Hello Guix team, I can reproduce this issue and you will find my attempt to fix the building with the attached patch. I'm not used to this kind of bug fix so do not hesitate to correct me. During the building process, meson complains about the existence of positional arguments in the function i18n.merge_file. These arguments are no longer needed. > ../virt-viewer-11.0/data/meson.build:4:7: ERROR: Function does not take positional arguments. Additionaly, the source code has moved. I modified the source repository accordingly. Kind regards, Arnaud.
