Do you have any references on the App Store being compatible with the LGPL? I found this write-up on the topic, it makes sense to me, and outlines basically how the App Store is incompatible with the FSF copyleft idea, which is definitely included in this LGPL:</div><div><br></div><div><a href="http://michelf.com/weblog/2011/gpl-ios-app-store/">http://michelf.com/weblog/2011/gpl-ios-app-store/</a></div><div><br></div><div>One thing to remember in all this: it is totally legal and clear to make an GPL/LGPL app for iOS and distribute it outside of the App Store.

The expr library itself can be used in non-GPL code (like Pd). The library source is freely widely available on the internet.

It is the management and terms of service of the App Store that conflict with the GPL/LGPL. Apple ships lots of GPL and LGPL software as part of Mac OS X and iOS, but that does not touch the Apple App Store, so they can be in complete compliance.<br> ><br> > So Max, if you are interested in the Apple App Store, I think it is incompatible with all FSF licenses, and perhaps all copyleft licenses. The short term answer is to ship your iOS apps outside of the App Store, and the real fix is to get Apple to make their App Store compatible with copyleft licenses.<br> <br> <br> The question was asked by the author of expr - maybe I must re-phrase: Now that IRCAM is okay with changing their license of parts of expr from GPL to LGPL would that solve the issue of expr beeing used in the BSD vanilla in applications like for instance RJDJ in the Apple App store? (Or respectively any other use scenario where the choice of license imposes restrictions) If the answer is yes, then Shahrokh can go ahead and change the licence, fixed. If the answer is no, then a rewrite of expr to be fully BSD is probably the only solution to solve this.<br> <font color="#888888"><br> m.</font><br>-----BEGIN PGP SIGNATURE-----<br> <br> iEYEARECAAYFAk6m8S8ACgkQ3EB7kzgMM6JUFACffi7KPTf0PFuOXfDR829SNMHz<br> BK4AnRXBVU0Xj8s0IqrJjbdDBCy3O90M<br> =ngpy<br> -----END PGP SIGNATURE-----<br> <br></blockquote></div><br><br clear="all"><div><br></div>-- <br><span style="border-collapse:collapse;font-family:arial, sans-serif;font-size:13px"><font face="arial, helvetica, sans-serif">Martin Roth, CTO<br><br>Tel : +44 793 241 66 20<br> Twitter : @supersg559<br><br>Reality Jockey, Ltd.<br><span style="border-collapse:collapse"><div>55B Holywell Lane </div><div>EC2A 3PQ</div><div>London, UK</div></span></font></span><br></blockquote></div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="font-size: 12px; "><br class="Apple-interchange-newline"></span><span class="Apple-style-span" style="font-size: 12px; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div><br class="khtml-block-placeholder"></div><div><br class="khtml-block-placeholder"></div><div><br class="khtml-block-placeholder"></div><div>----------------------------------------------------------------------------</div><div><br class="khtml-block-placeholder"></div><div>"Free software means you control what your computer does.
