L4RE compile error in file rt_sched-proto.h

[Wei Jin]

Hi all!

I got several errors while compiling L4RE(r59). It's about real-time
scheduling extension headers in L4RE(file 'pkg/l4sys/ARCH-x86/rt_sched.h',
'pkg/l4sys/ARCH-x86/rt_sched-proto.h').

Here's the mesage:

In file included from
/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched.h:29:0,
                 from
/home/soap/project/L4/l4/pkg/rtdemo/server/src/rtdemo.c:13:

/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:30:29:
fatal error: l4/sys/syscalls.h: No such file or directory

I can't find any header named "syscalls.h" in pkg/l4sys, so I comment it.


Then I got more errors:

In file included from
/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched.h:29:0,
                 from
/home/soap/project/L4/l4/pkg/rtdemo/server/src/rtdemo.c:13:
/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:57:5:

/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:79:16:

/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:105:19:

/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:127:31:
error: unknown type name ‘l4_threadid_t’


I can't find the definition of 'l4_low_high_t' and 'l4_threadid_t' in L4RE,
but instead I found them in the legacy l4env:

typedef struct {
    l4_umword_t low;
    l4_umword_t high;
} l4_low_high_t;

tyoedef union {
    l4_uint32_t raw;
    l4_threadid_struct_t id;
} l4_threadid_t;

Should I define them the same as l4env?

The declairation 'L4_INLINE int l4_rt_add_time slice(l4_threadid_t dest,
int prio, int time)", which also appears in the online doc(
http://os.inf.tu-dresden.de/L4Re/doc/group__api__calls__rt__sched.html),
seems strange.
Is it a typo? "l4_rt_add_time_slice" seems reasonable.


I'm not sure whether these are proper ways to fix so I need some help.
Any advice would be appreciated.
