Thanks a lot. On compilation I get:
1. package body IMSL is
2. procedure Free (
3. Ptr : System.Address);
|
>>> "System" is not visible
>>> non-visible declaration at system.ads:40
4. pragma Import (C, Free, "free");
5.
6. function F_Eig_Gen (
7. Matrix : Float_Matrix)
8. return Complex_Array is
9. begin
10. if Matrix'Length (1) /= Matrix'Length (2) then
11. raise Constraint_Error;
12. end if;
13. declare -- No idea, how they report convergence/accuracy
errors
14. function Internal (
|
>>> missing body for "Internal"
15. N : Int;
16. A : Address;
|
>>> "Address" is not visible (more references follow)
>>> non-visible declaration at system.ads:67
17. Terminator : Address := Null_Address)
|
>>> "Null_Address" is not visible
>>> non-visible declaration at system.ads:69
18. return Address;
19. pragma Import (C, Internal, "imsl_f_eig_gen");
20. Ptr : Address :=
Internal (Matrix'Length
21. (1), Matrix (Matrix'First (1), Matrix'First
(2))'Address);
22. Data : Complex_Array (1 .. Matrix'Length (1));
23. for Data'Address use Ptr;
24. pragma Import (Ada, Data);
25. Result : Complex_Array := Data; -- Copy, we
don't own that memory
26. begin
27. Free (Ptr);
28. return Result;
29. end;
30. end F_Eig_Gen;
31. end IMSL;
Compiling: c:/docume~1/testing/imsl.ads (source file time stamp:
2010-07-25 14:00:52)
1. with Interfaces.C;
2. use Interfaces.C;
3. package IMSL is
4. type Float_Matrix is -- Row-wise, packed/aligned
5. array (Positive range <>, Positive range <>) of C_Float;
6. pragma Convention (C, Float_Matrix);
7. type F_Complex is
8. record
9. Re : C_Float;
10. Im : C_Float;
11. end record;
12. pragma Convention (C, F_Complex);
13. type Complex_Array is array (Positive range <>) of
F_Complex;
14. pragma Convention (C, Complex_Array);
15.
16. function F_Eig_Gen (
17. Matrix : Float_Matrix)
18. return Complex_Array;
19. end IMSL;
31 lines: 7 errors
And what do I need on the C side?
Thanks
YC
