Problem building on FreeBSD 3.2: "Alignment not a power of 2"

[Chip Olson]

I'm trying to build 2.95.2 on a FreeBSD 3.2 machine, and am getting the
following results:

I saw a reply to a similar problem that suggested that the assembler was
out of date. I'm using gas 2.9.1, which is what comes with binutils 2.10.1;
is there something newer I should be using?

Sadly, upgrading the OS version isn't an option.

If gas says it's from binutils 2.9.1, you've got the wrong gas.  The
one in binutils 2.10.1 says 2.10.1.

I suppose that should have been kind of obvious. :-)

However, after I built and installed gas 2.10.1, I got the exact same
result.

Did you configure GCC --with-gnu-as?

Same result there too. I should probably mention that I'm specifying a host
type (i386-unknown-freebsd), because my machine's uname output is something
completely different. It's my development machine here at work, and our
product runs on a slightly modified FreeBSD kernel, hence my machine does
too. The modifications are all in the networking code, however. I doubt
this has anything to do with the problem, but I've certainly been wrong
before. :-)

Hmm...  Well, then it may be that the bug is in GCC 2.95.2.  I do
build development snapshots of GCC using GNU as on FreeBSD 3 boxes
weekly, but I'm not sure I've ever had a chance to attempt to build
GCC 2.95.2 on the FreeBSD boxes I've got guest access to.

My next suggestions are to try to go without GNU as (using the native
assembler), or to try a development snapshot with GNU as.

Well, since I was using the native assemble to begin with, I decided to go
with your second suggestion instead. With gcc-20010205, it got a *lot*
further, but failed at this point:

[...]
(MAKE="make"; srcdir=`cd ../../gcc-20010205/gcc/fixinc && pwd` ;

Interestingly, stage1/xgcc is definitely still there at this point, and
it's been chewing along merrily recompiling itself for quite a while when
this happens. The contents of machname.h are:

#define MN_NAME_PAT "\\<i386\\>|\\<unix\\>"

I suspect that my machine's non-standard setup has something to do with
this (anything that seems to be checking the host type makes me nervous on
this machine), but I don't know enough about what the compilation process
is trying to accomplish here. 

Many thanks,

Is srcdir == objdir?  Try a separate directory.  This has been known
to not work lately.  We're working to fix it.

I am using a separate directory. Maybe I should try it the other way? :-)
