Trivial C runtime. Linker error

[Loizos]

I am giving a shot on BigBoote's tutorial "Writing your own packer".

 

Right at the beginning of the project I ran into linking problems.

 

As a result of not using the default libraries(on purpose) , the linker complains about the unresolved external symbol __ DllMainCRTStartup@12

 

In order to fix the linking error the author suggested on replacing the DllMain function with DllMainCRTStartup.He claims that this will fix the linker's error and at the same time be the EP.I've tried replacing the Boiler-Plate DllMain function with the DllMainCRTStartup  but the problem is still there.I have done my research and I can't seem to find anyone that had similar problems.

 

Any ideas?

 

BOOL WINAPI _DllMainCRTStartup ( HANDLE, DWORD, LPVOID )
{
//Program will go here
return TRUE;
}

What dev environment do you use?

If you use Visual Studio, try setting the entry point to DllMain in your linker settings of the project

Problem solved!The linker doesn't complain anymore.Setting it as an EP makes sense , I don't know why I haven't thought of it. Thank you.
