Note that this is different from the default "obj" for Object_Dir.

How did you edit this gpr file? if you did not use the GNAT Studio
Preferences editor, GNAT Studio does not know about this change from the
default.

I'm assuming you meaning the .exe is "D:\Ada Programming\Object
Files\my_sdc.exe", since that's what the gpr file says.

This indicates GNAT Studio is not using the gpr file you want it to.

You can discover what GNAT Studio thinks the project file is by hovering
the mouse over the root folder in the Project window; for the Hello
World project I created, this shows
"/Projects/hello_world/hello_world.gpr" (I'm on Debian, hence the Unix
directory separators).

You need to specify your gpr file as the project file to open.

If you've edited the project file after you opened the project, you need
to tell GNAT Studio to read it again. I don't know how to do that short
of close the project and open it again.
