    How to compile .cpp with gcc (NOT g++)

    I tried this one, but did not work
    Code:
    gcc -x c++ prog.cpp
    // gives "std::basic_string" undefined reference
    oh, yeah, g++ keeps give me warning about "no newline at EOF" even though I have thousands of blank line at the end of code. What sup with that?

    But "gcc -x c++" is g++
    Isn't it?
    Where's the code?

    In my practice, those two do not give equal result

    >>
    Code:
    #include <iostream>
    int main() {
        std::cout << "Hello,  world\n";
        return 0;
    }

    gcc -x c++ hello.c -lstdc++

    Which text editor are you using to create your source code file?
    If you understand what you're doing, you're not learning anything.

    It's a convention that the last character in a plain text file (such as source code) is a newline. Otherwise - well, output the file with cat and see for yourself where your prompt ends up.
    gcc emits a warning when this is not the case.

    Why can't you use g++?

    Something's wrong with my kdevelop. I did cat, all the newlines are there at the end of file yet the compiler warning persists. I open and simply re-save with vi and it compiles with no warning.
    And I was just curious of the equivalence of g++

    g++ is usually merely a symlink to gcc, and gcc knows to assume C++ code and the C++ standard library if it's called via that link.

    can I just say that this is one of the most gorgeous/priceless statements ever??

    take the hint my friend, and use vim for your coding...

    VIM + gcc + beer... does life get any better?

    Edit the option in kdevelop to use "\r\n" for newlines rather than "\n" or whatever it uses. Tell me if that works.

    The original question was answered a month ago, the rest was off-topic wibble which wound itself to a close.

    See...
