undefined versioned symbol from GLIBCPP_3.2

[Nicolas F Rouquette]

Can someone provide some advice about resolving this type of error?

undefined versioned symbol name std::basic_string<char, 
std::char_traits<char>, std::allocator<char> >::find_first_not_of(char 
const*, unsigned, unsigned) const@@GLIBCPP_3.2

In principle, I understand that the linker is telling me that this 
versioned symbol isn't found in any of the libraries given.
However,  I'm puzzled that this is a symbol from the standard library, 
not one of my own.

I built from sources gcc 3.2 on RedHat 7.3.
I'm trying to link a shared library made of C++ object files.

Any suggestions?
