Linking error: undefined reference to `WinMain'

[gp]

Hi all,

I have built the framework and ran some testing examples successfully.

But now, I'm trying to integrate the framework to a real project and I'm getting the next linking error:

make -f makefile.test

Linking uartSample_main_tests

/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../lib/libcygwin.a(libcmain.o): In

What could be the problem?

I appreciate your help!

Thanks a lot.

It is now building as a Windows GUI application and you are not providing a WinMain(), the Windows version of main.

Hi Wayne,

Thanks for your answer.

I need to build from a cmd window (console) not like Windows GUI.

What should I change to do this?

Thanks a lot!

I am sure it has something to do with the compiler/linker flags you are using. This will probably depend on the compiler you are using.

Unfortunately, it has been some time since I have really worked on Windows so I don’t know the specific answer. I am sure that Google will provide the answer *if* you can come up with the correct search terms.

Hi Giovanni,

 

It's rather unusual for Cygwin Gcc to want to build a Windows GUI application - what kind of Makefile are you using? What does your main() function look like?

Hi Robert,

It is solved, the runner code was missing.

Thanks a lot!.
