13.5.2 “How can I wholly disable the compiler output cache?”

To permanently disable the compiler output cache for all future runs of ASDF, you can:

mkdir -p ~/.config/common-lisp/asdf-output-translations.conf.d/
echo ':disable-cache' > \
~/.config/common-lisp/asdf-output-translations.conf.d/99-disable-cache.conf

This assumes that you didn’t otherwise configure the ASDF files (if you did, edit them again), and don’t somehow override the configuration at runtime with a shell variable (see below) or some other runtime command (e.g. some call to asdf:initialize-output-translations).

To disable the compiler output cache in Lisp processes run by your current shell, try (assuming bash or zsh) (on Unix and cygwin only):

export ASDF_OUTPUT_TRANSLATIONS=/:

To disable the compiler output cache just in the current Lisp process, use (after loading ASDF but before using it):

(asdf:disable-output-translations)

Note that this does NOT belong in a .asd file. Please do not tamper with ASDF configuration from a .asd file, and only do this from your personal configuration or build scripts.
