I've tracked down similar link errors on Google:

I'm getting some unresolved symbols when trying to compile C++ programs using specific char_traits.
In function `std::basic_string<TestType, std::char_traits<TestType>, std::allocator<TestType> >::assign(TestType const*)': : undefined reference to `std::char_traits<TestType>::length(TestType const*)'
As far as I have looked, the char_traits are correctly _declared_ for every template, but the member functions of the struct are defined only when using 'char' or 'wchar_t' as template type.
Again, this bug has been fixed in the new version of the libstdc++ (version 6 provided with g++-3.4), and making an adapted copy-paste of the 'char_traits.h' file should be an acceptable solution (works fine for me).
Except for blackbox the undefined reference is a basic_string::assign() function. Seems like a GCC problem to me. I just compiled it with CXX=g++-3.4, and it works.
But I thought it would be worth mentioning, incase some other Debian users run into this problem.
... or fedora core 2 users....
... or SuSE 8.2/9.1 users (gcc 3.3 and gcc 3.3.3)...
Could anyone explain above mentioned workaround? "making an adapted copy-paste of the 'char_traits.h' file" seems rather vague to me.
