Systems using processors that implement the DEC Alpha architecture and
are running the DEC Unix (OSF/1) operating system, for example the DEC
Alpha AXP systems.CC.)
are running the DEC/Compaq Unix (DEC OSF/1, Digital UNIX, or Compaq
Tru64 UNIX) operating system, for example the DEC Alpha AXP systems.
In Tru64 UNIX V5.1, Compaq introduced a new assembler that does not
currently (2001-06-13) work with @command{mips-tfile}. As a workaround,
we need to use the old assembler, invoked via the barely documented
@option{-oldas} option. To bootstrap GCC, you either need to use the
Compaq C Compiler:
@example
% CC=cc @var{srcdir}/configure [@var{target}] [@var{options}]
@end example
or you can use a copy of GCC 2.95.3 or higher built on Tru64 UNIX V4.0:
@example
% CC=gcc -Wa,-oldas @var{srcdir}/configure [@var{target}] [@var{options}]
@end example
GNU CC writes a @samp{.verstamp} directive to the assembler output file
unless it is built as a cross-compiler. It gets the version to use from

If you install a shared libstdc++ and, when you link a non-trivial C++
program (for example, @file{gcc/testsuite/g++.other/delete3.C}),
the linker reports a couple of errors about multiply-defined symbols
(for example, @code{nothrow}, @code{__throw} and
@code{terminate(void)}), you've probably got a linker bug, for
which there's no known fix. The officially recommended work-around is
to remove the shared libstdc++.
An alternative solution is to arrange that all symbols from
@code{libgcc} get copied to the shared @code{libstdc++};
see detailed solution below. (Surprising as it may seem, this does
indeed fix the problem!) @emph{Beware} that this may bring you
binary-compatibility problems in the future, if you don't use the same
work-around next time you build @code{libstdc++}: if programs
start to depend on @code{libstdc++} to provide symbols that used
to be only in @code{libgcc}, you must arrange that
@code{libstdc++} keeps providing them, otherwise the programs
will have to be relinked.
The magic spell is to add @option{-Wl,-all,-lgcc,-none} to the
definition of macro @code{SHDEPS} in
@file{libstdc++/config/dec-osf.ml} @emph{before}
@file{alpha*-dec-osf*/libstdc++/Makefile} is created (a
@uref{dec-osf-shlibstdc++.patch,,patch}
that does just that is available). If the Makefile already exists, run
@file{./config.status} within directory
@file{alpha*-dec-osf*/libstdc++} (and
@file{alpha*-dec-osf*/ieee/libstdc++}, if it also exists).
Remove any existing @file{libstdc++.so*} from such directories,
and run @samp{make all-target-libstdc++} in the top-level
directory, then @samp{make install-target-libstdc++}.
If you have already removed the build tree, you may just remove
@file{libstdc++.so.2.10.0} from the install tree and re-create
it with the command
@samp{gcc -shared -o libstdc++.so.2.10.0 -Wl,-all,-lstdc++,-lgcc,-none -lm}.
If the @file{ieee}
sub-directory exists, repeat this command in it, with the additional
flag @option{-mieee}.
