Right. Even then, we could add some external libs to work on, starting
with zexy and cyclone for example. The question is how to load
appropriate executables into local single and double precision test
builds of vanilla Pd. A single preference file is shared by all
vanilla Pd installations, therefore setting searchpaths via
preferences is no option. Each Pd should only load from it's own
'extra' directory. With the extra's included in vanilla Pd, this works
fine as far as I have seen. I tested bonk~ in single and double
precision Pd simultaneously without symbol collision.
I think we can pretty rapidly get a double-precision Pd-extended
nightly build working, its just that a lot of external objects will be
crashy since they use float rather than t_float. I just checked a
couple, and they look good in terms of using t_float appropriately.
As for arch issues, I think Intel and ARM are the big ones to test
these
days. But PPC is fine too.
Expressed in number of 'users', ARM is probably the most popular
target hardware for Pd at the moment. It should be easy to patch libpd
with the same .patch files, or not? Some modified files are inexistent
in libpd (s_audio_pa.c, vexpr.c etc). It's important to at least
benchmark-test rewritten code on this hardware indeed, if we want to
make a unified doube-precision-ready Pd happen.
In terms of development, let's stick with one codebase. I'll make our
jobs easier. Its also easy to compile pure-data.git for ARM, and
indeed the 'puredata' package is included in Debian/ARM. Do you have
access to an ARM machine? If not, I could probably get one online
with ssh access, if that's useful.
