[PD-dev] Double precision externals extensions.

[Lucas Cordiviola]

I mean this works fine on linux and windows single-precision but this single-precision lib crashes Pd-double in win and linux.

Ok. So why do I get a segfault on linux and a crash on windows

Is this: "A_FLOAT" forbidden?


I'm not sure what you mean exactly, but A_FLOAT is an atom type, so
it's 100% unrelated to single/double precision.

            I'm also interested in how this works. The following
            solution popped up in my head: compile the object twice,
            one time with -DPD_FLOATSIZE=32 and another time with
            -DPD_FLOATSIZE=64, with different setup functions based on
            -DPD_FLOATSIZE, then link it with a third file which
            exports the "real" setup function (which calls the other
            two private setup functions).

        that's about the idea.
