[uml-devel] No rule to make target `arch/um/os-Linux/sys-i386/registers.c'

[uml-devel] No rule to make target `arch/um/os-Linux/sys-i386/registers.c'

[Robbie Dinn]

Hi,

I have just been building linux-2.6.9-rc2-mm4 + incremental patches
from http://user-mode-linux.sourceforge.net/patches.html downloaded
fresh today.

I think the i386 UML target is broken.

I got a build error when doing make:

robbie@linux-uml:~/linux-2.6.9-rc2-mm4-um> make ARCH=um linux
[snip]
   LD      arch/um/os-Linux/drivers/tuntap.o
   LD      arch/um/os-Linux/drivers/built-in.o
make[2]: *** No rule to make target 
`arch/um/os-Linux/sys-i386/registers.c', needed by 
`arch/um/os-Linux/sys-i386/registers.o'.  Stop.
make[1]: *** [arch/um/os-Linux/sys-i386] Error 2
make: *** [arch/um/os-Linux] Error 2
robbie@linux-uml:~/linux-2.6.9-rc2-mm4-um>

I couldn't find arch/um/os-Linux/sys-i386/registers.c
but I looked in arch/um/os-Linux/sys-x86_64 and found a
one there.

I did

cp arch/um/os-Linux/sys-i386/registers.c 
arch/um/os-Linux/sys-x86_64/registers.c

then recompiled, and it build OK.
The UML kernel even booted too!

Oops, missed a 'quilt add'.  It's fixed now.

Presumably you copied in the other direction.

Anyway, that's what would be called an unsupported configuration :-)
