Re: [Xen-devel] mini-os: gnttab.c does not compile

MiniOS wasn't declaring a __XEN_INTERFACE_VERSION__, so it broke after the recent dom0_ops.h change.

I pushed a small Makefile fix so it declares it as 0x00030203 (the version right before those changes) and builds again. Someone should also update it to sync with the new header files as well so that the interface version can bumped to the latest.

sorry to bother you with this: while trying to compile mini-os from
xen-unstable.hg, I noticed that compilation failed like this:

gcc -fno-builtin -Wall -Werror -Wredundant-decls -Wno-format
-Wstrict-prototypes -Wnested-externs -Wpointer-arith -Winline -m32
-march=i686 -g -Iinclude -Iinclude/x86 -Iinclude/x86/x86_32 - c gnttab.c
-o gnttab.o
gnttab.c: In Funktion »init_gnttab«:
gnttab.c:165: error: request for member `p' in something not a structure or
make: *** [gnttab.o] Error 1

Looking at the source code, I'm not surprised that this happens, and I suspect
that the file of the same name (gnttab.c) found in
linux-2.6-xen-sparse/drivers/xen/core will also fail to compile (though I
have not checked this).

It seems that the grant-table functions are currently in a non- functional state and that mini-os does not use these functions anyway (except for a call to the init function): After commenting out this call, I was able to build
the mini-os binary.

Is there a particular reason for this? Can I expect the mini-os to work after
removing gnttab.c?

Kind Regards
