Bug in compiling

[Robin Johnson]

Greetings,

While mass compiling a new kernel for my slew of systems, I had an unusual
problem

gcc barfs and gives this huge error:

Now I know the exact source compiled and booted perfectly already. All I
did was tar up my source tree, and copy it to another system. It was on
/root/kern3/linux-2.4.19-pre4-ac3 on the first system, and
/usr/src/linux-2.4.19-pre4-ac3 on the second system. I ran 'make
distclean', copied in the config file, which is almost identical, ran
'make oldconfig dep bzImage'. Then in compiling kernel/exec_domain.c I get
that massive set of error messages that don't make sense at all, as they
have compiled perfectly only 20 minutes before.

Any ideas?

All EXPORT_SYMBOL.  You would get that behaviour if gcc did not
recognise EXPORT_SYMBOL as a macro.  Probably random data corruption.

Of the pair of machines, I upgraded one of them to GCC 3.0.4, while
leaving the other at 2.95.3.

The identical source and config file compiles fine on the one, but not on
the other. It gives that exec_domain slew.c of errors.

So is this a GCC bug that I have located, or something more with the
kernel?, as Documentation/Changes lists GCC 2.95.3 at the minimal version
required.

I would like to avoid the GCC3 tree as it stands presently, as I have some
C++ code that can not be ported at this time to work with GCC3, and only
works with GCC2.95.3.

Any ideas?

Thanks in advance.

On the failing system,

cd /usr/src/linux-2.4.19-pre4-ac3/kernel
gcc -D__KERNEL__ -I/usr/src/linux-2.4.19-pre4-ac3/include -Wall \
        -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer \
        -fno-strict-aliasing -fno-common -pipe \
        -mpreferred-stack-boundary=2 -march=i686 \
        -DKBUILD_BASENAME=exec_domain -DEXPORT_SYMTAB \
	-E -c exec_domain.c -o exec_domain.i

and send exec_domain.i to kaos@ocs.com.au (not the list).
