| 24 | is missing and regeneration failed: |

| 27 | aborted with exit code $status. |
| 28 | |
| 29 | Try to re-run 'gforth-update-image' manually to |
| 30 | see what is wrong. Also please report this |
| 31 | problem to <discussion@lists.qi-hardware.com> |
| 32 | and/or <dvdkhlng ta gmx tod de>. |
| 33 | |
| 34 | As a workaround, you can run a kernel-only Gforth |
| 35 | (with reduced functionality), using: |
| 36 | |
| 37 | $binary -i @kernel_fi@ |
| 38 | EOF |
| 39 | |
| 40 | exec false |
| 41 | } |
| 42 | |
| 43 | if ! [ -f "$GFORTH_FI" ]; then |
| 44 | do_update |
| 45 | fi |
| 46 | |
| 47 | # if everything is ok, we'll come here and run the actual Gforth executable |
| 48 | # (gforth.real, gforth-fast.real etc.) |
| 49 | exec "$binary" "$@" |
