 I have found that the following change to gcc/ada/Makefile.in reduces
 but does not solve the problem.  This change consists in atatically
 linking libgnat.so against libiberty.a.  The patch below is done only
 on GNU/Linux on *86, perhaps it should also be done on other
 platforms.  With this change, I only get one undefined symbol and that
 is `convert_addresses'.
 
 It appears to me that old versions of gnat (3.11p being one) used to
 include a copy of binutils that had this function in libaddr2line.a;
 newer versions seem to not include binutils anymore, and the current
 binutils no longer have this library.

 I've managed to bootstrap 3.3 on another machine and the problem is
 gone.
 
 I traced the change to Makefile.in revision 1.22 (2002-03-08) when
 "ro" merged in changes from ACT.  Now, the GNAT libraries (either
 static or shared) no longer include the file g-trasym.o (package
 GNAT.Traceback.Symbolic), so the feature is unavailable, but "make
 gnatlib-shared" succeeds.
 
 There is still a message "ld: cannot find -laddr2line" when trying to
 link a program that uses GNAT.Traceback.Symbolic, but that is expected.

 The problem is still in gcc-3_2-branch; the symptoms are the same (I
 tried this morning after a fresh cvs update).
 
 I tried to reproduce it on gcc-3_3-branch too, but couldn't bootstrap
 because of an unrelated problem.  I'll file a separate problem report.
 
 Many GNU/Linux distributions now include gcc 3.2 with Ada support; the
 ones I've looked at (Red Hat >= 8, Debian sarge) have patches that
 disable symbolic traces of exceptions (see g-trasym.adb, g-trasym.ads
 under gcc/gcc/ada).  This is the only feature of gnatlib that requires
 libaddr2line.

 Hello,
 
 gcc 3.1 is now a bit outdated. Would it be possible to check whether  
 this problem still exists in more current versions of gcc (ie 3.2.3)?  
 Thanks,
 
 Dara

I tried to remove libaddr2line from the MISCLIB variable and I can now compile the shared library. However, I cannot link hello world against it:
