c++ - Debug dll and doesn't contain the architecture x86_64

Question

I build a 64-bit dll in Clion. Tollchain Visual Studio

The project compiles successfully. For debugging I use Win64 host application compiled in Delphi. I added this application in the configuration editor and when I start debugging I get the message

'Project.exe' doesn't contain the architecture x86_64
Process finished with exit code 0

The application itself without a debugger (or from under the Visual Studio debugger) starts and loads my dll.

---

Additional info

I have compiled an empty Delphi project

program Project1;

{$APPTYPE CONSOLE}

begin
end.

When I run it from under the debugger as a host application, I get the same error.

When running an empty project built in Visual Studio as an host application

int main()
{
}

the debugger starts without errors

Platform: Win64

For comparison PE Headers Delphi and VC programs

Answer 1

My guess is that Clion tests for the Machine Type flag in the COFF File Header. Unfortunately, I don't know of any built-in way in Delphi to set this value.

The best option would therefore be to create a tiny Delphi program that can set this value to the correct value

CONST IMAGE_FILE_MACHINE_AMD64 = $8664;

that you then execute as a post-build event.
