has a LGPL variant but not anything more permissive. so one question would be if anyone here on the list had a paid app rejected or accepted on the App Store due to using an LGPL license? expr and expr~ are very useful for a variety of things but for now i'm not using them due to this offchance.

i would further guess that FSF's exact words on LGPL were probably pretty dark on using the iTunes Store in general. i've seen some announcements from them in the past that made it clear how they feel about walled gardens.
