Thread: How am I getting this error

How am I getting this error
error LNK2001: unresolved external symbol _WinMain@16

I deleted a function prototype in one of my headers which I no longer needed, and then I started getting that error. Hmmm

What compiler are you using? Usually when people are writing Win32 app's for the first time they will get that error but with external symbol _main. This is because they are trying to make the Win32 program using a console project in M$VC. So I would assume you don't have WinMain correctly declared or one of your project options got tinkered with?

read the forger site, but to sum it up its like this:

you are trying to call a function that is contained in another module other than what modules and libraries you are currently linked to.

the most common error, said forger's site, is trying to compile a win32 app with a "console project" like sean said.

or trying to compile a console program and didn't properly write or compile the main() function.

if you're using VC++ re-create your project with a win32 project, not console.

if you're using BC++ it says to use -tW however i don't know what thats all about because i use VC++.

it also said it can happen if you try and compile a BC++ program from the command line and dont specify the correct parameters to tell it that its a win32 app.

btw, did it run fine before you changed the code?

yes it ran fine before i changed my code

I deleted eveverything except the source workspace and data files and rebuilt the project and that solved the problem
