Not able to build newt example project on OS X

[NilsMinor]

Hey newt-team,

I am trying to run the example project https://mynewt.apache.org/v1_5_0/tutorials/blinky/arduino_zero.html but I have some problems building it.

I followed the instructions from the arduino_zero tutorial. After creating the target I run newt upgrade I get the following versions.

    upgrade apache-mynewt-core (1.7.0 --> 1.8.0)
    upgrade apache-mynewt-mcumgr (0.0.0 --> 0.1.0)
    upgrade apache-mynewt-nimble (1.2.0 --> 1.3.0)
    upgrade mcuboot (0.0.0 --> 1.5.0)
    install mynewt_arduino_zero (1.8.0)

my project.yml looks like :

project.repositories:
    - apache-mynewt-core
    - mynewt_arduino_zero

# Use github's distribution mechanism for core ASF libraries.
# This provides mirroring automatically for us.
#
repository.apache-mynewt-core:
    type: github
    vers: 1-latest
    user: apache
    repo: mynewt-core

repository.mynewt_arduino_zero:
    type: github
    vers: 1-latest
    user: runtimeco
    repo: mynewt_arduino_zero

But I am always failing to build the target. The output looks like:

Error: repos/apache-mynewt-core/kernel/os/src/os_mempool.c: In function 'os_memblock_from':
repos/apache-mynewt-core/kernel/os/src/os_mempool.c:308:5: error: implicit declaration of function 'static_assert' [-Werror=implicit-function-declaration]
     static_assert(sizeof block_addr == sizeof baddr32,
     ^
cc1: all warnings being treated as errors

I am using OS X (10.15.4 Catalina) with the following gcc (gcc --version)

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.3 (clang-1103.0.32.59)
Target: x86_64-apple-darwin19.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Newt version:

Apache Newt
   Version: 1.7.0
  Git Hash: 80bcba7
Build Date: 2019-08-06_13:20

I tested different newt versions (latest 1.7, 1.8 ..) and I changed the git versions in the project.yml. But I was not able to build the example. What am I doing wrong? Any help would be appreciated :)

BTW, newt looks really like an awesome project!

Thanks, Nils

UPDATE: ----------------------------------------------------------------------------------------

I updated gcc to 9.3

gcc (Homebrew GCC 9.3.0_1) 9.3.0

And also updated newt :

Apache Newt 1.9.0-dev / b86d086-dirty / 2020-05-04_22:24

But I still get the same error message :/

Hi @NilsMinor ,

It looks like your version of gcc is using an old C standard by default (older than C11). This can be fixed by upgrading your version of gcc. Note: newt does not use gcc when building that target, it uses arm-none-eabi-gcc (cross compiler). You can check your gcc version with

arm-none-eabi-gcc -v

The recommended minimum gcc version for Mynewt is gcc 7.

Hi @ccollins476ad ,

thanks for your help. You were right, I used the wrong compiler + an old version ^^.

I updated my ar-none-eabi-gcc.

arm-none-eabi-gcc -v

I use now the latest version 9.2.1

I changed the same project to 1-latest and 0-dev and used newt 1.9.0-dev and 1.7.0 but when building the app I now get this error. What have I missed?

Thanks for your support, Nils

UPDATE -----------------------------------------------------------------------------------------

My goal ist to build a nimble firmware for an nrf52832 chip, but I started with the Arduino Blinky example to get started with newt ^^. I created a new target for nordic_pca10040 board and followed the https://mynewt.apache.org/latest/tutorials/blinky/nRF52.html example and it worked for me ! Any Idea what was wrong on the Arduino example build? I also noticed that the bsp nrf52dk is not part of the core repo (any more?) so this should maybe be changed in the docs. If I understand a bit more about the newt project I will create an PR to change this, I think this is allowed? ^^

BR, Nils
