Standalone (.exe) Ada Programs can run in isolation of any ada compiler - True or False ?

[Austin Obyrne]

1)Would some reader confirm that this true or false and explain the mechanics of how it is done.

2)Is the ensuing (.exe) program then bound to that computer alone i.e. customised for running in that environment only and will require customising again to any other computer i.e. not generally portable without some attention each time.

I assume this is homework. If we answer you would lose the experience of learning. I care about my fellow man too much to do this to you.

Is it really true that you don't know that the output of the compilation process
is an executable file containing machine language instructions, and that this
is an .exe file in the windows environment?

What do you think the ada compiler is? Or your IDE program?

For how long have you been using computers? Has it not occurred to you
to find out what all those extra files in your work folder are?

This may help explain why you think editing Ada source is a user interface.

No. This is a sci.crypt (very) frequent poster who knows a lot less than
he claims.

This isn't homework, this is a decade+ of misconception where the first
glimmers of understanding are starting to show.

The Ada compiler translates the source code into object code, which is
linked against Ada libraries (which come with the compiler) and system
libraries to produce the executable.

After this point, the source code and the object code are no longer
relevant.

The Ada libraries and the system libraries are usually dynamic libraries
(.dll on Windows), which means that they are separate entities. When you
run the .exe, the system first loads the .exe and then loads all the
.dlls which it needs (and the ones they need, ...); then the system can
actually run the program.

You don't need to worry about the system libraries, but the Ada
libraries won't be present on machines that haven't had Ada installed;
and they must match the .exe, so you can't mix a GNAT GPL 2014 .exe
with a GNAT GPL 2013 .dll.

The simple way round this is to supply the .exe and the (Ada) .dlls it
needs in one directory.

On my machine, the .dlls are libgnat-2014.dll and libgnarl-2014.dll,
both in C:\GNAT\2014\lib\gcc\i686-pc-mingw32\4.7.4\adalib (together with
a *lot* of other files!)

And, of course, this is Windows; you can't run the same .exe on Linux or
Mac.

Many ,many thanks Simon - this is the advice I needed - I have no pretentions to being an Ada developer or indeed anything more than a hardworking problem solver on the back of a very successful career running ships.

In the contrary, this person has displayed strong hostility to clue in the
past.

He is NOT taking a course, and has claimed or implied computer ability
well beyond his demonstrated capacity for over a decade.

A few examples of OS / compiler combinations where the .exe can be built to be standalone, that is the .exe can run on another machine that never saw any Ada tool:

 - Windows / GNAT GPL (including Windows GUI stuff)
 - Windows / MinGW (including Windows GUI stuff)
 - Windows / ObjectAda (at least command-line tools)
 - Ubuntu Linux / the GNAT version provided by default

I wish you luck in finding a problem that is within your capacity to 
solve, to date it appears that you have failed to do so.

Actually, for all I know OP is still running GNAT 3.15p (he was, up to a
few months ago); no idea whether that used static or dynamic libraries
by default.

It's not always as simple as it might be to force static linking.

Or link statically; that seems to be a skill that has been lost?

There are/used to be a few glitches linking glibc statically on
GNU/Linux due to some networking routines that are not/were not
included in it (gethost* etc IIRC). I do not know whether or not
this applies to static linking in a GNAT-on-Windows environment.

That's an outright lie.

The way you've recently insulted people who've been really trying to help
(just not the sort of help you wanted to hear), and the sheer arrogance with
which you dismissed them tell of *GREAT* pretensions.

Static linking of the GNAT run-time library on GNAT public/GPL for Windows is the default since I'm using it - I think, version 3.13p around 2000. I even don't know which option you would need to get the dynamic RTL linking and just discovered with your post it was possible on Windows!
