Hi all,
I've got a session of user mode linux up and running using the
pre-compiled binaries so thought I would have a go at building my own
uml. Hopefully this will help me to understand uml a bit more. I have
downloaded the 2.6.18 kernel from kernel.org and applied the -mm patch
(Which I believe I was supposed to do). I have made a config file using
make defconfig ARCH=um. Now, when I run make ARCH=um I get the following
error:
In file included from arch/um/kernel/mem.c:8:
include/linux/mm.h: In function ?page_zone_id?:
include/linux/mm.h:450: warning: right shift count >= width of type
arch/um/kernel/mem.c: In function ?paging_init?:
arch/um/kernel/mem.c:229: error: ?ZONE_DMA? undeclared (first use in
this function)
arch/um/kernel/mem.c:229: error: (Each undeclared identifier is reported

arch/um/kernel/mem.c:229: error: for each function it appears in.)
make[1]: *** [arch/um/kernel/mem.o] Error 1
make: *** [arch/um/kernel] Error 2
The full make output is at the end of this mail in case a bit more
output is needed. Now I've obviously missed a step here but I can't
figure out what. Can anyone point me in the right direction please?
Thanks,
Lee
