 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

   You can run some benchmarks with

   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).

 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)

   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.
