    iostream problem. Help! :P

    Hi, I just installed DJGPP with Rhide as IDE.

    When I tried to do a test program, I had an error. The program I did is as follows:

    #include <iostream>

    int main()
    using std::cout; // or using namespace std;
    cout << "Hello World";
    return 0;

    The code above compiled with 0 errors but when it was creating the .exe file, it throws this error:

    Error: c:/djgpp/lib/gcc-lib/djgpp/3.1/libstdcxx.a(c++locale.o): In function 'void std::__convert_to_v<float>(char const*, float&, std::_Ios_Iostate&, int* const&, int)':
    c++locale.o(135) Error: undefined reference to '_finite'
    Error: collect 2: ld returned 1 exit status

    Anyone knows what it means? Thanks

    Try placing 'using std::cout;' or 'using namespace std;' outside of main() - under the #include <iostream>.

    I'm not familiar with DJGPP but can guess that it's trying to compile 'using std::cout;' as part of the program with some rather bizarre results.

    Er, I have no idea what that error is trying to say but as far as I can tell that code should work

    The code is fine as I compiled it.

    So the next two thing that it could be are:

    1. Your compiler is incorectly set up.
    2. DJGPP does not support using namespace std.
