Compile error on Mac Mojave #1685

Open charuwalee opened 5 years ago

charuwalee commented 5 years ago

Hi,

I've tried to install mynewt on Mac Mojave version 10.14.3. Every went well until I tried to create a new project. I followed the instructions from https://mynewt.apache.org/latest/get_started/project_create.html and got tens of error messages when I tried to test the project package by using command newt test @apache-mynewt-core/sys/config. The snapshot of an example of error messages are as shown in the pictures below.

Could anyone give a hint of what went wrong and how to fix this?

Thank you in advance!! Charuwalee

Hi,

You need to use Xcode 9, I think this is related to deprecation of 32bit binaries (and newt test is using native target which is 32bit)

I think we need to keep this open and fix it, a Mojave install breaks newt sim, which most of the docs suggest using. Also, it's complicated to move back to Xcode 9 and we should at least have instructions to do so.

Also, I'm wondering if we shouldn't take this oppty to use QEMU, or run 32-bit in QEMU. The support for STM32* etc is there, but pretty weak (and not distributed in homebrew binaries), but we could look at emulating a X86 system by default and running sim in there?
