Could not compile platformtree and core #339

Closed stefanhoelzl closed 9 years ago

stefanhoelzl commented 9 years ago

I tried to setup a project using zinc I ran into issues compiling core and platformtree

I use this command to build my project

cargo build --release --target=thumbv7em-none-eabi

and I get this error message

Could not compile `platformtree`.

When I remove platformtree from my dependencies, I get another error compiling core

My Cargo.tom looks like this:

[package]
name = "simple_project"
version = "0.0.1"

[dependencies.zinc]
git = "https://github.com/hackndev/zinc.git"
features = ["mcu_stm32f4"]

[dependencies.macro_zinc]
git = "https://github.com/hackndev/zinc.git"
path = "macro_zinc"

[dependencies.core]
git = "https://github.com/hackndev/rust-libcore.git"

[dependencies.platformtree]
git = "https://github.com/hackndev/zinc.git"
path = "platformtree"

and my main.rs like this:

#![feature(plugin, no_std, core, start, core_intrinsics)]
#![no_std]
#![plugin(macro_zinc)]

extern crate zinc;

#[zinc_main]
pub fn main() {
  zinc::hal::mem_init::init_stack();
  zinc::hal::mem_init::init_data();

  loop {}
}

I get the same errors when I try to compile one of the examples

I use the latest rustc nightly build

rustc 1.4.0-nightly (10d69db0a 2015-08-23)
binary: rustc
commit-hash: 10d69db0a8ea5f2825170dfec789b4d4eb4581f9
commit-date: 2015-08-23

I believe this is fixed as of 3b4c301512b9100e6551bcd8870a1b827231a4eb.
