    I have problems to build the following
    small C++ programm with g++ 3.2.3 at a
    HP-UX B.11.11 U 9000/800.

    #include <sstream>
    #include <string>
    #include <iostream>
     
    using namespace std;
     
    int main()
    {
       std::stringstream ss;
       std::string str;
       ss << 4; ss >> str;
       std::cout << "str: " << str << std::endl;
       return 0;
    }

    I get a linker error from HPs linker:

    /usr/ccs/bin/ld: Unsatisfied symbols:
       std::basic_stringstream<char, std::char_traits<char>, std::allocator<char> >::~basic_stringstream
    [in-charge]()(first referenced in /var/tmp//ccvy3bfa.o) (code)
       std::basic_stringstream<char, std::char_traits<char>, std::allocator<char>
    ::basic_stringstream[in-charge](std::_Ios_Openmode)(first referenced in /var/tmp//ccvy3bfa.o) (code)
    collect2: ld returned 1 exit status
     

    To get more information I did a:

    1) g++ -c main.cpp
    2) g++ -W,l -v main.o

    Here comes the output:

    gcc was built with "--disable-shared" so the linker does not try link against
    the shared libraries.

    How can I check the gcc installation/enivronment ?
    In the specified directory:
    /usr/local/lib/gcc-lib/hppa2.0n-hp-hpux11.00/3.2.3/../../..
    there exist a libstdc++.

    I did a
    nm main.o | grep stringstream
    and got
    U _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13_Ios_Openmode
    U _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev

    Now I did a:

    my_host(my_user):/usr/local/lib> nm libstdc++.a | grep _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev
    00000000 T _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev

    my_host(my_user):/usr/local/lib> nm libstdc++.a | grep _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13>
    00000000 T _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13_Ios_Openmode

    The symbols are found. What do I missing ?
    How can I further analyze the problem ?
