After configuration, type |

|
or however your gcc is called; because configure needs cc to find out some |
make |
parameters, and there may be differences in what is obtained from gcc and |
|
from ghe default cc. |
Now you can check whether your shiny new Forth system works. Say |
|
|
|
make test |
|
|
|
You can run some benchmarks with |
|
|
|
make bench |
|
|
|
and compare them with the results in Benchres and in the manual. |
|
|
|
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. |
|
|
|
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, just concatenate the files |
|
gforth.info-* ('cat gforth.info-*' under Unix). |

Configuration Options |
|
|
|
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. You need a VPATH-capable 'make' |
|
(e.g., GNU make) for this. (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). |
|

tried gave the best results for various machines. |

After, configuration, type |
Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you |
|
should say so during configuration. E.g.: |
|
|
make |
env CC=gcc-2.7.1 ./configure |
|
|
If your make has trouble with the Makefile, "make gforth" might work. |
|
|
|
If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type |
|
|
|
make GCC=<whatever you call your gcc> |
|
|
|
instead. |
|
|
|
Now you can check whether your shiny new Forth system works. Say |
|
|
|
make test |
|
|
|
You can run some benchmarks with |
You can also pass additional options to gcc in this way, e.g., if you |
|
want to generate an a.out executable under Linux with gcc-2.7.0: |
|
|
make bench |
env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure |
|
|
and compare them with the results in Benchres and in the manual. |
You can change the sizes of the various areas used in the default |
|
image `gforth.fi' by passing the appropriate Gforth command line |
|
options in the FORTHSIZES environment variable: |
|
|
If everything is all right, you may want to install gforth. Type |
env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=16k --return-stack-size=16k --locals-stack-size=16k" ./configure |
|
|
make install |
|
|
|
You have to make an entry in the info directory file manually. |
|
|
|
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 |
|
|
|
|
The line above reaffirms the default sizes. Note that the locals |
|
stack area is also used as input buffer stack. |

2) "%s: Checksum of image ($13579b) does not match the executable ($2468a) |
|
The Gforth installer should look into the INSTALL file" |
|
|
|
A fixed-address image is not only fixed with respect to its base |
|
address, but also with respect to certain addresses in the gforth |
|
executable and the threading method. These things are encoded in a |
|
checksum. |
|
|
|
If the checksum of the executable and the checksum of the image are |
|
not equal, you get the message above. This can be caused, e.g., by |
|
trying to run an image produced for a direct threading system on an |
|
indirect threaded system. |
|
|
|
Chances are that you unintentionally tried to execute an image from |
|
the wrong directory. As a remedy, you can specify Gforth's search |
|
path with the "-p" command line option and with the GFORTHPATH |
|
environment variable. |
|
|
|
On the other hand, if you need to solve the problem by creating a new |
|
fixed-address image, you can use the steps described above. |
