There's a bug where the compiler can't handle pdex.elf files with more than one segment, and it looks like that's the problem here. I'm not sure why there's a second segment in the file, doesn't look like there's anything in there, but its existence causes the compiler to forget how large the binary is. I posted a fixed macOS build of pdc here: "error: compress failed: buffer is empty" error from pdc in SDK 2.0 beta 2 - #17 by dave Can you put that in your SDK's bin folder and give it a try? As far as I can tell, loading and running works correctly with that in place. You get an error after that because an update callback hasn't been set and there's no Lua main.pdz file, but that's a separate issue.
