Failed to build ARDUINO_NANO_RP2040_CONNECT (mod_network_nic_type_nina_base not constant)

[ksprs]

Hi!

It seams there is a trouble with a build process for ARDUINO_NANO_RP2040_CONNECT as it failed with these messages:

micropython/extmod/network_ninaw10.c:831:13: error: initializer element is not constant .base = mod_network_nic_type_nina_base, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/kaspars/git/micropython/extmod/network_ninaw10.c:831:13: note: (near initialization for 'mod_network_nic_type_nina.base') make[3]: *** [CMakeFiles/firmware.dir/build.make:2624: CMakeFiles/firmware.dir/home/kaspars/git/micropython/extmod/network_ninaw10.c.obj] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [CMakeFiles/Makefile2:1383: CMakeFiles/firmware.dir/all] Error 2 make[1]: *** [Makefile:91: all] Error 2 -e See https://github.com/micropython/micropython/wiki/Build-Troubleshooting make: *** [Makefile:33: all] Error 1

What I did was:
git clone https://github.com/micropython/micropython.git cd micropython/ git submodule update --init lib/micropython-lib lib/pico-sdk lib/tinyusb lib/mbedtls lib/mynewt-nimble cd ports/rp2/ make -j4 BOARD=ARDUINO_NANO_RP2040_CONNECT

Am I missing something?

Can you try updating to a newer GCC version?

I ran into the same error building with buster/gcc 8.3.0. After @jimmo's suggestion, I upgraded to bullseye/gcc 10.2.1 which built fine.

I've just updated the micropython/build-micropython-arm docker build container to use Debian Bullseye - and gcc 10.2.1 - for latest. So this now successfully builds ARDUINO_NANO_RP2040_CONNECT:

> docker run -ti --rm -v $(pwd):/code -w /code micropython/build-micropython-arm bash -c "make -C mpy-cross && make -C ports/rp2 submodules all BOARD=ARDUINO_NANO_RP2040_CONNECT"

I also tagged the Buster variant so you can still use it (to check the build failure):

> docker run -ti --rm -v $(pwd):/code -w /code micropython/build-micropython-arm:buster bash -c "make -C mpy-cross && make -C ports/rp2 submodules all BOARD=ARDUINO_NANO_RP2040_CONNECT"

Perfect! This solved the problem, thanks!
