[Bug bootstrap/25665] New: build failure on ppc64-linux

[fxcoudert at gcc dot gnu dot org]

I'm trying to bootstrap GCC trunk on a "Linux 2.6.5-7.97-pseries64 #1 SMP Fri
Jul 2 14:21:59 UTC 2004 ppc64", and after configure by:

../gcc/configure --enable-languages=c,fortran --with-gmp=[...]
--enable-bootstrap

I get the following error:

/tmp/debug/ibin/./prev-gcc/xgcc -B/tmp/debug/ibin/./prev-gcc/

Did I miss something obvious? I ran through the ppc-specific install notes, but
noted nothing special. binutils are 2.15.90.0.1.1 20040303, which should be
enough (install notes specify binutils >= 2.15).

With newer binutils (2.16.1), what happens is:

Oh, the problem is different than you think.  The internal error in ld is an
binutils bug.  But cause of it is because you forgot to use the option
--with-cpu=default32 as your first stage compiler is a 32bit compiler by
default.

You can also work around that by using CFLAGS="-m64 -O2 -g".

But this is not a GCC bug at all.  Maybe it is a doc failure but how would we
know that the installed compiler is a 32bit one or a 64bit one.
