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 ".,/usr/local/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 ( %-/ +------- +Testing gawk with the included shell-scripts and .awk-files is not +possible. As far as I found out this is a Shell problem (shell- +metas), not a gawk problem. Using gawk from the commandline requires +modifications, too. To perform at least some of the tests I'd +suggest: + + make >amitest -n bigtest + +then modifying 'amitest' to work with your shell and + + execute amitest + +All tests that are depending on UNIX-shell specifics will fail (eg. +redirection of stderr: stderr and stdout are identical on the Amiga). +If I really have the time (currently I'm finishing my studies) I'll +write an amiga-script for the tests ... + +Despite testing is not a thankful task, `gawk' works and I found it +very useful for tasks where both shell scripts and C-programs are +inadequate. |
