Subject: /usr/obj/elf, /usr/obj/aout, /usr/obj - breaks make all vs make buildworld, and other things.  Time to make elf the default ?
Sender: owner-freebsd-current@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.ORG

    If I do a 'make buildworld', the object tree is created in /usr/obj/elf
    rather then /usr/obj.

    If I then want to make the world again, but without cleaning anything,
    'make' alone will not work.  Instead, 'make -DNOCLEAN -DNOTOOLS' must be
    used.

    The difference appears to be in /usr/src/Makefile.inc0. It does not set
    up MK_ENV for certain backend targets.

#
# A generic rule for the backend targets.
#
${BKTGTS} :
        @cd ${.CURDIR}; ${MAKE} ${.TARGET} 

    Is there any reason why we can't have it setup the MK_ENV ?  As in the
    below ?

    Now, I realize that if you cd somewhere deep into /usr/src and type make,
    it will not use the correct obj tree either.  So the question is, is it
    time to make elf the default ( i.e. /usr/obj ) and just special case 
    a.out ( i.e. /usr/obj/a.out ) ????

    My personal opinion is:  yes, ELF should now be the default without any
    OBJFORMAT munging.  It would be relatively simple to have the top level
    make check whether the user's machine is ELF or not, and to only allow
    the user to ( at this point ) convert his machine from a.out to elf before
    the user is allowed to compile random source.
