Consistent failure when attempting to run the 'make all' command

[AlasdairAtKitronik]

I was trying out the module freezing process (shown here: https://github.com/mytechnotalent/MicroPython-micro-bit_How_To_Build_And_Freeze_Modules), but kept having issues with the 'make all' process not working.

I thought it might be the changes I was making, so cloned a fresh version of the bbcmicrobit/micropython repo and tried to build the firmware with no changes - same error. I have tried using Windows command line and the git bash environment - both consistently fail on the same section (I am using a Windows 10 machine).

This is the error message:

Is anyone able to shed light on why this fails? Are there extra steps which need to be taken before running the instructions in the README?

[microbit-carlos]

What version of gcc are you using? Sounds like it's not compiling as C++11.

[microbit-carlos]

Are you use the target was correctly set in Yotta?

[AlasdairAtKitronik]

My gcc version is 8.1.0 and I used the following line to set the target:

yt target bbc-microbit-classic-gcc-nosd

[AlasdairAtKitronik]

I did think the references to C++98 were a bit strange

[microbit-carlos]

Could you build with the verbose flags and copy the full output? that should show which flags were used.

[microbit-carlos]

I just built on Ubuntu with gcc 7.3.1 without issues, these are the steps I take:

git clone https://github.com/bbcmicrobit/micropython.git
cd micropython
yt clean
yt target bbc-microbit-classic-gcc-nosd
yt up
make all

[AlasdairAtKitronik]

This is the build with flags:
build_flags.txt

[AlasdairAtKitronik]

I followed exactly the same steps as you did for your Ubuntu build.

[AlasdairAtKitronik]

This is my gcc version output:

C:\Users\alasdair.trench\github\microbit-micropython-no-mods\micropython>gcc --version

[AlasdairAtKitronik]

Is there an issue because I have the MinGW-W64, and it says at the start of the build that "This program built for i386-pc-mingw32"?

[microbit-carlos]

I don't know sorry, maybe that is just the make program build info.

Based on the output though, sounds like you are building with gcc arm v5:

-- Found assembler: C:/Program Files (x86)/GNU Tools ARM Embedded/5.4 2016q3/bin/arm-none-eabi-gcc.exe

I'd recommend to update that.

This is your x86_64 gcc:

C:\Users\alasdair.trench\github\microbit-micropython-no-mods\micropython>gcc --version

[AlasdairAtKitronik]

Right, I'll try updating that - thanks

[AlasdairAtKitronik]

The update of GCC solved my inital issue - thank you.
It might be worth noting in the README that as the make process uses a 'grep' command it will require a Unix environment?
All building successfully now.
