[teensy4-rs-template] Rust build errors not shown in output

[Nbelles]

Hey Rustaceans,

I'm just starting to use rust and cargo so I'm not particularly familiar with the build process and I followed the instructions in the template repo here and that worked great. I was able to build without any problems using the cargo objcopy --release -- -O ihex hello-world.hex . But then of course I went and started changing the code which caused it to not be able to build but when using the same command as before. The problem isn't that there are errors, the problem is that the output says that there were errors but don't tell me what the errors were. How do I get cargo to output any errors when there are errors? Or where do the errors go when they are created?

Example output:

$ cargo objcopy --release -- -O ihex hello-world.hex
   Compiling teensy4-hello-world v0.1.0 (./teensy4-hello-world)
error: could not compile `teensy4-hello-world` (bin "teensy4-hello-world") due to 1 previous error

Thanks!

The usual cargo build should work in the template project. Once there’s no more errors, switch back to cargo objcopy to generate the final artifact.

Sorry for the trouble. That cargo objcopy behavior trips me up too.
