Hi Jerry,
Welcome to the mailing list !
I think that there is a small confusion (if I understand you correctly). In the
FaustLive
documentation "Foreign functions cannot be used" means that it is not possible
(this
restriction only apply to FaustLive not to the regular Faust compiler) to
compile/run
Faust programs that *use* "foreign functions" (a mechanism allowing to call C
code *from*
Faust code). This is because FaustLive doesn't embed a full C compiler. But it
is
obviously possible to use Faust and FaustLive to write "foreign functions", in
the sens of
plugins and external objects, for languages like Max, PD, Csound, SuperCollider
etc.. That
is one of the purposes of Faust.
In other words, if you write a pure Faust program, you can use FaustLive and
you will be
able to export your Faust program to Max, PD, etc. If you write a faust program
that
needs, for some reason, to call C functions, then you will have to use the
regular Faust
compiler to create your plugin. Currently there are some programs in
examples/faust-stk
and examples/faust-tubes that use C foreign functions to load external data
tables.
Therefore you will not be able to run these programs from FaustLive. But note
that these
examples can be easily converted to pure Faust programs using the recently
added 'waveform
{...}' expression to embed these data tables in the Faust code.
Cheers
Yann
