meson.build:1048:19: ERROR: Unknown variable "tmp".

This looks like a bug in meson.build at the quoted line devmapper_version = '1.0.0' devmapper_dep = dependency('devmapper', version: '>=' + devmapper_version, required: false) if not devmapper_dep.found() # devmapper is missing pkg-config files in ubuntu, suse, etc devmapper_dep = cc.find_library('devmapper', required: false) if devmapper_dep.found() and not cc.has_function('dm_task_run', dependencies: tmp) devmapper_dep = dependency('', required: false) endif endif it is indeed referencing a "tmp" variable that doesn't exist. What OS distro are you using ? This happens because you are missing the required version of devmapper library. Either you need to install more build pre-requisite packages, or your distro is different from what we've tested Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
