When we was running the followed code in my ubuntu system:

nix develop git+https://git.m-labs.hk/m-labs/artiq-zynq\?ref=release-8

We met a problem in install phase:

error: builder for '/nix/store/fwvyqmllynxks4brv79x0f2qdfyd6hpd-binutils-arm-2.30.drv' failed with exit code 2;

What can I do to fix the problem.

Thank you for your help in advance

fsagbuya OK, maybe my system environment is broken. I will try it later. Thank you

    fsagbuya Are you building this from source? You might want to try adding the binary cache available on Hydra.

    Source builds (without substituter) are still supposed to work though. Last time I checked they did.
