Gawk on Atari has been compiled and tested using gcc compiler
(versions 1.4 and 2.2.2) both with and without -mshort flag. Other
compilers can be used but if sizeof(pointer) != sizeof(int) this
code will not compile correctly with non-ANSI compiler (prototypes
Compiled executables were tested and with minor modifications, due
to differences in environment and/or shell, succesfully completed
at least the following tests:
awf, pearls, resub, chem, swaplns, delete, messages, argarray,
longwrds, getline, inftest, spiece2top, fstabplus, compare, arrayref,
rs, fsrs, rand, fsbs, negexp, ugh2, asgext, anchgsub, splitargv,
fieldwidths, ignorecase, posix, manyfiles, igncfs, lisp, regtest,
Nearly all of these test do not require any adjustments to run, but a
modified test suite with a driving Makefile (for gulam) is available
on a request from Michal Jaegermann, ntomczak@vm.ucs.ualberta.ca,
Setup for Atari assumes that gawk will be used under TOS. In
particular atari/system.c source is for a system function which nicely
cooperates with gulam shell and pipes are simulated with temporary
files. If you plan to run gawk under MiNT then you likely want a
different system function and real pipes. For that purpose do not
define SYSTEM_MISSING in a configuration file and do not define
PIPES_SIMULATED in io.c file. Please note that in the later case gawk
calls, in gawk_popen(), a function execl() with a hard-coded name of
"/bin/sh". You want likely to change that to get a name and some
arguments from an environment variable. This was not done here in
order to avoid changes which may prove troublesome in a general
distribution. Subdirectory ./atari contains also a file textrd.c with
a bug fix for old versions of gcc libraries. This bug is currently
fixed and the file is not used, but it is left as a convenience for
those who may not updated yet their libraries.
