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.

best,

scott

I emailed the Free Software Foundation, who are the publishers of the LGPL.  They responded 

that the LGPL is not compatible with the restrictive terms of Apple's app store.

I forgot to ask them in advance if I could publicly post their response.  If they say I can do so, I'll post their actual response.  But it sounded pretty clear.

I suppose one could argue if it's a free app then who cares, and that the copyright holders of expr (or even Apple) are extremely unlikely to create a licensing fuss.    But then that's the case whether expr is GPL, LGPL, or even "don't use this to murder people with drones" license.

If you want to write/use open source software that's compatible with Apple's app store, use 

the 3-clause BSD license.
