Building OKL4 "Hello World" Server

[Lutz Schönemann]

I've read many things about how Iguana works and now I want to build  
my first OKL4 Server. I followed every step described in the following  
Wiki-Entry:
http://wiki.ok-labs.com/DevelopAServer
but the Hello World Server doesn't get compiled. Now errors or warnings.
I'm also new to SCons and IDL4. Is there any additional step that  
should be done to get this problem solved? Is IDL4 automatically  
called when running tools/build.py?

Thanks for help
Lutz

Problem solved. The mistake was that I've appended the Hello World  
related script at the end of the global SConscript. After moving the  
code above the "Linux" script it gets compiled.

But is there a documentation about IDL4? Something that tells me what  
files are created and what exactly IDL4 does?

You can search for the Idl4 manual.

Mr Schonermann

 

In response to your recent post on IDL4 below is the link to the current IDL4 manual from the OKL4 Labs website.

 

IDL4 Manual (Acrobat PDF)

 

There is even more information available at the OKL4 website

 

IDL4 Projects at OKL4

 

IDL4 is an interface language like CORBA and DCE and since its last format release in 2003 is currently under review for a new release.

You can find the Beta on the website.

 

Should you need a tutorial as a starting point, let me recommend you follow these web links:

 

Introduction to CORBA by Sun

 

While this reference is Java centric is has a great deal of conceptual information

 

A more specific tutorial on CORBA for Linux and C/C++ can be found at the link below

 

 

CORBA C++/C Language Tutorial

IDL4 is, from what I got so far, a subset of the CORBA IDL, which
defines interfaces between servers and clients. This IDL is used by
an IDL compiler ("magpie") to generate the server and the client
skeleton and stub code, respectively. This code does nothing else
than piping your calls through OKL4 IPCs. In addition, you get handed
the server loop function, which waits for incoming calls and deploys
them to the respective "business" code.

All in all, up to 3 files are generated (at least in OKL4 2.1):
Two files (one .h and one .c) for the server side (declarations and
the server loop code), and one file (.h) for the client side. I dunno
about the server side files; the client side include file is only
generated if it's actually used somewhere (i.e. by having an
#include <interfaces/...> in your client code).

The IDL provides a couple "annotations" to interfaces, enclosed in
brackets "[....]", like an uuid() to differ between interfaces if
multiple have been specified, or the presence of an async or
exception handler.

A thing which seemingly doesn't work is defining data structures
(maybe someone can correct me on that one); you will have to use
#include-s of header files if you want to other than the default
data types.

Lutz - great that you solved your problem.  I just wanted to point
out that OKL4 3.0 has been released, which comes with an SDK which
should avoid problems related to modifying the OKL4 build system
internals.  The SDK should allow people to use their own build
system and offers greater flexibility in building systems
on OKL4.

Is there also a SDK version for x86 architecture? Or how can I create  
one out of the sources?

Lutz - Unfortunately the OKL4 SDK is currently only available for ARM-based
processors.

(I realized that you are developing on x86-based processors at the moment,
but wasn't sure whether that was only for quick prototyping or not.)
