The first step in cross-installation is the cross-configuration. A |

| |
After the cross-configuration you type |
| |
|
| |
make gforths |
| |
|
| |
This produces the gforth engines for the target. |
| |
|
| |
The next step is to transfer everything to the target; on the target, |
| |
you do |
| |
|
| |
make |
| |
|
| |
to complete building gforth. If you do not have a make on the target, |
| |
run |
| |
|
| |
make -n |
| |
|
| |
on the host; manually execute on the target the last command output by |
| |
"make -n" (GFORTHD=...); the other commands output by "make -n" are |
| |
not necessary unless you have changed the Gforth sources. You can |
| |
then check and benchmark Gforth with |
| |
|
| |
make check |
| |
make bench |
| |
|
| |
or equivalent. Finally, perform |
| |
|
| |
make install |
| |
|
| |
or the equivalent commands on the target. |
