Hi everyone,

I tinik that the cause of previous reported Segmentation fault
error entered in my mind.
So I should relate it to you.

--previous reported Segmentation fault

When I build RedBoot,I discovered that if I
include cdl_option CYGFUN_LIBC_STRING_BSD_FUNCS's
next line
        implements    CYGINT_ISO_STRING_BSD_FUNCS
I was encountered next errors.

There appeared Resolve Conflicts
CYGINT_ISO_STRING_BSD_FUNCS Unsatisfied Requires 
1>=CYGINT_ISO_STRING_BSD_FUNCS
and,
Proposed solution:
CYGFUN_LIBC_TIME_POSIX              Disabled
CYGIMP_LIBC_TIME_ASCTIME_R_INLINE   Disabled
CYGIMP_LIBC_TIME_CTIME_R_INLINE     Disabled
CYGIMP_LIBC_TIME_GMTIME_R_INLINE    Disabled
CYGIMP_LIBC_TIME_LOCALTIME_R_INLINE Disabled
CYGFUN_LIBC_STRING_BSD_FUNCS        Disabled
but I couldn't understand these so I relied auto amendment.

I couldn't resolve this error
so I cheated myself and commented that line.

Now I think this is my original sin.
I think it may resolve by editing CDL files.

Or as Andrew suggests,
this is also eCos version problem ?
