Hey,
I was trying to compile the 2.6.29 kernel after patching it, as mentioned on quick start page. I am getting these errors:
plan9/syscalls.c: In function ‘sys_plan9_rfork’:
plan9/syscalls.c:362: error: incompatible type for argument 1 of ‘sys_clone’
plan9/syscalls.c:362: error: too few arguments to function ‘sys_clone’
Then I looked up at the clone manual and found this:
" Thus, sys_clone only requires the flags and child_stack arguments, which have the same meaning as for clone()."
and,
"Since Linux 2.5.49 the system call (sys_clone) has five arguments. The two new arguments are parent_tidptr which points to the location (in parent and child memory) where the child thread ID will be written in case CLONE_PARENT_SETTID was specified, and child_tidptr which points to the location (in child memory) where the child thread ID will be written in case CLONE_CHILD_SETTID was specified."
The fifth argument is not specified (only 4), thus I'm confused now, I even tried passing 2 arguments (FLAGS, 0), but it was still showing this error.

sys_clone seems to just take a pt_regs struct these days.
do_fork() still takes the good old fashioned parameters, we might have
to switch and use that, otherwise we'll have to mung the arguments
into registers.
This is all assuming that I actually read the code right, and since
it's 2 am right now, chances of that being true are in peril.

Sorry for such a long paste!
these errors happen while i try to compile **Plan9 binary** as a module.
If i choose to build it in the kernel, no errors again! :)

The system call patches are meant to be built into the kernel, there
is no way to define plan9_syscall_table in a module. As for building
the loader as a module, I'm not quite sure if building it as a module
currently works, but in principle it should.
I'm building everything into the kernel in my tests :)

sys_clone() wants a pointer to a pt_regs struct.

sys_clone here? We're trying to translate Plan 9 flags to Linux

we can't pass the flags we want to sys_clone() anymore.

Are we sure the values in pt_regs are what we want to pass to
sys_clone here? We're trying to translate Plan 9 flags to Linux
flags---I would think that we have to call do_fork() explicitly, since
we can't pass the flags we want to sys_clone() anymore.
Well, do_fork() will be our final candidate, but even this should work. The latest clone() manual says that sys_clone needs 5 arguments, but the function definition says only one. Things are kinda unclear.

The manpages refer to userspace wrappers around the kernel calls,

which are different and take different arguments. Since we're in
kernel space, the userspace wrapper taking 5 arguments means nothing
to us. Plus, the manpages aren't necessarily up to date, anyway.

The clone() man page describes sys_clone() as well. I checked the latest manpages from kernel.org, but quite possible they aren't up to date.
Change plan9/syscalls.c:362 to:
ret = sys_clone(®s);
sys_clone() wants a pointer to a pt_regs struct.
Even this is not working.

I think we should just be using do_fork()

The code compiled just fine before I committed it. In any case, as
others have suggested, we should really be using do_fork() instead.

That was the reason, I used 2 arguments with sys_clone in the initial rfork() patch i submitted.

Yeah right. I'll start with this.
But how can other people compile the kernel?

How could i get through compiling the patched kernel without any errors?
