Gforth image $GFORTH_FI
is missing and regeneration failed:
'$dirname/gforth-update-image'
aborted with exit code $status.
Try to re-run 'gforth-update-image' manually to
see what is wrong. Also please report this
problem to <discussion@lists.qi-hardware.com>
and/or <dvdkhlng ta gmx tod de>.
As a workaround, you can run a kernel-only Gforth
(with reduced functionality), using:
$binary -i @kernel_fi@
EOF
exec false
}
if ! [ -f "$GFORTH_FI" ]; then
do_update
fi
# if everything is ok, we'll come here and run the actual Gforth executable
# (gforth.real, gforth-fast.real etc.)
exec "$binary" "$@"
