gnat executables

Whenever I compile some code for a different PC , it asks me for the
runtime libraries for gtk and some others. Is there a way I can link
my executable so the functions used in these libraries are included in
my executable ?

You have to link to the static (object) libraries. Whether this would work
depends on whether the provider of the library allows static linkage or
not. The answer would depend on the target platform and the licensing
policy.

The librarys are all debian based, things like libgnadecommon and
libgtk,
I was really looking for the command to give to gnatmake, I know -
static option links
in the gnat runtime etc

If I understand you correctly you have two options:

1. Instead of -lfoo specify /full/path/to/libfoo.a

2. Something like: -largs -Wl,-Bstatic -lfoo -lbar -Wl,-Bdynamic

The latter will switch the linker to static mode, link in the libraries
you specify and then switch it back to dynamic linking for the rest of
the command line (i.e. the part that gets added automatically for the
GNAT runtime etc).

Note also that the latter will probably only work on systems that have
the GNU linker and you may have to replace -Bstatic and -Bdynamic by
something else on other (i.e. non-Linux) OSes.

additionally, specifically regarding gtkada, there should be gtkada-config
script installed, which spits switches for the linker and compiler. To be
used like:

$ gnatmake ... -largs `gtkada-config --libs --static` ...

See gtkada-config --help

There's an example Makefile here:

I don't think AdaCore are 100% consistent on this, but they have used
an environment variable LIBRARY_TYPE to control GPRs: for example, (one
of mine),

project BC is

type Library_T is ("static", "relocatable");
Library_Type : Library_T := external ("LIBRARY_TYPE", "static");

for Library_Name use "bc";
for Library_Kind use Library_Type;
for Library_Dir use "../../lib/bc/lib-" & Library_Type;
for Externally_Built use "true";
for Source_Dirs use ("../../include/bc/");

end BC;

I assume you are using GtkAda on Windows.
GTKAda requires several DLL for the C libraries GLib, Pango, Cairo, ATK,
etc .. found in directory GTKADA\bin
( libgtk-win32-2.0-0.dll, libgdk-win32-2.0-0.dll ..)

You have to ship these DLLs with the application (about 10 Mega)
The switch in scenario (static, relocatable) applies only to the Ada
part i.e. the Gnat Run-Time and GTKAda.
these DLLs are libgtkada-2.18.dll and libgnat-2011.dll

If you build with static you have the Ada run-time and GTKADa
in the executable (which explains the size of at least 1 Mo)
With relocatable you must ship also the corresponding DLLs for Ada.

Thanks for the help from you all here.
