[omniORB] Beginer's question on omniidl

[Guangyu Gu]

Today I downloaded the omniORB 3.0, and tried to compile
the echo.idl in /src/example/echo.   I am running the
omniORB v3.0 on a x86 machine.

I typed  "omniidl -bcxx echo.idl" as instructed by the
user guide. I noticed that the hh file and cc file contain
no information on the echo interface.

What can I do to get the valid stub files? Thanks.


The echo.idl is a simple file.

#ifndef __ECHO_IDL__
#define __ECHO_IDL__

interface Echo {
  string echoString(in string mesg);
};

#endif



The resulted files are
omnicpp -lang-c++ -undef -D__OMNIIDL__=0x2301 -D__OMNIIDL_CXX__ echo .hh
and
omnicpp -lang-c++ -undef -D__OMNIIDL__=0x2301 -D__OMNIIDL_CXX__ echoSK .cc



Here is the .HH file

// This file is generated by omniidl (C++ backend)- omniORB_3_0. Do not

__omnicpp__lang_c____undef__D____OMNIIDL_____0x2301__D____OMNIIDL__CXX_____echo_hh__

#endif  //

The .CC file is

// This file is generated by omniidl (C++ backend)- omniORB_3_0. Do not 
edit.

#include "omnicpp -lang-c++ -undef -D__OMNIIDL__=0x2301 -D__OMNIIDL_CXX__

static const char* _0RL_library_version = omniORB_3_0;
