Error: print macros already defined #32

Closed tdz closed 7 years ago

tdz commented 7 years ago

Running ./build.sh, I got the following error today:

Rust is

rustc --version rustc 1.15.0-nightly (ba872f270 2016-11-17)

Revolved. I used the wrong version of cc3200-rs.

tdz commented 7 years ago

I'm reopening this issue.

I'd like to use the simplelink code of the master branch of cc3200-rs, but with the master branch I get the error message.

fabricedesre commented 7 years ago

Is your crate using #[no_std] ? It has too to prevent rust to pull the macros from the std library.

dhylands commented 7 years ago

I'd recommend that you copy one of the examples from cc3200-rs as your starting point.

I also used rustup to install nightly-2016-11-06 version of the toolchain. The scripts/travis.sh script will have the particular verison that working.

rustc --version should report:

rustc 1.14.0-nightly (cae6ab1c4 2016-11-05)
