      2 This file, ./MISC/Amiga/README.amiga, describes the necessary steps to get
      3 the FLEX 2.5.1 program up and running on the Commodore AMIGA with the
      4 help of SAS/C++ 6.51 and SMake 6.50.  Also it describes the contents of the
      5 subdirectory ./MISC/Amiga, where `.' denotes the root directory of the
      6 standard installation of FLEX 2.5.1.

      9 FILES ADDED FOR INSTALLING FLEX 2.5.1 ON THE AMIGA
     10 
     11 The standard distribution of FLEX 2.5.1 is assumed to be installed on
     12 your AMIGA computer.  `Installed' means that all source files from the
     13 original archive are present in a root directory (denoted by `.' in what
     14 follows) and, if appropriate, one or more subdirectories, on your machine.
     15 
     16 The original source files are totally left untouched, the necessary changes
     17 are applied in the form of `change files'.  For installing FLEX 2.5.1 on
     18 the AMIGA, several additional files come with this patch.

     29 HOW TO INSTALL FLEX 2.5.1 ON THE AMIGA
     30 
     31 Copy all files from ./MISC/Amiga to the root directory of the FLEX 2.5.1
     32 distribution and edit `SMakefile' as it instructs you.  There shouldn't be
     33 too many changes necessary.  Then say "make bootflex".  This creates a
     34 preliminary version of FLEX 2.5.1 without using itself.
     35 
     36 WARNING: Don't say "make flex" yet.  Any pre-2.5 version of FLEX will fail
     37 on the file `scan.l' due to some new features only present in FLEX 2.5.
     38 
     39 Then say "make flex".  At least once the FLEX program created in the first
     40 step will be used.  To make sure that everything is alright, finally say
     41 "make check".  If you change the code, you should also say "make bigcheck"
     42 for some more thorough testing.
     43 
     44 When you are satisfied with the results, say "make install".  This will
     45 copy the `flex' binary, the `libfl.lib' file, and the `FlexLexer.h' header
     46 to the paths specified in the `SMakefile'.
     47 
     48 Finally, you should say "make clean" to remove all intermediate files from
     49 the root directory.  "make veryclean" also removes `flex' and `scan.c'.
     50 
     51 
     52 TROUBLE SHOOTING
     53 
     54 FLEX 2.5.1 was ported to the AMIGA and tested with the following setup:
     55 
     56 	AMIGA 2000
     57 	GVP G-Force 030/50/50/8
     58 	SAS/C++ 6.51
     59 	SED 2.05
     60 	BISON 1.22
     61 	WMERGE from the CWEB distribution
     62 
     63 Should you encounter problems with this AMIGA patch for FLEX 2.5.1 or
     64 should you have ideas for further improvements, like using GnuMake instead
