Hello. Efraim Flashner said that the garbled output while building vim disappeared when he updated it. It has been two years and both vim and vim-full have been updated in guix since the last comment on this issue.
Checking cuirass, there is no garbled output: https://ci.guix.gnu.org/log/dnj9wljcck9vdwgp7dwxk00qnnk1g3c5-vim-full-8.2.0411 https://ci.guix.gnu.org/log/yajzgb2zlkklg5l9cpnsimrsjzmvq5x2-vim-8.2.0411 Building locally, My terminal survived and didn't notice any output getting garbled. (i am using emacs-vterm) ----- $ guix --version guix (GNU Guix) 2971ed57345ee4e00058efeaf27c6a0790fdc9dd $ guix build vim --no-substitutes $ guix build vim-full --no-substitutes ----- Going to go ahead and close out.
