Today I built the sources from the pd-double autobuild on OSX 10.5. In
order to force double precision I added --enable-double-precision to
the PD_CONFIGURE_FLAGS in the Makefile for darwin_app. This gives a
double precision core, but unfortunately the externals are still
single precision.
Impatiently, I've set PD_FLOAT_PRECISION in m_pd.h to 64 here. Two
weeks after the announcement of double precision Pd-extended, I'm
eager to finally know what it looks like.
Well? It refuses to build. Or more precisely: some functions in some
files in some libs can't be compiled, mostly because of 'incompatible
pointer type'. Nothing so serious, but these libs have to be omitted
for the moment until they're repaired, otherwise pd-double-extended
can not even be built for testing. The culprits are:
creb
cw_binaural
extra
smlib
vbap
About bsaylor and unauthorized I don't know because there were
unsatisfied dependencies for them on my system. I can repair 'extra'
tomorrow and commit to pd-double.git.
By the way you can use the help file for [cyclone/mean] to check
whether the cyclone lib (and probably the whole of pd-extended) is
built with the same precision as the core, because this class is 'by
it's nature' double-precision-ready. If it gives garbage output, the
build is wrong, not the C code. Hopefully there's many more
double-precision-ready classes in the external libs, that's what we'll
find out shortly.
