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. |

Installing Info Files |
|
|
|
Info is the GNU project on-line documentation format. You can read |
|
info files either from within Emacs (Ctrl-h i) or using the |
|
stand-alone Info reader, 'info'. |
|
|
|
If you use the default install root of '/usr/local' then the info |
|
files will be installed in '/usr/local/info'. |
|
|
|
Many GNU/Linux distributions are set up to put all of their |
|
documentation in '/usr/info', in which case you might have to do a |
|
couple of things to get your environment set up to accommodate files |
|
in both areas: |
|
|
|
1. Add an INFOPATH environment variable. The easiest place to do |
|
this is '/etc/profile', right next to PATH and MANPATH: |
|
|
|
INFOPATH=/usr/local/info:/usr/info |
|
|
|
2. Create a file called 'dir' in 'usr/local/info'. Use the file |
|
'/usr/info/dir' as a template. You can add the line for gforth |
|
manually, or use '/sbin/install-info' (man install-info for details). |
