linking/compiling problem

[dschulenburg]

I am writting a cod in C in visual C++. Does anyone know what this linking error means and how I can avoid it ?

MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function _WinMainCRTStartup
.\Debug/BiofilmInPores.exe : fatal error LNK1120: 1 unresolved externals

2 stages are there to run a program "compiling and linking"
after you compile with "CL.exe"which produce .obj and other intermediate files....then Link.exe will uses those intermediate files to create .exe files...
Your problem is while Linking...

Actual answer to your question is "you have to choose new->win32 console application"

You must have selected "win32 application"...

Actually, you want top create a Win32 project and when the wizard appears you do not click Finish.

Instead, click application settings and then select Console Application and Empty project. Then click Finish.

If you create Win32 Console applcation, you get a _tmain() and an stdafx.cpp file set up for a Windows console application. I do not believe you are doing Windows programming.

A Console Application and a Windows Console Application are two different thisngs.

Great thanks ! But now the compiler does not accept macros. Do you know what I have to change ?

How do you mean?

The compiler has nothing to do with macros.

The build process calls the preprocessor which processes all of # directives. The processed file (called a translation unit) is what is passed to the compiler so the compiler never sees your macros.

You haven't inadvertantly set the Create/Using Precompiled Headers property to using precompiled headers have you??

If so, go to your project Properties, select C/C++ /Precompiled Headers and set Create/Using Precompiled Headers to not using precompiled headers.
