OpenGL and SDL

OpenGL and SDL

[Joseph Montanez]

I was hoping to have those two running with Ada, however Ada Open GL
and Ada SDL are using gnat4.1. Resulting in:

gcc: error trying to exec 'gnat1': execvp: No such file or directory

I am pulling the Repositories from github:
https://github.com/io7m/coreland-sdl-ada
https://github.com/io7m/coreland-opengl-ada

Do I have to use older versions of gnat to use these libraries?

I've tried Header translation too, but I get
cc1: error: unrecognized command line option "-fdump-ada-spec"

On what platform and what compiler (version of gnat) ?

This generally means that you don't have gnat installed with the used 
gcc. What the output for:

    $ which gcc
    $ which gnatmake

Pascal.

And can you compile:

$ cat dummy.adb
procedure Dummy is
begin
    null;
end Dummy;

$ gnatmake dummy

If not then the Ada compiler seems broken on your computer. BTW, what 
the output for:

$ find /usr -name "gnat1"

Pascal.

Using the Debian packages then.  I have a hunch but you'll need to give
full details to be sure.  So what is the *exact* output of:

#!/bin/sh
dpkg -l "gcc*" "gnat*" | grep ^i
ls -lF $(which gcc)
ls -lF $(which gnatgcc)
cd coreland-sdl-ada; make
cd coreland-sdl-ada; make CC=gnatgcc  # <- that's my hunch

Never guys I got it! Adding CC=gnatgcc did nothing but I ended up conf-
adacomp and it worked fine!

SDL Ada
 * I edited conf-adacomp to be "gnatgcc" instead of "gcc"

OpenGL Ada
 * I edited conf-adacomp to be "gnatgcc" instead of "gcc"

That's the problem I suspected. GCC is pointing to version 4.5 whereas 
your Ada compiler is version 4.4.

Pascal.
