Systems using processors that implement the DEC Alpha architecture and

In Tru64 UNIX V5.1, Compaq introduced a new assembler that does not

we need to use the old assembler, invoked via the barely documented

@example

% CC=cc @var{srcdir}/configure [@var{target}] [@var{options}]

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}.
