Re: GNAT for Cross Compilation

"   I am fairly new to GNAT and am interrested in trying to set it up to
cross compile Ada code for a student research project.  Our host machine
is a Sun Sparc (running SunOS4.1.3) and the target is a 68030 board.  I
have gotten GNAT 3.05 up and running on the native SUN (I assume this is
the first step).  However, I have been unable to find any documentation
on how to proceed to set up the cross compiler.  Has anyone out there
done this before, or know where I might look to learn how to do this?"

It is not clear what you mean by "have gotten GNAT 3.05 up and running on
the native SUN". The first step is to be able to do this *from the source
distribution* so that you can indeed build gcc from its sources.

Building a cross-compiler involves quite a bit of tricky fiddling around,
and requires a fair amount of familiarity with gcc and the gnat make file.
We are currently working on improving the cross-compiler build procedures
to make them easier.
