Oh... I saw what's happening... I was using `guix environment --manifest=manifest.scm` Being manifest: (specifications->manifest '("unzip" "zip" "git" "wget" "dfu-programmer" "dfu-util" "avr-toolchain" "glibc" "gcc-toolchain" "arm-none-eabi-toolchain")) Which are all the development packages needed by QMK keyboard. I can replicate what you did and it works. May it be conflicting with other packages? Or using environment like that isn't doing what I expect? ElenQ Technology Ethical Innovation
