Re: Undefined reference

Hello,

I'm again getting undefined references in the libstdc++ test suite
(this time 21_strings/basic_string/cons/wchar_t/2.cc).  The symbol is

std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::_S_construct(unsigned long, wchar_t, std::allocator<wchar_t> const&)

Is this again a problem with the version script?

Hi,
we are all getting it, on the various wchar_t enabled platforms.
Both 3.2 and 3.3 have no problem with this new wchar_t test, constituted basically by a single line:

std::wstring s(10, 0);

Notice that there are no differences in the basic_string code itself present in the various branches (3.2, 3.3 and 3.4) and the problem appear at link time and only for dynamic linking, therefore probably your guess is correct. Unfortunately I haven't made much progress yet in trying to understand what is going wrong.

Do you have any hints?

Paolo.
