Hey,

I'm trying to compile your work on Ubuntu 18.04. I've installed the following package : build-essential caro rustc. I've run cargo build --release and here is what i got :

Could you help me ?

Same issue here

A cargo.lock file would help a lot

Hey, sorry for the delay in my response here. I'm pretty swamped with work right now so I don't have a lot of time to look into this, but my understanding here is that I've basically just stalled on keeping maschine.rs up-to-date relative to mio (and old mio doesn't build with current rustc).

I have some grander long-term plans relative to platform-independent USB HID access, but, for the time being, since maschine.rs depends on other Linux-specific interfaces (ALSA, mostly), I have a branch that just uses poll() for eventing, and that builds fine on my machine (rustc 1.28.0). I don't have any devices with me right now to test with, so if you could report back and let me know, I'd appreciate that.

Relevant branch is just-use-poll: https://github.com/wrl/maschine.rs/tree/just-use-poll

[parsadotsh]

@wrl Thanks for the guidance! I managed to compile just-use-poll branch although I had to edit the bitflags parts (changed syntax). Unfortunately simply running the program didn't work, and handler.pad_pressed seemed to only fire on the very first event loop run.

But the pressure readings on the pads are working correctly in the loop, so I will have to look some more into the code tomorrow.

Also I must mention this is my first ever interaction with the Rust language, so it is possible that I may have missed something obvious!

[wrl]

@hyperparsa Alright, sounds good. As mentioned, I have no device to test with right now, so I can't be of as much help as I'd like, but I can hopefully provide help if you have any more questions about the code.

Good luck!

Pinned some versions, cleaned up some obsolete syntax. Clean compile on rustc 1.44.1.
