Re: Interfacing Ada with C

[Ada novice <posts@gmx.us>]

Success here with the testing! Thanks for all your very kind help
Simon. First, I would like to draw your attention on 1 point. At
first, I was copying your raw files into AdaGIDE in order to save
them. Then running gnatmake -p -P test_extensions did produce a lots
of error messages: incorrect line terminator. I remember getting this
message before and what I did was to save the files in GPS and the
error messages disappear. I think in AdaGIDE pasting raw text can
cause some incompatibility due to the file system used. This is why I
guess I got this error: incorrect line terminator. I can't explain
this but I don't have it in GPS.


After successfully saving all your raw files within GPS, I ran
gnatmake -p -P test_extensions without any warnings/error messages and
the following were created:

A.) A lib folder is created at the same hierarchy level as src and
test. It has 2 files:
1.libada_math.dll
2.ada-numerics-generic_complex_arrays-extensions.ali


B.) In the src folder a .build folder is created with 2 files:
1. ada-numerics-generic_complex_arrays-extensions.ali
2. ada-numerics-generic_complex_arrays-extensions.o

C.) In the test folder a .build folder is created with 6 files:
1. b~test_extensions.adb
2. b~test_extensions.ads
3. b~test_extensions.ali
4. b~test_extensions.o
5. test_extensions.ali
6. test_extensions.o

Then I was able to build using Build main: test_extensions.adb
successfully.

Now for the outputs I get:

 2.00000E+00  4.00000E+00
 2.00000E+00 -4.00000E+00
 9.99999E-01  1.10569E-07

-6.00000E+00
-4.00000E+00
-2.00000E+00
-1.21279E-07
 2.00000E+00
 4.00000E+00
 6.00000E+00

 6.00000E+00  0.00000E+00
 4.00000E+00  0.00000E+00
-6.00000E+00  0.00000E+00
 2.00000E+00  0.00000E+00
-3.17504E-07  0.00000E+00
-4.00000E+00  0.00000E+00
-2.00000E+00  0.00000E+00

The second set of results are for the Test16 which are ok. What about
the third set of results? What are these?

Here are the switches for "build main"

%gnatmake -q -c -gnats -u %eL -P%PP %X %fp

which are a bit similar to those you have in the jpg file from your
earlier post.

I didn't add -gnatpg for the compiler switch. I had these: -gnatqQ -
gnat05

and I can compile fine and output the results. Is the -gnatpg a
necessity?


Thanks very much for helping me with the compilation. Now it's good
that some more testing is done on different cases. Do you plan to add
the output for eigenvectors also?
