Can't build for picosystem

[Quentie]

Hi I'm trying to follow https://github.com/32blit/32blit-sdk/blob/master/docs/pico.md to setup a Dockerfile to build for my new picosystem. But can't get it working :( Could anyone give me a tip?

Here my Dockerfile:

FROM ubuntu:24.10

RUN apt update \
    && apt install --yes --no-install-recommends \
       git gcc g++ gcc-arm-none-eabi cmake make \
       python3 python3-pip python3-setuptools \
       libsdl2-dev libsdl2-image-dev libsdl2-net-dev unzip \
    && pip3 install 32blit --break-system-packages \
    && git clone https://github.com/32blit/32blit-sdk \
    && cd 32blit-sdk \
    && mkdir build \
    && cd build \
    && cmake .. -D32BLIT_DIR=`pwd`/.. -DPICO_SDK_FETCH_FROM_GIT=true -DPICO_EXTRAS_FETCH_FROM_GIT=true -DPICO_BOARD=pimoroni_picosystem \
    && make \

If I build the docker image using docker build - < Dockerfile I get

-- Build files have been written to: /32blit-sdk/build
1005.8 [  0%] Building CXX object 32blit/CMakeFiles/BlitEngine.dir/audio/audio.cpp.obj

It works like a charm if I build for linux and not the picosystem:

FROM ubuntu:24.10

RUN apt update \
    && apt install --yes --no-install-recommends \
       git gcc g++ gcc-arm-none-eabi cmake make \
       python3 python3-pip python3-setuptools \
       libsdl2-dev libsdl2-image-dev libsdl2-net-dev unzip \
    && pip3 install 32blit --break-system-packages \
    && git clone https://github.com/32blit/32blit-sdk \
    && cd 32blit-sdk \
    && mkdir build \
    && cd build \
    && cmake .. \
    && make \

Hmm, I'm guessing that with --no-install-recommends you're going to need to specify the stdlib packages. (libnewlib-arm-none-eabi/libstdc++-arm-none-eabi-newlib?)

Thanks for your help @Daft-Freak! That worked like a charm!
