Hi,
I'm building gcc 4.6.2 (C and C++) on AIX 5.2 to compile for AIX
4.3.3. I copied libraries and /usr/ccs/bin (as, nm, ld and others)
from 4.3.3 to sysroot/ directory on AIX 5.2.
AS_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/as \
LD_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/ld \
STRIP_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/strip \
RANLIB_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/ranlib \
AR_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/ar \
NM_FOR_TARGET=/home/jd/xcomp/sysroot/usr/ccs/bin/nm \
This makes the build to differ from the normal cross GCC case
where GNU binutils are used as the target binutils. Here the
native AIX 4.3.3 binutils are used on a AIX 5.2 cross host
as the target binutils. So my stupid question is whether this
choice should work at all?
--with-as=/home/jd/xcomp/sysroot/usr/ccs/bin/as \
--with-ld=/home/jd//xcomp/sysroot/usr/ccs/bin/ld \
These AIX 4.3.3 'as' and 'ld' seemingly don't crash on AIX 5.2
but :
/home/jd/xcomp/build/./gcc/xgcc -B/home/jd/xcomp/build/./gcc/
-B/opt/xgcc/gcc-4.6.2/powerpc-ibm-aix4.3.3.0/bin/
-B/opt/xgcc/gcc-4.6.2/powerpc-ibm-aix4.3.3.0/lib/ -isystem
/opt/xgcc/gcc-4.6.2/powerpc-ibm-aix4.3.3.0/include -isystem
/opt/xgcc/gcc-4.6.2/powerpc-ibm-aix4.3.3.0/sys-include
--sysroot=/home/jd/xcomp/sysroot
what about the native AIX 4.3.3 'ld' understanding where the
target library stuff is? What the libgcc configure understood
about the target libraries?
If behaving normally, building GNU binutils for the AIX 5.2
$host and targeting to the AIX 4.3.3 $target and configuring
them using '--with-sysroot=' to search from $sysroot for the
AIX 4.3.3, there wouldn't be these suspicicions and stupid
questions... And any crash in the build would be a clear bug
but it is hard to say what this case really is.
