After configuration, type |

Now you can check whether your shiny new Forth system works. Say |

make test |

You can run some benchmarks with |

If everything is all right, you may want to install gforth. Type |
| |
|
| |
make install |
| |
|
| |
You have to make an entry in the info directory file manually (see |
| |
Installing Info Files, below). |
| |
|
| |
For paper documentation, print gforth.ps (a Postscript file (300dpi |
| |
fonts, i.e., it works, but does not produce best quality on better |
| |
printers)), or say |
| |
|
| |
make gforth.dvi |
| |
|
| |
and print the resulting file gforth.dvi. You can also get the |
| |
documentation in HTML format by typing |
| |
|
| |
make html |
| |
|
| |
If you prefer plain ASCII documentation, you can |
| |
|
| |
make doc/gforth.txt |
| |
|
| |
or just concatenate the files gforth.info-* ('cat gforth.info-*' under |
| |
Unix); the result of the latter option is a little worse. |

Configuration Options |
| |
|
| |
If you use GNU make, you can build in a directory different from the |
| |
source directory by changing to the build directory and invoking |
| |
configure thus: |
| |
|
| |
$srcdir/configure |
| |
|
| |
where $srcdir is the source directory. (Note that we tested this only |
| |
for installation; i.e., if you want to hack the Gforth sources, you |
| |
should probably build in the source directory). |
| |
|
| configure has the following useful parameters: |

You can change the sizes of the various areas used in the default |

image `gforth.fi' by passing the appropriate Gforth command line |
| make |
options in the FORTHSIZES environment variable: |
| |
|
| Now you can check whether your shiny new Forth system works. Say |
|

| make test |
|

|
| You can run some benchmarks with |
|
| |
|
| make bench |
env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=15872b --return-stack-size=15k --locals-stack-size=14848b" ./configure |
| |
|
| and compare them with the results in Benchres and in the manual. |
The line above reaffirms the default sizes. Note that the locals |
| |
stack area is also used as input buffer stack. |

| If everything is all right, you may want to install gforth. Type |
If C's "long long" do not work properly on your machine (i.e., if the |
| |
tests involving double-cell numbers fail), you can build Gforth such |
| |
that it does not use "long long": |
| |
|
| make install |
env ac_cv_sizeof_long_long=0 ./configure |
| |
|

Cross-Configuration |
| fonts, i.e., it works, but does not produce best quality on better |
|
| printers)), or say |
|
| |
|
| make gforth.dvi |
A few tests made by the configure script do not work in a |
| |
cross-compilation situation. You have to provide the results of these |
| |
tests by hand. E.g., if you compile for a 386 architecture processor: |
| |
|
| and print the resulting file gforth.dvi. You can also get the |
env ac_cv_sizeof_char_p=4 ac_cv_sizeof_short=2 ac_cv_sizeof_int=4 ac_cv_sizeof_long=4 ac_cv_sizeof_long_long=8 ac_cv_c_bigendian=no ./configure |
| documentation in HTML format by typing |
|
| |
|
| make html |
The ac_cv_sizeof_... variables give the sizes of various C types; |
| |
ac_cv_sizeof_char_p is the same as "sizeof(char*)" in C code. The |
| |
ac_cv_c_bigendian variable gives the byte order. |

| A Possible Problem |
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'. |
| |
|
| You need to read this only if you see a message like |
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: |
| |
|
| "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678 |
1. Add an INFOPATH environment variable. The easiest place to do |
| The Gforth installer should look into the INSTALL file" |
this is '/etc/profile', right next to PATH and MANPATH: |
| |
|
| Gforth supports both relocatable and fixed-address images. If you load |
INFOPATH=/usr/local/info:/usr/info |
| normal Forth code and save the image, you get a fixed-address |
|
| image. Producing a relocatable image is more difficult. |
|
| |
|
| Therefore, Gforth has only a relocatable image of the kernel |
|
| (kernal.fi), which is powerful enough to load the rest of |
|
| Gforth. However, loading the rest takes a noticable amount of time. To |
|
| avoid this delay (which would occur on every startup), the |
|
| installation procedure produces an image fixed at an address |
|
| determined at the Gforth run that produced the image. This |
|
| fixed-address image is loaded by default. On most OSs this works, |
|
| because the first chunk of memory is always allocated at the same |
|
| address. If the address changes, you get the message above. |
|
| |
|
| An image address change can be caused by a change of the gforth |
|
| executable, or by a change (upgrade) of the OS; in these cases you |
|
| just have to rebuild and reinstall the fixed address image with |
|
| |
|
| rm gforth.fi; make gforth.fi; make install |
|
| |
|
| If you get such a message with a different address in place of the |
|
| 0x5678 each time you try to start gforth, you cannot use fixed-address |
|
| images on your OS. In this case, send us a message so that we start |
|
| searching for a comfortable solution to this problem. In the |
|
| meantime, start gforth with |
|
| |
|
| gforth -i kernal.fi startup.fs |
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). |
