Description of Problem:
compile of kernel 2.4.17 fails at network.o

Version-Release number of selected component (if applicable):


How Reproducible:


Steps to Reproduce:
1. make bzImage
2. 
3. 

Actual Results:


Expected Results:


Additional Information:
The 2.4.17 kernel DOES build on gcc-3.0.3, without the kernel patch below.

Here are some notes from lkml:

In mailing-lists.linux-kernel, you wrote:

 I've seen this problem while trying to compile recent kernels with
 RedHat Rawhide's gcc-3.10-0.1, are you using that?

 I traced the problem to a conflict in include/linux/sunrpc/clnt.h.  It
 declares rpciod_tcp_dispatcher as extern, but it also includes
 linux/sunrpc/xprt.h, which has a static inline definition of
 rpciod_tcp_dispatcher.  Previous versions of gcc seem to choose the
 static inline definition, while gcc-3.10-0.1 chooses the extern
 declaration.  So I simply deleted the extern declaration from
 linux/sunrpc/clnt.h.

 With this change, the kernel compiles but oopses in do_signal()
 shortly after booting.  jakub logged a similar conflict in
 RedHat Bugzilla 57413, which I paraphrase here:  do_signal() is
 delcared as asmlinkage int FASTCALL in arch/i386/kernel/signal.c, but
 asmlinkage gives the attribute regparm(0), while FASTCALL gives the
 attribute regparm(3).  Again, prior versions of gcc chose regparm(3),
 while gcc-3.1-0.10 chooses regparm(0).  So I simply deleted the
 asmlinkage declaration.

 With these two small changes, kernel 2.4.17 compiles with gcc-3.1-0.10
 and boots on my i386 machine OK.  In fact, I'm writing this under it
 now.  However:

 [whitney@pizza linux-2.4.17-gcc-3.1-0.10]$ grep -r "asmlinkage.*FASTCALL"
.
 ./arch/i386/kernel/vm86.c:asmlinkage struct pt_regs *
 FASTCALL(save_v86_state(struct kernel_vm86_regs * regs));
 ./arch/s390/kernel/signal.c:asmlinkage int FASTCALL(do_signal(struct
pt_regs
 *regs, sigset_t *oldset));
 ./arch/s390x/kernel/signal.c:asmlinkage int FASTCALL(do_signal(struct
pt_regs
 *regs, sigset_t *oldset));
 ./arch/s390x/kernel/signal32.c:asmlinkage int FASTCALL(do_signal(struct
pt_regs
 *regs, sigset_t *oldset));

 Maybe some of these need cleaning up?  I'll have to leave that to the
 experts, I'm more of a grease monkey.

 Cheers,
 Wayne

Comment 1 Jakub Jelinek 2001-12-28 12:01:46 UTC
As for rpciod_tcp_dispatcher, this is going to be fixed in gcc 3.1-0.11,
the other one is kernel problem which will be fixed at least in 2.5.2 and
hopefully 2.4.18 too.
