Installing AdaSDL to a Debian system

Installing AdaSDL to a Debian system

[LaeMing Ai]

Hi,

I have GNAT+GPS installed on my Debian/Testing system via apt.

I have AdaSDL sources downloaded to a directory in my user space.

AdaSDL seems to have compiled fine following the included instructions - I have a .../build/gnat/gen/static.release/lib/ folder full of .ali files.

How do I get these into the GNAT build chain?

# sudo make SDL_PLATFORM=linux SDL_BUILD=static SDL_MODE=release DESTDIT=/usr/lib/gcc/x86_64-linux-gnu/6/ install

doesn't appear to work. Nothing shows up in the expected place.

I manually copied the .ali files and libsdlada.a across to 

  /usr/lib/gcc/x86_64-linux-gnu/6/adalib/

and the source .adb and .ads files across to

  /usr/lib/gcc/x86_64-linux-gnu/6/adainclude/

Obviously I have missed something, likely because I ended up trying to do a manual install. Any help appreciated!

you need -largs -lsdl
or a

 package Linker is
     for Default_Switches ("Ada") use ("-lsdl");
 end Linker;

Above should be DESTDIR.

You need to execute sdl2-config --libs in back ticks on nix, I don't know
how you call that in windows, I can't remember.

Thanks for assistance so far.

I ended up getting SDL working in C enough to realise it is still too high level for what I want to achieve anyway. :-/

Moving on to X11ada...

(oh for the days when video was just a block of RAM you had all to yourself! ;-)

Presumably it still is:

Heh. Ironically(?) if I didn't want to keep X11 going to use the GPS IDE during development, I could just take over the raw Linux frame buffer.

You're not making any sense. If C is too high level, WTF are you posting on comp.lang.ada? Ada is a high level language with low level access to things. What I posted was a way to get at the pixel data in 1 and 2 dimensions, that is what you wanted.

SDL is too high level - doesn't seem to support raw pixel manipulation without excessive hoop-jumping.

C is portable machine code. I can write stuff in it when I have to, but am rather keen on using Ada where possible.

Re: Installing AdaSDL to a Debian system

I am now looking into directly writing to the Linux Framebuffer (either on a secondary monitor, on on a second cable into my primary so I can 'channel switch' between the dev environment and my program output).

Re: Installing AdaSDL to a Debian system

[LaeMing Ai]

Turns out what I want is one of these: http://doc.qt.io/qt-4.8/qvfb.html (Though obviously not in QT). I think I can munge a hardware-simulation of one together as per the above post.

Re: Installing AdaSDL to a Debian system

[LaeMing Ai]

I have done some thinking and some redesign and I am determined to have another go at SDL with Ada.

So far:

SDL itself is (AFAIK )installed:

# sdl2-config --libs

returns

-L/usr/lib/x86_64-linux-gnu -lSDL2


I (believe I have successfully) installed sdlada with this command line:

sudo make SDL_PLATFORM=linux SDL_BUILD=static SDL_MODE=release DESTDIR=/usr/lib/x86_64-linux-gnu/ada/adalib/ install

(Note: in the sdlada readme there is a typo: DESTDIR is DESTDIT)

It installs in the expected place: /usr/lib/x86_64-linux-gnu/ada/adalib/sdlada/ contains folders: 'include', 'lib' and 'share' and their contents.

The question now is... What next?

How do I tell GPS to use the installed libraries?
