Subject: gcc 3.2 string<wchar_t> link problem
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

Hello all,

Having happily upgraded my Cygwin to include gcc 3.2, I've
encountered a show-stopper: The linker can't resolve symbols
involving wide C++ strings.  Here is an example:

#include <string>
#include <iostream>
using namespace std;

int main(int argc,char *argv[])
{
        std::string<wchar_t> test;
}

-----------------

$ g++ test.cpp
/cygdrive/c/DOCUME~1/nigels/LOCALS~1/Temp/ccHP4AMl.o(.text+0x25):test.cpp: 
undefined reference to `std::basic_string<wch
ar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> 
 >::basic_string[in-charge]()'
/cygdrive/c/DOCUME~1/nigels/LOCALS~1/Temp/ccHP4AMl.o(.text+0x30):test.cpp: 
undefined reference to `std::basic_string<wch
ar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> 
 >::~basic_string [in-charge]()'
collect2: ld returned 1 exit status

---------------------------

Any hints, suggestions, or duh-read-the FAQ responses, appreciated.

Note that the following compiles & links:

int main(int argc,char *argv[])
{
        std::string<double> test;
}

----------------
