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: error: unknown type name ‘l4_low_high_t’
/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:79:16: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘slice’
/home/soap/project/L4-Build/x86/l4re/include/x86/l4/sys/rt_sched-proto.h:105:19: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘slice’
/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.
