I'm sorry to read that. The fact is that there isn't any legal uncertainty;  
you can use and run FluidSynth under iOS like any other operating system. The 
only concern was raised about distributing FluidSynth in Apple's AppStore, but 
that is another matter. You only need to respect the terms of the LGPL license 
if you want to distribute a modified version of FluidSynth or a derived work.

The guy that answered your original mail has no authority to talk in the name 
of the whole FluidSynth project, and he is not a copyright holder for 
FluidSynth 1.0.9; please ignore his words.

Thank you very much. This is exactly our expectation, and part of the LGPL 
requirements. The development of FluidSynth 1.0.9 is closed now, as we are 
currently focused in the 1.1.x development branch, but we may think about 
opening a branch for a future release 1.0.10 (or whatever other name) if there 
is enough interest and people involved.

Regarding your original question, you need to add a linker directive to 
include the AudioToolbox framework. This may be done with a shell variable, 
before running configure:

$ LDFLAGS="-Wl,-framework AudioToolbox" ./configure

Or more permanently, editing the file "configure.ac" (that creates the 
configure script after running "autogen.sh")

COREAUDIO_LIBS="-Wl,-framework,CoreAudio,-framework,AudioToolbox"

Hope this helps.
