    Unhappy LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16

    Compiling my first tutoriol/program, goes fine. Building gives this error:

    Linking...
    LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16
    Debug/helwld.exe : fatal error LNK1120: 1 unresolved externals
    Error executing link.exe.
    Creating browse info file...

    helwld.exe - 2 error(s), 0 warning(s)

    I am new to C++ but have followed the directions on the tutorial, whcih says: to set the options>idirectories>include "\include directory of the Irrlicht Engine ", and to clcik libraries and put in the library path for VS studio in for the same machine above.s After researching I also Ihave put the Irrlicht.lib in the project settings link list as well.

    This is an xp running VS 6.0 C++

    I dont know what else to add...

    [B]OH ohB]the tutorial said if you get the first error then you have done the options/directories include wrong, but I have checked it several times....

    I have searched the msdn for info on the #pragmatic statement too, and all looks acurater there...

    Thanks for any help

    Is that the C# language? If so, you'd be better posting it on that board. Doesnt look like C++ or C to me

    For a starter, what's with the "L" in the line below:

    Code:
    guienv->addStaticText(L"Hello World! This is the Irrlicht Software engine!",	 
    		rect<int>(10,10,200,22), true);
    And maybe for the linking error, maybe you've created a new Windows project but you used "int main()" not the WinMain(...).

    Isn't that how you say that a string literal is made up of 2-byte characters instead of 1-byte characters? That looks hauntingly familiar from internationalization changes I made a while back, but it's been...a while.

    Aye, dead on. If this is a Windows app, you need a WinMain. If it's supposed to be a console app, your project settings are wrong.
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Note that there is a 'L' in front of the string: the Irrlicht Engine uses wide character strings when displaying text.

    What???

    This is the url for the tutorial:
    http://irrlicht.sourceforge.net/tut001.html

    I added the WinMain and still get the same two errors.

    Thanks much for helping.

    Well the best way is: Start a new project. Choose console (not windows) application. Copy-paste the tutorial to the main function.

    Are you still there? what is the difference between console and windows?

    Thanks, I just didnt understand your question.... I have never coded in C++ before this was my first program, and I havent done any coding in anything but html and a little java in several years. But its time to retrain so I can build some games......smaile

    A GUI looks like your browser.
    A console may look like this.

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    oh, yes, I understand. I didnt know C++ had a console to write code in. Will do, thanks.

    Ok, did that and got the same error. So I guess thats not it either.

    Too bad, Ive got 4 more coded, but since they use the same setup they wont work either.

    IVE GOT IT! As I thought it was something simple, no .dll in exe folder. Oh well, thats what starting at the beggining means. At least there is an answer here for someone else.
