Re: Can't compile generated code

[Bowie Owens <bowie owens csiro au>]

Hi Johan,

The C++ output depends on the generated C output. So you need to run 
orbit-idl-2 without the -lcpp as well. In general if you have a IDL file 
X.idl you generate the following files with orbit-idl-2 X.idl:

X.h
X-common.c
X-skels.c
X-stubs.c

Then you generate with orbit-idl-2 -lcpp X.idl:
X-cpp-common.cc X-cpp-common.h
X-cpp-skels.cc X-cpp-skels.h
X-cpp-stubs.cc X-cpp-stubs.h
X-cpp.cc X-cpp.h

You will need to compile each of the C files with the C compiler. You 
will need compile X-cpp.cc with the C++ compiler (you don't need to 
compile the others directly since they are #include'd by X-cpp.cc). You 
then have to link the object code with your own code to produce a client 
and/or server.
       

Also, you will have to put your types/interfaces/... into a module as 
the C output can conflict with the C++ (struct TimeOfDay will be mapped 
into struct TimeOfDay in the C output as well as the C++ output).
