- Subject: Gawk-2.14 -- Amiga-Port, the 2nd
-
- Gawk on the Amiga has been compiled and tested using the Amiga port
- of gcc by Markus Wild (wild@nessie.cs.id.ethz.ch). I recommend the use
- of this compiler (at least v2.2.2) because the provided environment
- (includes, libs, binutils) allows straight-forward porting of BSD/UNIX
- programs. Gcc compiled programs access/emulate UNIX syscalls via a
- shared library (ixemul.library); thus, only minimal changes to the
- source are necessary. That release also provides a `sh'- command. If
- no `sh'-command is available or another compiler is being used,
- `config.h' and `Makefile' are to be created by hand. Since I'm afraid
- that none of the Amiga-specific make-commands handles UNIX-style
- makefiles correctly I suggest the use of Dennis Vadura's`dmake',
- which is available on the Amiga (v3.6). I'm currently using dmake v3.8
- (a hack) or GNU make v3.62 (another hack :), which even allows
- to start multiple make jobs! Thanx to Markus!).

- Machine Configuration (obsoleted by gawk 2.16)
- ---------------------
- Only copy the following into config/amiga:
-
- Amiga under AmigaOS with gcc
- DOPRNT_MISSING 1
- ENVSEP ','
- DEFPATH ".,/gnu/lib"
- HAVE_UNDERSCORE_SETJMP 1
- SRANDOM_PROTO 1
- STDC_HEADERS 1
-
- The gcc compiler and the compiled executables are working under
- AmigaOS 1.2/1.3 as well as AmigaOS 2.x. However, some very special
- functions of ixemul.library currently require AmigaOS 2.x to work
- properly.
-
-
- How to compile (obsoleted by gawk 2.16)
- --------------
- Compiling and installing on the Amiga rather clones the UNIX-
- installation:
-
- After you have extracted the `gawk' distribution, `cd' to `gawk-
- 2.14'. Look in the `config' subdirectory for a file that matches your
- machine (in this case: `amiga', if the gawk maintainers put it there
- :).
-
- If you find such a file, run the command:
-
- sh configure amiga
-
- This produces a `Makefile' and `config.h' tailored to your system.
- You may wish to edit the `Makefile' to use a different C compiler,
- such as `gcc', the GNU C compiler (recommended), if you have it.
- You may also wish to change the `CFLAGS' variable, which controls
- the command line options that are passed to the C compiler (such as
- optimization levels, or producing `resident'-able code)
-
- After you have configured `Makefile' and `config.h', type:
-
- make
-
- and shortly thereafter (a little bit longer on a 7MHz machine >:->,
- you should have an executable version of `gawk'. That's all there is
- to it!
-
- Testing
- -------
- Gawk succeeds in all tests, but not with 'make test'. When executing
- the tests by hand (e.g. 'make swaplns' and so on) gawk runs all tests
- ok except for the following:
- - argarray, awkpath: these do not work due to insufficient environment
- variable handling by pdksh ('bin:sh')
- - poundbang, regtest: pdksh refuses to handle the #! statement
- properly
- Modifying these tests in a way that only *gawk-features, not *sh-
- features are tested, it is found that gawk succeeds here too.
- - manyfiles: (error: too many open files) ixemul.library v39.45 uses
- OPEN_MAX=64; manyfiles required at least OPEN_MAX=106
- This may only be overcome when mwild releases a new ixemul.library.
- Changing the number '100' in the 'manyfiles::'-target in
- 'test/Makefile' to some value <= 58 (depends on the number of
- currently open files in ixemul.library) gawk tests successfully, too.
