[okl4-developer] Hello World on arm926ejs (continued) and some questions on temporal partitioning and on POSIX.

[Hugues Balp]

    Thank you Peter for your answer,

I have tried to compile the OKL4_3.0 archive with the command line you 
gave to me
and got the following error:

Executing: licence_tool --type=sdk --mode=expand 
/home/hugues/tools/okl4/okl4_3.0/build/SDK/object/sdk/sdk/okl4
sh: licence_tool: not found
scons: *** licence_tool returned error, perhaps it's not installed?

So I suppose I have to install some kind of license tool and don't know 
how and
what are the underlying conditions...

Thanks in advance,

                Hugues.
