Rene:

  AFAIK porting BB to Linux was abandoned long ago due to the complexity
of the OS interface. It is possible to run BB on Linux/i386 under Wine.

I am speculating that Linz Oberon V4 might be a better gamble. First, the
interface of the Oberon System running as the user-mode app under Linux is
relatively simpler than the BB interface to Windows. Second, the entire
Linux is available in source. You can not only perform system calls from
the Oberon System, but you can also examine what exactly is being called
at the other side. I am not suggesting it is simple, but at least it is
doable.

The Oberon V4 compiler has roots similar to the BB compiler. The two are
close cousins. Unlike the BB compiler, several code generators for
different processors exist for the Oberon System compiler. Perhaps one of
these can be adopted to Raspberry pi.

The remaining and difficult part would be the GUI that must run natively
on the raspberry. The Linux/Unix Oberon System family ran under X11. I do
not know what GUI is being used under Raspberry, so this is to be
investigated. I can only suggest that Nano-X is a common choice for
embedded systems. It used to be called Microwindows, but now it named
Nano-X to avoid litigation. http://www.microwindows.org/

It so happens that I am subscribed to the Nano-X mailing list and I can
attest that Greg Haerr is supporting it very well. It is quite possible
that the Raspberry port either exists, but I am not an expert on this.

Others in this list may add to my GUI suggestions. As a final remark, you
may consider the Linux port of Oberon System 3 rather than V4. It is my
understanding that V4 is simpler than S3, so it is probably a safer bet to
start with.

Hope it helps,
Wojtek

Hi there,

my (almost) 13 year old son will get a Raspberry Pi vor his birthday end
of July. As he is a Linux/Rapsberry beginner, we will start out with
Raspbian as operating system.

Also, he is now starting his "programmer carreer" with CP/BB as his first
language and framework.

AFAIK there was once some work done to port Linux BB to Linux. Does anyone
know what
the current status is?

If it is currently not usable, what O2/CP compilers/frameworks are there
on Linux?

Any input would be appreciated.
Rene
