Linking Error when using Ada.Numerics.Generic_Real_Arrays package

Linking Error when using Ada.Numerics.Generic_Real_Arrays package

[AAFellow]

Hello,

I am writing a program that uses the Ada.Numerics.Generic_Real_Arrays
package.  I use the Real_Vector data type, as well as the *
(vector*vector as well as scalar*vector) , +,  and - functions.

Upon linking, I get errors in System.Generic_Real_BLAS and
System.Generic_Real_LAPACK packages.   In the first file, I am getting
undefined references to sdot_, sgemm_, sgemv_, and snrm2_.  In the
second file, I am getting errors for undefined references to sgetrf_,
sgetri_, sgetrs_, sorgtr_, ssteqr_, ssterf_, and ssytrd_.

I am using GNAT Pro 6.0.1.  Does the compiler not support the use of
the Ada.Numerics.Generic_Real_Arrays package?  Is there anything that
can be done to make this work?

Thanks!!

If you have GNAT Pro, you should have a support agreement with AdaCore. Why not 
ask them?

Right.

Just for the record: I also have GNAT Pro 6.0.1 - it's missing the
library libgnalasup.a which is not included by mistake. Just get it
from AdaCore and place it in the standard library directory (the
command "gnatls -v" shows this under the heading "Object Search
Path"); you also need the linker options "-lgnalasup -lm".

(GNAT Pro 6.1.1. has it.)

GNAT Pro may have been obtained originally from AdaCore, but can be
redistributed to others (who may not have a support contract).
Or isn't GNAT Pro GPL anymore?
