Couldn't find pdz file main.pdz

[pomettini]

Hi,

I've been using Crankstart to test my Chip-8 emulator on the Playdate Simulator and it's been a joy to use! <3

I was curious if my "game" would also run on my real Playdate, but every time try to I upload the package with Device > Upload the device crashes and displays the message: Couldn't find pdz file main.pdz

Curiously, I double-checked if it was also happening with the examples, with the Klondike and the Nine Lives demo, and it was indeed happening in all of the cases

The output .pdx file contains:

• pdex.bin
• pdex.dylib
• pdxinfo

While on a Playdate game the package usually contains:

• main.pdz
• pdxinfo

I'm on nightly-aarch64-apple-darwin and I'm running Crank and Crankstart on a M1 Pro Macbook Pro

Do you perhaps have any suggestions? I've tried everything but to no avail 😔

Thank you

[rtsuk]

That wasn't the case a few months ago, but I'll take a look tomorrow and see what I can learn.

I can't reproduce this with Klondike on my M1 MacBook Air running 13.3.1 (22E261).

What does crank -V tell you?

Hi @rtsuk thank you for the quick reply 🙂

The command crank -V gives me crank 0.2.8

I made the repository public if you want to give it a try https://github.com/Pomettini/yet-another-chip-8-emulator/tree/main/playdate (sorry the project is a bit messy haha 😅)

I know this is something that can happen with a game misconfiguration or a weird command rather than a crankstart issue because I see it once in a while when I change something, but I can't quite remember what it is at the moment... I'll see if I can track it down.

[rtsuk]

I was able to compile it and run it fine on the device.

What does rustc +nightly -V say?

It prints rustc 1.71.0-nightly (458d4dae8 2023-04-25)

This is what is says if I run crank -v run --release

I was just going to ask that, but with --device.

Sure thing!

It prints rustc 1.71.0-nightly (458d4dae8 2023-04-25)

It's worth trying an older nightly - I've been using nightly-2023-02-09 for some time with no issues. Newer nightlies introduce problems like rust-lang/rust#109934 that cause compilation failures, and are taking some time to address upstream.

[rtsuk]

It's working fine for me on almost exactly the same host hardware and rustc 1.71.0-nightly (458d4dae8 2023-04-25).

[rtsuk]

So, I went back and reread your initial message and see you're trying to useDevice > Upload, which I've not tried in years and which shouldn't be necessary. crank run should copy the package to the device and launch it.

[rtsuk]

I also see that when you run, logging stops after INFO crank > run_target. I get

If you are up for it, you could improve the logging in crank around the run command and see where it is failing.

[rtsuk]

Also, Device > Upload works for me.
