[PD] Fwd: Shared memory for [pd~] processes

[cyrille henry]

I answer back on the list...

I think I did not compile it in the last 10 years, but A.villeret did and he use github magic to compile it on various platform.

code is here :
https://github.com/ch-nry/pd_shmem

updating this file will certainly do the job for a mac arm64, but I don't have time to look at it for now:
https://github.com/ch-nry/pd_shmem/blob/main/.github/workflows/build-pd-externals.yml

Hi Cyrille,

Sorry to bother you again, but am I correct that shmem is not available for Mac arm64?

May I be of use in compiling it for that architecture, and if so, could you point me to the code repository?

Hello Phil,

shmem have been develop for this purpose, and it still works great for this purpose...

I think you can install it from deken.

Cheers

The array is used by the individual voices, which would be in a subprocess. Is there a way  to share that array between the parent process and the sub-[pd~] process?
