   There currently doesn't seem to exist any 'libc' like thing for programs which 
   are going to be run under gdb's simulator to link against (distributed with 
   gdb).  It seems to be that using newlib would be the obvious candidate, and 
   I'll return to you any improvements that I make.

   I have looked at the newlib distribution and it seems that I'd need to add 
   into libgloss/ the "os" stuff necessary for basic reading and writing through 
   the gdb simulator.

   Currently libgloss/ doesn't support the Arm at all so I will have some config 
   hacking to do.

Actually, newlib has the necessary syscall stuff for arm programs to run
on the ARMulator.
[It use to be the case that this stuff lived in newlib.  Then, libgloss
was created to hold this stuff, but the arm port of newlib hasn't been
updated.]

Doug,

Indeed, I'm now building it and it seems to be going OK. Earlier the

*** This configuration is not supported in the following subdirectories:
     target-libgloss
    (Any other directories should still work fine.)

warning, plus another hidden problem were making me think otherwise.

Thanks,

Richard.
