Hi, Pierre Neidhardt <[email protected]> skribis:

COLUMNS only helps if you wish to debug ‘guix build’ itself. It cannot influence Guile processes launched by the daemon, such as those that build derivations and the helper processes (‘guix substitute’, etc.). In most cases, we’re interested in backtraces coming from Guile processes that build derivations. For that, we need to set COLUMNS in the #:env-vars argument of ‘gexp->derivation’ or similar. HTH! Ludo’.
