Description Doug Semler 2010-04-13 20:19:06 UTC 
When building a compiler with --prefix=/some/dir and --exec-prefix=/some/dir/subdir, the installed gnat cannot find the installed libraries in /some/dir/subdir/lib/gcc/...

I believe that sdefault.adb should be generated with 

S0 : constant String := \"$(exec_prefix)/\";"
not
S0 : constant String := \"$(prefix)/\";"

in gcc/ada/Make-generated.in - when I modify as above, the installed gnat is able to find the installed adainclude and adalib correctly.  (And the problem doesn't occur in the build tree, so the issue isn't apparent until the installed toolset is used).

This is a duplicate of http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38493
Comment 2 Markus Schöpflin 2010-04-15 07:21:57 UTC 
Looks like both are duplicates of http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15819. Back then it has been noted that it's just not supported.
Comment 3 Doug Semler 2010-04-15 12:53:53 UTC 
You're right.  When I searched for it, it reported no bugs found (sigh).

And I see my solution is exactly the same as 38493.
