Build error at wmake on FreeBSD

[yamori813]

Hi

I build OW on FreeBSD/i386 12.2R.

I have build error on wmake. I seem bld/wmake/postmake is not compatible BSD make.

% ./build.sh
Open Watcom build environment (CLANG version=10, CYEAR=2021)

cc -I../../watcom/h -o cretype.exe
cc: error: no input files
*** Error code 1

Stop.

wmake bootstrap build error

It is strange.
Please could you get more verbosed output from make on freeBSD?
It should be command line option like "-d A"
It looks like problem with $< macro that is blank for some reason to build cretype.exe.

[jmalak]

It seems I find out source of problem.
It looks like $< macro is defined only for implicit rules.
I replace it by $? even if it is not the same, but for our make file with only 1 dependent it works properly (it contains all dependents = only source file).
Please check it on FreeBSD.

This is work fine. But I don't know why. I don't detailed Makefile macro. sorry.

It looks like freeBSD make is not fully POSIX compliant.
Now wmake build make file uses POSIX construct working with freeBSD make.
It should be working in the future when freeBSD will be fully POSIX compliant.

[jmalak]

I add .POSIX directive which is required by POSIX standard.
I don't know if this fix your problem.

[jmalak]

I rework the wmake code a little bit to use POSIX setenv instead of putenv, commit 54a05bd .
I also set POSIX compliance version 200112L and setup make file to use POSIX standard by directive .POSIX:.
Please, check if a problems continue or if it is fixed.
