problem about compiling EPICS base on Int el XScale RISC CPU and Monta Vista Linux

["marco_hair" <marco_hair@163.com>]

hi,all:

 

  I am trying to compile EPICS base on our new device. It has a Intel XScale IXP-422 266Mhz RISC CPU and Monta Vista linux as embedded OS. Gcc cross compiler is like this:
mxscaleb-gcc (GCC) 3.3.2

I defined a new target archiecture as linux-ixp422. When I tried to compile the target, I got the following message:

we can see the first error message is SIG_SETMASK is not defined. Usually, it's defined in the signal.h file. If I search "/usr/local/mxscaled", where development environment is resident, I can find
./armv5b-linux/include/asm-arm/signal.h                                                               
./armv5b-linux/include/linux/signal.h                                                                 
./armv5b-linux/include/signal.h                                                                       
./armv5b-linux/include/sys/signal.h                                                                   

but, ./armv5b-linux/include/signal.h does not define SIG_SETMASK，
while, ./armv5b-linux/include/asm-arm/signal.h includes the definition of IG_SETMASK marco。
so my first question is: which include directory should I include in my EPICS Makefile?

the second problem, there is another error message is like“storage size of `delayTime' isn't known”，In the osdThread.c, delayTime is defined as following:
struct timespec delayTime;
the "struct timespec" should be defined in time.h，similarly，I can find several time.h，as these:
./armv5b-linux/include/asm-arm/arch-ixp425/time.h                                                     
./armv5b-linux/include/bits/time.h                                                                    
./armv5b-linux/include/dns/time.h                                                                     
./armv5b-linux/include/isc/time.h                                                                     
./armv5b-linux/include/linux/time.h                                                                   
./armv5b-linux/include/linux/xfs_support/time.h                                                       
./armv5b-linux/include/sys/time.h                                                                     
./armv5b-linux/include/time.h                                                                         

In "/usr/local/mxscaleb/armv5b-linux/include/time.h"，there is lines like this：
#if !defined __timespec_defined && \                                                                  
((defined _TIME_H && defined __USE_POSIX199309) || defined __need_timespec)                       
# define __timespec_defined     1                                                                     
                                                                                                      
/* POSIX.1b structure for a time value.  This is like a `struct timeval' but                          
   has nanoseconds instead of microseconds.  */                                                       
struct timespec                                                                                       
  {                                                                                                   
    __time_t tv_sec;            /* Seconds.  */                                                       
    long int tv_nsec;           /* Nanoseconds.  */                                                   
  };                                                                                                  
                                                                                                      
#endif /* timespec not defined and <time.h> or need timespec.  */                                     
#undef  __need_timespec                                                                               
while I should have included this time.h when I compiled the target, so maybe I should define some marco to make those lines work. Does anybody have some experence with this? otherwise I have to check the marco like "__USE_POSIX199309" or "__need_timespec" one by one.

I appreciate for any suggestion and help, thanks a lot in advance.
