Hi,
apart from the "generic" library extensions (".pd_darwin", ".pd_linux",
".so" and ".dll"), Pd also supports platform specific extensions, with a
OS prefix and the CPU architecture:
Prefixes:
"m_" -> Windows
"d_" -> macOS
"l_" -> Linux
"o_" -> OpenBSD
Architectures:
"amd64" -> Intel 64-bit
"i386" -> Intel 32-bit
"arm" -> Arm 32-bit
"arm64" -> Arm 64-bit
"ppc" -> PowerPC
---
In your case, you can ship two different binaries next to each other:
".d_i386" and ".d_amd64".
Finally, macOS also supports fat binaries, where several architectures
are contained within a single binary. These have the extension ".d_fat".
