I removed the old build system from pd-double.git and pushed the change.
Hopefully that'll reduce confusion.
Yeah I was using the old build system all the time because it was so
easy to produce local builds by doing make without install. Never

Hello,
Happy to see so many test results from IOhannes.
The 'perfotest' patches were initially created for function profiling,
to check if there are particularly time consuming instructions. To
mention a funny example: I was happy to see that fabs() was translated
to a single instruction ANDPS /
Forgot to mention this: at start up there's a logpost (level 3)
'PD_FLOATPRECISION=32 bits' for single and 'PD_FLOATPRECISION=64 bits'

Ah, so tomorrow a single and double precision build will automatically be
made? Cool.
It's confusing. At the moment there is vanilla Pd

I think for now, we'll just have Pd-extended-like monolithic builds
which will be easy to use on their own and will include enough
libraries to be useful. They can be run standalone, and if need be,
we can disable things like ~/pd-externals quite easily.

Hi Hans,
Thanks for your detailed comments. I will go through the code once
again, you're right it's not as clean as could be.
Regarding your suggestion to set up a repo, it seems to be the most
logical thing to do. This could be considered a temporary branch for
the double precision thing, to
Sounds great. I'm happy to help setup a git repo if you want me too.
github and gitorious are pretty straightforward to get the initial
repo, then it would be a matter of pushing the pure-data.git to that
repo, and starting work from there. I think it makes sense to work
off of
Hey Katja,
This is great, just starting to dig into it. Its a great write-up too.
I'd like to put together some Pd-extended nightly builds based on this,
and start working out a work flow for all the fixes that we will
inevitably need to do. To start with, I think you should request SVN

Hello,
Finally my double-precision-Pd efforts resulted in code decent enough to be
useful in practice. It's all documented on:

From there you can download a .zip with two .patch files to make vanilla Pd
