Which GNAT requires LAPACK and BLAS for Ada.Numerics.xxx?

Which GNAT requires LAPACK and BLAS for Ada.Numerics.xxx?

[Jerry]

The PLplot developers need a bit of help with automating their build
process with regard to Ada (GNAT only). They use cmake. As the person
who wrote the Ada binding, I've been asked to get the information.

Currently, cmake has an Ada 2005 flag which if set, with-s and use-s
Ada.Numerics.Long_Real_Arrays which was added in Ada 2005. If the flag
is not set, the binding source code is automatically modified a little
bit so that the 2005-specific stuff is not needed. (The binding only
needs the Vector and Matrix declarations, so this is a lot of work for
such a small benefit, but that's the way things are right now.)

If Ada.Numerics.Long_Real_Arrays is used, it needs to link to lapack
and blas which the PLplot cmake process can be made to handle.

So the questions are:

(1) What is the earliest version of GNAT that requires lapack and blas
if Ada.Numerics.Long_Real_Arrays is referenced? I think it might be
4.3.

(2) Is there an earlier version that has the limited capabilities
required by the Ada binding, specifically, only the declarations for
type Real_Vector is array (Integer range <>) of Real'Base;
type Real_Matrix is array (Integer range <>, Integer range <>)
but which does not require linking lapack and blas?

Thanks,
Jerry

Definitely in 4.3.4:

$ pwd
/usr/local/ada-4.3/lib/gcc/i686-apple-darwin9/4.3.4/adainclude
$ egrep -iH "with.*blas|with.*lapack" a-*.ad[sb]
a-ngcoar.adb:with System.Generic_Complex_BLAS;
a-ngcoar.adb:with System.Generic_Complex_LAPACK;
a-ngrear.adb:with System.Generic_Real_BLAS;
a-ngrear.adb:with System.Generic_Real_LAPACK;

I started with Martin Dowie's 296 & 346:

IIRC, the changes were minor. If it would help, I have the last, 
independent set that I used before switching to BLAS/LAPACK in June, 
20009.

I'll be very interested to see PLplot working well with GNAT Ada.
Cmake needs a C compiler also and I have not been successful with
camke nor with PLplot for Windows.

Yes, it is 4.3.

GCC 4.2, I think.

PLplot does work well with GNAT, and yes, as I noted here a few days
ago in another thread, installation is challenging. I wish there were
binaries but as far as I know there are none. I'm not sure why,
probably because the development team works hard to accommodate so
many platforms and do remarkably well in that regard.

Please put all your PLplot questions to the list at

https://lists.sourceforge.net/lists/listinfo/plplot-general

Debian does have binary packages:
