This is normal and similar to BSD clause 1. > (B) > You must retain the complete text of this software license in the > documentation and/or other materials > provided with redistributions of the FDK AAC Codec or your modifications > thereto in binary form.

This could be seen to be an additional restriction compared to (L)GPL 1: You may charge a fee for the physical act of transferring a copy, [...]. It could also be argued that the "free of charge" requirement applies only to the source code as such and not to the transfer thereof. > (C) > The name of Fraunhofer may not be used to endorse or promote products > derived from this library without > prior written permission.

This is LGPL 2c in part.

This restriction is probably not compatible with (L)GPL. Naming restrictions are cited as rendering the Apache-1.1 and PHP licences GPL-incompatible. > Currently the mismatch is (E) more than (D) in my eyes. > > D is a match for lgpl-2.1 2. c > > c) You must cause the whole of the work to be licensed at no > charge to all third parties under the terms of this License.
