[omniORB] omniidl does not generate code - I'm mystified...

[Frank Goenninger]

Hello all,

being a bloody beginner I am trying to get omniidl to generate code  
from the following IDL file:

-X-X-X-

#ifndef __FLEXIO__
#define __FLEXIO__

#pragma prefix "flexio.goenninger.net"

module FlexIO
{
   typedef long            rc_t;
   typedef unsigned long   operation_t;
   typedef unsigned long   data_t;
   typedef unsigned long * data_ptr;
   typedef unsigned long   device_id_t;

   interface LowLevelIO
   {
     rc_t select_device( in device_id_t device_id );

     rc_t read( in  operation_t operation,
                in  data_t      data1,
                in  data_t      data2,
                out data_ptr    rtn );

     rc_t write( in  operation_t operation,
                 in  data_t      data1,
                 in  data_t      data2 );
   };
};

#endif

-X-X-X-

omniidl gets called like this:

$ omniidl -bcxx flexio.idl

Results are:

flexio.hh:

... with flexioSK.cc being similarly empty ...

What am I doing wrong ?? Any hint really appreciated.

Environment:
OmniORB 4.1.4, Mac OS X 10.5.8

Oh, and yes, the Echo example runs just fine !!!

Thanks again -

   Frank
