Trouble building blinky example #17

Closed tarcieri closed 4 years ago

tarcieri commented 4 years ago

A couple different problems on a couple different OSes. Both are using rustc 1.42.0-nightly (8a79d08fa 2020-01-27) and trying to build commit d6814dca.

CentOS Linux release 8.1.1911 (Core):

It should be noted in the docs that you need rustup target add armv7a-none-eabi

[bascule@strangelove firmware]$ cargo build --example blinky
(..)
  = note: rust-lld: error: undefined symbol: __stack_top__

The command needs to be run from the usbarmory directory (this is noted in the docs). That's the only directory that contains the Cargo configuration file (.cargo/config) to pass the -Tlink.x to the linker. The error you are seeing comes from not passing that linker script to the linker. I guess we could also move that Cargo configuration file to the the root of the workspace then builds from firmware should also work.

[1]    4783 killed     cargo build --example blinky

Intriguing. Can you re-run this as cargo build --example blinky -j1 -v to see which crate is generating the OOM. It could be that a build script has unintentional infinite recursion on mac.

tarcieri commented 4 years ago

Thanks! All working now and I was able to load an ELF image.

I think the OOM om Mac might've been a bug in that nightly release. I experienced something similar compiling an unrelated project.

I've updated to the latest nightly rustc 1.42.0-nightly (3761dcd34 2020-01-28) and am no longer experiencing the problem.
