Hmm, but since CPUTYPE isn't set at that time too, there shouldn't be
the gcc-only -march flag, no?
Or is it the late macro expansion, that always confuses me.
Anyway, putting CC and CPUTYPE into make.conf solves my problems. But
the thing is, I only want these flags on some specific programs, not
all (especially CC=3Dicc).
Looking at MAKEFILE_LIST, it looks like I'm SOL
% make -V .MAKEFILE_LIST|tr ' ' \\n|sed '/\.\./d'
/usr/share/mk/sys.mk
/etc/make.conf
/usr/share/mk/bsd.compat.mk
/usr/share/mk/bsd.cpu.mk
Makefile
/usr/share/mk/bsd.prog.mk
/usr/share/mk/bsd.init.mk
/usr/share/mk/bsd.compat.mk
/usr/share/mk/bsd.own.mk
/usr/share/mk/bsd.libnames.mk
/usr/share/mk/bsd.nls.mk
/usr/share/mk/bsd.files.mk
/usr/share/mk/bsd.incs.mk
/usr/share/mk/bsd.links.mk
/usr/share/mk/bsd.man.mk
/usr/share/mk/bsd.dep.mk
/usr/share/mk/bsd.obj.mk
/usr/share/mk/bsd.own.mk
/usr/share/mk/bsd.subdir.mk
/usr/share/mk/bsd.init.mk
/usr/share/mk/bsd.sys.mk
Well, I could delete CFLAGS and force loading bsd.cpu.mk again, so this
Makefile kinda works:
CFLAGS=3D
CC=3Dicc
CPUTYPE=3Dpentium-m
=2Einclude <bsd.prog.mk>
=2Einclude <bsd.cpu.mk>
% make -V CFLAGS
-tpp6 -xiMK
% make -V .MAKEFILE_LIST|tr ' ' \\n|sed '/\.\./d'
/usr/share/mk/sys.mk
/etc/make.conf
/usr/share/mk/bsd.compat.mk
/usr/share/mk/bsd.cpu.mk
Makefile
/usr/share/mk/bsd.prog.mk
/usr/share/mk/bsd.init.mk
/usr/share/mk/bsd.compat.mk
/usr/share/mk/bsd.own.mk
/usr/share/mk/bsd.libnames.mk
/usr/share/mk/bsd.nls.mk
/usr/share/mk/bsd.files.mk
/usr/share/mk/bsd.incs.mk
/usr/share/mk/bsd.links.mk
/usr/share/mk/bsd.man.mk
/usr/share/mk/bsd.dep.mk
/usr/share/mk/bsd.obj.mk
/usr/share/mk/bsd.own.mk
/usr/share/mk/bsd.subdir.mk
/usr/share/mk/bsd.init.mk
/usr/share/mk/bsd.sys.mk
/usr/share/mk/bsd.cpu.mk
Am I asking for trouble using this construct? Thanks anyway for
pointing me to make(1), d'oh!
