Hi Brad, Thanks for the hint.

Hmm. So the "inline namespaces" all appear to happen in c++config.h,
which I found on the alpha in
/usr/include/c++/4.4/alpha-linux-gnu/bits/c++config.h
Given the pathname, I assume there are arch-specific bits in there.
Indeed, the file differs between alpha and x86_64. However, I found
that I had to put it into GCC/4.4/bits/c++config.h -- and NOT
GCC/4.4/alpha-linux-gnu/bits/c++config.h to get gccxml to find it.
It's not clear to me how to do this tweaking in an architecture-specific
manner.
Anway, I did it by hand on alpha and the compile now fails elsewhere:
In file included from /usr/include/c++/4.4/bits/locale_facets.h:2599,
from /usr/include/c++/4.4/bits/basic_ios.h:39,
from /usr/include/c++/4.4/ios:45,
from /usr/include/c++/4.4/istream:40,
from /usr/include/c++/4.4/sstream:39,
from /usr/include/c++/4.4/complex:47,
from complex.cc:1:
/usr/include/c++/4.4/bits/locale_facets.tcc:1279: error: explicit instantiation
of non-template 'const int std::num_put'
/usr/include/c++/4.4/bits/locale_facets.tcc:1279: error: expected `;' before
'<' token
.... plus plenty more similar ...
The line in question contains this:
extern template
const num_put<char>&
use_facet<num_put<char> >(const locale&);
I'm stumped again. The output from gccxml -E complex.cc contains this
namespace __gnu_cxx_ldbl128 {
template<typename _CharT, typename _InIter = istreambuf_iterator<_CharT> >
class num_get;
template<typename _CharT, typename _OutIter = ostreambuf_iterator<_CharT> >
class num_put;
}
I'm not sure why locale_facets is looking for std::num_put but
it is really in namespace __gnu_cxx_ldbl128. Any ideas?
Thanks,
-Steve
