           Summary: C++ support on alpha is no more
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: libstdc++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: mmazur at kernel dot pl
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: alpha-pld-linux-gnu

While trying to compile anything (is it python or ncurses) ./configure shows me
that _Unwind_Rewind_or_Rethrow@3.3 doesn't exist (checking if the c++ compiler
is able to produce executables... no :). Unable to compile ncurses? That renders
the system completely useless. I haven't tried anything else but I assume there
would be the same problem.

Had to switch to using _Unwind_RaiseException
(libstdc++-v3/libsupc++/eh_throw.cc:100). It builds. No idea if it will work
though. Will it?

There are lots of people for which g++ 3.3 on Alpha works just fine. I suspect
it's rather an installation problem. So we need some more information:

- the exact command you used to build and install gcc,
- the exact command you called it with,
- the program you called it on.

This is ncurses 5.3 building (I got the same problem with some python code).

As for the exact command. Hmmm. You can find the spec it was built from at
http://cvs.pld-linux.org/cgi-bin/cvsweb/SPECS/gcc.spec (note: currently the
patch that fixes above errors gets applied when building on alpha). What it's
worth - the spec is very old well tested and works on every other arch (+ it
worked for the previous version of gcc on alpha without those damn c++ problems)
so as far as I can tell the problem doesn't come from here. Can't think of any
other usefull information.

Please send the output of g++ -v.

Can you test with an unmodified version of gcc?

During the libstdc++-v3 configure step, look for this line:

checking for exception model to use... [result]

I would expect the results you are seeing if the library was configured to use
one model, but the compiler was configure to use a different one.

Alternatively, look at the configure arguments for the compiler rpms.  If any
of them pass --enable-sjlj-exceptions (or --disable), then that will have the
same effect.  The compiler and library must be configured and built with the
same exception model.

Exception models do not differ.
Will be checking gcc 3.3.1 in a moment. From what I've heard the code where I
apply my patch has changed. Worth a try.

Nope. 3.3.1 still broken. Any other ideas (eg. how do I debug stuff like this)?

I would look at see which libgcc_s.so ld is picking up because it looks like it is picking the wrong 
one up.

Bingo. There was some old libgcc_s.so in /usr/lib while mine is in /lib.
/usr/lib obviously took precedence. Sorry for the trouble.
