Cross-Configuration |
Cross-Installation |
|
|
|
You need a cross-compilation toolchain for your target including gcc |
|
(2.0 or later). |

The first step in cross-installation is the cross-configuration. A |
|
few tests made by the configure script do not work in a |
cross-compilation situation. You have to provide the results of these |
cross-compilation situation. You have to provide the results of these |
tests by hand. E.g., if you compile for a 386 architecture processor: |

|
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. |
