compile error 2.4.4pre6: inconsistent operand constraints in an `asm'

compile error 2.4.4pre6: inconsistent operand constraints in an `asm'

[axel]

Hallo,

after having had trouble with compilation due to old gcc version, i have
updated to gcc 3.0 and received the following error:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.4pre6/include -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe
-mpreferred-stack-boundary=2 -march=i586    -DEXPORT_SYMTAB -c sys.c
sys.c: In function `sys_gethostname':
/usr/src/linux-2.4.4pre6/include/asm/rwsem.h:142: inconsistent operand
constraints in an `asm'
make[2]: *** [sys.o] Error 1
make[2]: Leaving directory `/usr/src/linux-2.4.4pre6/kernel'
make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.4pre6/kernel'
make: *** [_dir_kernel] Error 2

I'm very thankful for any help,

Regards,
Axel Siebenwirth

Although bug reports about a kernel compiled with gcc-3.0 are welcome,
this is still not the recommended compiler. The recommended compiler is
gcc-2.91.66 (aka egcs-1.1.2), but for most people gcc-2.95.2 works as
well.

2.4.4pre6 only builds with gcc 2.96. If you apply the __builtin_expect fixes
it builds and runs fine with 2.95. Not tried egcs. The gcc 3.0 asm constraints
one I've yet to see a fix for.

So, should I upgrade to 2.96 from 2.95.3?

But, from http://gcc.gnu.org/gcc-2.96.html ...

   Please note that both GCC 2.96 and 2.97 are development versions; we
   do not recommend using them for production purposes. Binaries built
   using any version of GCC 2.96 or 2.97 will not be portable to systems
   based on one of our regular releases.


Does this still hold?

Thanks,
Jeff

How about correcting the needed gcc version in Documentation/Changes?

Linux, with up to date documention??  In your dreams perhaps.

BTW.  The above attitude was fostered by informing the Changes
maintainer that the recommended NFS userspace server was on the
exploits list (back in the 2.0 kernel days when knfs was new) and
getting a "I don't use that, so what" response.

...and the documentation continued to recommend an exploitable NFS
server... in short: you must cross-check to be sure, at least in linux
you have a few more options.

With the __builtin_expect patch junio@siamese.dhis.twinsun.com posted, both
2.4.4-pre6 and 2.4.3-ac12 compile with egcs-2.91.66.  Also, 2.4.3-ac13 builds
without any further patches needed.
