    Explanation of a Compilation Error Needed

    Hello,

    I'm currently working on implementing a Vector in C. When I compile my Vector.c file, I get the following message:

    [Linker Error] undefined reference to 'WinMain@16'

    What does this mean exactly? My file is just a bunch of functions based off of a Vector.h header file. There is no main in it. Does that have something to do with it? I'm sure this is answered somewhere on this site, but I couldn't find anything.

    if you're trying to compile your file as a header you have to use the .h extension. If you compile as a .c extension, it's going to look for a main() function. I'm not quite sure what you're asking about, I hope I helped.

    It means you're compiling your console app (which begins with main) as a windows app (which begins at winmain)

    Go change your project to compile as a console app

    Yes, this has been discussed many times before
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
