# GUIX_BUILD_OPTIONS should be empty

#
# GUIX_BUILD_OPTIONS is an environment variable recognized by guix commands that
# can perform builds. This seems like what we want instead of
# ADDITIONAL_GUIX_COMMON_FLAGS, but the value of GUIX_BUILD_OPTIONS is actually
# _appended_ to normal command-line options. Meaning that they will take
# precedence over the command-specific ADDITIONAL_GUIX_<CMD>_FLAGS.
#
# This seems like a poor user experience. Thus we check for GUIX_BUILD_OPTIONS's
# existence here and direct users of this script to use our (more flexible)
# custom environment variables.
if [ -n "$GUIX_BUILD_OPTIONS" ]; then
cat << EOF
Error: Environment variable GUIX_BUILD_OPTIONS is not empty:
'$GUIX_BUILD_OPTIONS'
Unfortunately this script is incompatible with GUIX_BUILD_OPTIONS, please unset
GUIX_BUILD_OPTIONS and use ADDITIONAL_GUIX_COMMON_FLAGS to set build options
across guix commands or ADDITIONAL_GUIX_<CMD>_FLAGS to set build options for a
specific guix command.
See contrib/guix/README.md for more details.
