I am preparing a patch for a package. I am following the manual section "14.6 Submitting Patches". The fifth suggestion is to build the package for multiple platforms.
I have added these to the system configuration file: module: virtualization package: qemu service (taken from 14.6 Submitting Patches): (service qemu-binfmt-service-type (qemu-binfmt-configuration (platforms (lookup-qemu-platforms "arm" "aarch64" "ppc" "mips64el")) (guix-support? #t))) When I try to do a system reconfigure I get this error: error: qemu-binfmt-service-type: unbound variable hint: Did you forget a `use-modules' form? The closest package I can find using `guix package -s` is proot but adding the module linux and the package proot does not solve this error message. What should I do to get the system reconfiguration to work?
