>Description:
Condider the following Makefile (where prog.c is hello-world):
.POSIX:
prog: prog.o
echo $(%POSIX)
$(CC) -o prog prog.o
clean:
rm -f prog prog.o
When I run 'make' this is what is done:
$ make
cc -O -pipe -c prog.c
echo 1003.2
1003.2
cc -o prog prog.o
However, /usr/share/mk/sys.mk says:
# from: @(#)sys.mk 8.2 (Berkeley) 3/21/94
# $Id: sys.mk,v 1.43 1998/09/15 05:24:01 obrien Exp $
unix ?= We run FreeBSD, not UNIX.
# If the special target .POSIX appears (without prerequisites or
# commands) before the first noncomment line in the makefile, make shall
# process the makefile as specified by the Posix 1003.2 specification.
# make(1) sets the special macro %POSIX in this case (to the actual
# value "1003.2", for what it's worth).
#
# The rules below use this macro to distinguish between Posix-compliant
# and default behaviour.
...
.if defined(%POSIX)
CC ?= c89
.else
CC ?= cc
.endif
CFLAGS ?= -O -pipe
...
Thus, I expect CC to be c89 (I can't see where CC is set from actually).
What's more, as soon as c89 is used, CFLAGS must not contain non-POSIX
compiler options like -pipe, because otherwise c89 rightfully barfs:
$ make CC=c89
c89 -O -pipe -c prog.c
Illegal option -p
usage: c89 [-c] [-D name[=value]] [...] [-E] [-g] [-I directory ...]
[-L directory ...] [-o outfile] [-O] [-s] [-U name ...] operand ...
*** Error code 64
Stop.
I tried 'make -d A' for debugging, but CC=cc seems to be set in some
global place:
$ make -d A
Global:.MAKEFLAGS = -d
Global:.MAKEFLAGS = -d A
Global:.TARGETS =
Caching /usr/share/mk...done
expanding "sys.mk".../usr/share/mk/sys.mk
Global:MAKEFILE = /usr/share/mk/sys.mk
Global:unix = We run FreeBSD, not UNIX.
Global:X11BASE = /usr/X11R6
Global:AR = ar
Global:ARFLAGS = rl
Global:RANLIB = ranlib
Global:AS = as
Global:AFLAGS =
Global:CC = cc <----- why is this not c89?
...etc
It seems the .if defined(%POSIX) doesn't work properly. Or I have
overlooked something. Or something funny is going on.
Regards,
Jens
