Thanks. Now, imsl.ad(b,s) compile fine. Now to make the code work:

Do I need to have a C file also? The IMSL library won't activate by
itself.

I have a main file in Ada as testmatrix.adb:

with Imsl;
use Imsl;

procedure TestMatrix is

   Values : Complex_Array :=3D F_Eig_Gen (((8.0, 1.0, 5.0), (4.0, 4.0,
2.0), (18.0, 5.0, 7.0)));

begin
   null;

end TestMatrix;

So I compile

gnatmake -c imsl.adb
gnatmake -c testmatrix.adb


And then work on the .ali files

gnatbind -n imsl.ali testmatrix.ali

I'll need a C file to do the linking. What to put in the C file?

Do you mean renaming the procedure imsl.adb to Internal
imsl_f_eig_gen.adb . Sorry this part is not clear to me.

Thanks
