WINMAIN and main in C (Extended) About the functions. The C and C standards require any program (for a “hosted” C or C implementation) to have a function called main, which serves as the program's startup function. I have read your article on 'MFC under the hood' and found it informative because that is the code that I am looking through at this time. The reason is that my application is failing in the section. Now let's build it with GUI subsystem, which just means that the program does not require a console window: C: test gnuc x.cpp -mwindows C: test objdump -x a.exe findstr /i '^subsystem' What is the probability that they were born on different days? Excuse me if this is basics, I'm a begginer to split files. I'm new to win32 application building using C. I'm using DEV C and I'm able to get a window, by using the 'windows application' icon in DEV. I want to know how to display our text on to the window??? Win32 api is the MS-Windows operating system functions, all programs that run under MS-Windows. Apr 22, 2014 f1.cpp:(.text+0xc): undefined reference to `foo' and if you compile f2.cpp on its own, you get this even more frightening one: crt0c.c:(.text.startup+0x39): undefined reference to `WinMain@16. In this situation, you need to compile both the the source files on the same command line, for example, using GCC: $ g f1.cpp f2.cpp -o myprog.
But in the end my compiler comes with a lot of errors, all of them is:
[Linker error] undefined reference to `Something'
basically any command in the source code (Any SDL commands that is).
I have read in other threads, that it's because i have forgotten to include the library, but i think i have.
I'm using the dev-c++ compiler.
I went into the: Tools fan, and then chose: compiler options.
Then i chose Directories.
After that i went to the: 'Directories' fan.
In here, there are three deifferend things i can include:
Binaries, Libraries, C includes and C++ includes.
I didn't include anything in binaries, since i couldn't find any SDL binaries.
I included the directory called: 'Lib', as the SDL library.
I included the directory called: 'Include' as both the C includes and the C++ includes, since i didn't know which of them it was supposed to be included as.
SDL, needs to be installed, and as so, it get's a stand alone directory, in C:/Program files/SDL (Or whereever you choose to locate it), the directorires i refer to, that i included, are all directories located in that directory.
So it seems, to me, like i included about everything, that's supposed to be included.
It should be said that i'm learning C++. so i'm a n00b at this. I'm new to both the langauge and the compiler, though i have programmed in another langauge, for pretty some while.
But since i'm new, i would ask you to now assume that i can anything, cause i realy can't. So please help me, step by step, i haven't even made the source code. It's from my stipendium.
O, and please tell me why i have to do what i have to do. I don't just wanna know how to fix it, i also wanna know why i'm fixing it the way i am, since i'm learning the langauge, i would also like to learn from this mistake ^^
i would also like to know how to correct the error, from the title. ([Linker error] undefined reference to `WinMain@16') i have came to the understanding, that, that specific error has another way to be corrected, than the rest.

>[Linker error] undefined reference to `WinMain@16'
You've created a project that's being built as a Win32 application. Those guys use WinMain instead of main as the entry point. If you want a regular C++ program, you have to choose the correct project type (which would be a console project of some sort) or build it yourself manually from the command line.

That'll be very helpfull!
This is the readymade code generated by DEV

Since you are new to win32 you should have read '>this tutorial
Use '>TextOut() for drawing text in a window. '> Here is a YouTube video that shows how to use it.
Mingw Winmain
