IDL Compiler


MICO IDL

Compiler name : idl /usr/local/bin/idl, /usr/bin/idl.

Option: Example idl --c++-skel --poa --no-boa RTCPackage.idl
It is OK to use normally in C++.

TAO IDL

gperf problem
gperf needs to use gperf attached to TAO. In FreeBSD /usr/bin/gperf (included in the system?) And /usr/local/bin/gperf (TAO included).
By default it uses $ ACE_ROOT/bin/gperf, so you must set the environment variable ACE_ROOT or set the option - g :: <gperf_path>.

TAO_ROOT
If the environment variable TAO_ROOT is not set, IDL provided by TAO can not be read.
In addition, include TAO's ORB IDL (ex. /usr/local/include/tao/orb.idl) 

 #include <orb.idl>
Otherwise, TypeCode etc. can not be used. 
 #ifdef TAO_IDL
 #include <orb.idl>
 #endif
It is necessary to separate it from other IDL compiler as etc.

ORBit2 idl

Compiler name : orbit-idl-2
ORBit is supposed to code in C by default.

Help 

 Usage: orbit-idl-2 [-D|-define STRING] [-I|-include STRING] [--libIDL-version]
        [-v|--version] [-l|--lang STRING] [-d|--debug INT] [--idlwarnlevel=INT]
        [--showcpperrors] [--nostubs] [--noskels] [--nocommon]
        [--noheaders] [--noidata] [-i|--imodule] [--add-imodule]
        [--skeleton-impl] [--backenddir=DIR] [--c-output-formatter=PROGRAM]
        [--onlytop] [--pidl] [--nodefskels] [--deps=FILENAME]
        [--headerguardprefix=STRING] [--output-dir=STRING] [-?|--help]
        [--usage] <IDL files>

Option
  • l or - When you specify cpp with --lang, C++ code is generated. However, since we are using C code, we also need to generate C code. orz ...

 orbit-idl-2 RTCPackage.idl
 orbit-idl-2 -lcpp RTCPackage.idl

In this way, 

 RTCPackage-common.c
 RTCPackage.h
 RTCPackage-cpp-common.cc
 RTCPackage-cpp-common.h
 RTCPackage-cpp-skels.cc
 RTCPackage-cpp-skels.h
 RTCPackage-cpp-stubs.cc
 RTCPackage-cpp-stubs.h
 RTCPackage-cpp.cc
 RTCPackage-cpp.h
Is generated. Since xxx - cpp.cc internally includes all the sources, compile only this source if both skeletons and stubs are needed.

  • Problem of orbit-idl-2 If you put a sequence of Object reference in struct, skeleton compilation does not pass. 
     struct ComponentProfile
 {
    PortProfileList inport_profile_list;
    PortProfileList outport_profile_list;
    ServiceProfileList service_profile_list;
    ServiceProfileList consumer_profile_list;
    RTC parent;
    RTCList children; // × The sequence of typedef Object ref is useless
    sequence<RTC> children; // × Typedef does not matter
    sequence<RTC,100> children; // × No bounded sequence
    sequence<short> children; // ○ If it is not Object ref OK
 };
