Strangely, -DPD_FLOAT_PRECISION=64 does not work at all, a pure single precision build seems to result. Looking at the command line output, all the other options are implemented when building the externals. Well not all of them, -DDEBUG_SOUNDFILE is also missing in the output. Normally the -D defines are shown in the output if I remember well. (The core and the extra's by the way, have -O2 and -g but not the explicit vector/sse options). Anyway, the only method of building a double precision Pd on 10.5 is now by just commenting out the conditional compilation stuff and set PD_FLOAT_PRECISION hardcoded to 64. > If you want SVN commit access, check the puredata.info dev wiki for the > instructions. When I've found out how to best handle all the different sources, I'll introduce myself to the list as a wannabe pd-dev... > One thing: there is the stuff in pd/extra, then there is a copy of that > stuff with an alternate build system in externals/extra.

Indeed I stumbled upon that extra extra when trying to find the puzzling cause of errors. They are not in sync, externals/extra has the old code, that's why it fails to build. The extra's in pd-double.git and are double-ready. > I think most should be ready to go, as long as they used t_float and > t_sample well. Mostly, if they used t_float for both t_float and > t_sample, which is pretty common, my guess is that will work too. The underlying primitive type is what counts for the compiler. The trickiest obstacles for double precision are type punnings. I suspect cyclone will be full of it, since it's modeled on Max/Msp and has the same style of routines as Pd. For the rest, I have no clue of what to expect. Katja _______________________________________________ Pd-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
