This file, ./MISC/Amiga/README.amiga, describes the necessary steps to get 
the FLEX 2.5.1 program up and running on the Commodore AMIGA with the 
help of SAS/C++ 6.51 and SMake 6.50.  Also it describes the contents of the 
subdirectory ./MISC/Amiga, where `.' denotes the root directory of the 
standard installation of FLEX 2.5.1. 
 
 
FILES ADDED FOR INSTALLING FLEX 2.5.1 ON THE AMIGA 
 
The standard distribution of FLEX 2.5.1 is assumed to be installed on 
your AMIGA computer.  `Installed' means that all source files from the 
original archive are present in a root directory (denoted by `.' in what 
follows) and, if appropriate, one or more subdirectories, on your machine. 
 
The original source files are totally left untouched, the necessary changes 
are applied in the form of `change files'.  For installing FLEX 2.5.1 on 
the AMIGA, several additional files come with this patch.

HOW TO INSTALL FLEX 2.5.1 ON THE AMIGA 
 
Copy all files from ./MISC/Amiga to the root directory of the FLEX 2.5.1 
distribution and edit `SMakefile' as it instructs you.  There shouldn't be 
too many changes necessary.  Then say "make bootflex".  This creates a 
preliminary version of FLEX 2.5.1 without using itself. 
 
WARNING: Don't say "make flex" yet.  Any pre-2.5 version of FLEX will fail 
on the file `scan.l' due to some new features only present in FLEX 2.5. 
 
Then say "make flex".  At least once the FLEX program created in the first 
step will be used.  To make sure that everything is alright, finally say 
"make check".  If you change the code, you should also say "make bigcheck" 
for some more thorough testing. 
 
When you are satisfied with the results, say "make install".  This will 
copy the `flex' binary, the `libfl.lib' file, and the `FlexLexer.h' header 
to the paths specified in the `SMakefile'. 
 
Finally, you should say "make clean" to remove all intermediate files from 
the root directory.  "make veryclean" also removes `flex' and `scan.c'. 
 
 
TROUBLE SHOOTING 
 
FLEX 2.5.1 was ported to the AMIGA and tested with the following setup: 
 
	AMIGA 2000 
	GVP G-Force 030/50/50/8 
	SAS/C++ 6.51 
	SED 2.05 
	BISON 1.22 
	WMERGE from the CWEB distribution 
 
Should you encounter problems with this AMIGA patch for FLEX 2.5.1 or 
should you have ideas for further improvements, like using GnuMake instead 
of SMake, contact the author of this contribution
