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
