You must configure your project settings. A quick web research shows that others had similar problems: c - undefined reference to WinMain@16 (codeblocks) - Stack Overflow. Dev C Undefined Reference To But none of them is surely not possible. But the new problem am having now is that the class implementation and the program am trying to run must be in the same file before it can work. I get 'Undefined reference to 'WinMain@16' Under Visual C, you need to link with SDL2main.lib. Under the gcc build environments including Dev-C, you need to link with the output of 'sdl-config -libs', which is usually: -lmingw32 -lSDL2main -lSDL2. I get undefined references to various SDL functions.
I just had the exact same problem working with the exact same tutorials. How to solve this? I found that restarting CodeBlocks gets rid of this So there is no place in memory where b actually resides (the reference is undefined). To deal with this, you have to manually declare it in a cpp file, with the syntax int A::b; . This way you are reserving some space for that variable
When I compile my secrypt.cpp program, my compiler shows the error 'undefined reference to WinMain@16'.my code is as follows
secrypt.h :
secrypt.cpp :
trial.cpp
Here is the image of my error:errorimage
When I compile my trial.cpp program, it compiles and opens the console, but didn't calls the function. Here is the image of the console screen of trial.cpp program .o/p screenCan anyone help me solving this?

When there's no project, Code::Blocks only compiles and links the current file. That file, from your picture, is secrypt.cpp, which does not have a main function. In order to compile and link both source files, you'll need to do it manually or add them to the same project.
Contrary to what others are saying, using a Windows subsystem with main will still work, but there will be no console window.
Your other attempt, compiling and linking just trial.cpp, never links secrypt.cpp. This would normally result in an undefined reference to jRegister(), but you've declared the function inside main instead of calling it. Change main to:

Well I know this answer is not an experienced programmer's approach and of an Old It consultant , but it worked for me .
the answer is 'TRY TURNING IT ON AND OFF' .restart codeblocks and it works well reminds me of the 2006 comedy show It Crowd .
undefined reference to 'WinMain@16' collect2.exe: error: ld returned 1 exit status. (When I compiled main.c) undefined reference to 'ListInit'. When all the source files has been compiled everything is linked together to create the executable file. If cordinates.cpp is not part of the project it would notice that some of the definitions are missing and give you a linker error 'undefined reference'. There is no magic relationship between source files and header files.
I was interested in setting up graphics for Code Blocks when I ran into a this error: (took me 2 hrs to solve it)
I guess you need to have a bit of luck with this. In my case i just changed the order of contents in Settings menu->Compiler and Debugger->Global compiler settings->Linker settings->Other Linker Options:The working sequence is:-lmingw32-lSDL-lSDLmain

You should create a new project in Code::Blocks, and make sure it's 'Console Application'.
Add your .cpp files into the project so they are all compiled and linked together.
undefined reference to This error is often generated because you have typed the name of a function or variable incorrectly. For example, the following code: Get latest updates about Open Source Projects, Conferences and News. Sign Up No, Thank you
You need to open the project file of your program and it should appear on Management panel.
Right click on the project file, then select add file. You should add the 3 source code (secrypt.h, secrypt.cpp, and the trial.cpp)
Compile and enjoy. Hope, I could help you.

Open the project you want to add it.
Right click on the name.Then select, add in the active project.Then the cpp file will get its link to cbp.

I had the same error problem using Code Blocks rev 13.12.I may be wrong here since I am less than a beginner :)
My problem was that I accidentally capitalized 'M' in Main() instead of ALL lowercase = main() - once corrected, it worked!!!
I noticed that you have 'int main()' instead of 'main()'. Is this the problem, or is it supposed to be that way?
Hope I could help...
error. You could fix this problem in both the Project -> Properties and in File -> Properties dialogs. Undefined reference to WinMain@16 . Undefined reference to WinMain@16. Soldier8D. I have seen posts about this problem before, and tried everything within them.
Re: [Dev-C++] Error: undefined reference to `WinMain@16' two .h, = three .cpp files) in Dev-C++ 4.0 I get the following error from Compiler = and linker But be aware that then your main() method will be called by a 'dummy' WinMain() function implemented in 'qtmain.lib', it will NOT be called by the C-Runtime directly.
Hello Guys,I've just started programming C with Dev-C++ and am just trying to program a kind of role play (only fighting, nothing very good)
I had to create some Librarys and stuff and because of the possibility to have the same Library in the code, I used
and
and after the Main function, I ended with
this is the whole code:
So, after compiling, it says:
[Linker Error] undefined reference to 'WinMain@16'
I tried some things and came to the solution, that #endif can't be after the main function,
but it also cannot be in the main function,
so I guess, that I have to put #endif somewhere else, but where?

before the main function doesn't make sense, because then, I could leave that out as well.
Can anyone help me with this?
