So that's in the GNAT package. I did not look here, and looked at the  =

libgnat-4.6 package instead.

Here is about what I did:

     $ dpkg-query --listfiles libgnat-4.6 | grep libgnat

     /usr/share/lintian/overrides/libgnat-4.6
     /usr/lib/i386-linux-gnu/libgnat-4.6.so.1
     /usr/share/doc/libgnat-4.6

Thus I did not find it.

Using a command similar to the one I used, here is what you did:

     $ dpkg-query --listfiles gnat-4.6 | grep libgnat

     /usr/lib/gcc/i686-linux-gnu/4.6/rts-native/adalib/libgnat.a
     /usr/lib/gcc/i686-linux-gnu/4.6/rts-native/adalib/libgnat.so
     /usr/lib/i386-linux-gnu/libgnat.so
     /usr/lib/i386-linux-gnu/libgnat-4.6.so

And here the *both* a shared and static version appears.

Something I don't understand now then, is: if the GNAT package provides =
 =

the library, what is the purpose of this separate shared library package=
?  =

I though it may be a dependency package (without installing GNAT) for  =

applications linked to the shared GNAT library, but if I try to remove i=
t,  =

Synaptic tells me I have to remove GNAT as a whole too. Strange=E2=80=A6=


I could build adding this to the Linker package option in the GPR file:

     Common_Switches :=3D
       ([=E2=80=A6],
        "/usr/lib/gcc/i686-linux-gnu/4.6/rts-native/adalib/libgnat.a");


That works, but I don't understand the rational behind this, and I don't=
  =

like it (to not understand it). I will need to have a deeper review of  =

this topic.
