Hi everybody,
I am studying the cairod library and running some examples. I am using DDT and the example is a dub project. Moreover one of the source file of the program is outside 'src' folder where the main file is present.
My problem. Debugging the program it happens, going step by step, to pass to function defined into a package.d file, but DDT returns an info: "can't find a source  file at..." and I cannot follow anymore the rows under debug. I cannot even place a breakpoint. Even if at the location indicated by DDT the file exist and the source should be the correct one.
If I move that file within the 'src' directory I can still compile and I can follow the execution row by row also inside the moved file.
I am looking for a way to include among the source files, in a DUB project in DDT, a directory that is not the 'src' one foreseen for the project directory.
I've tried with gdb and it works. With gdb it was enough to include the directory includes the package.d file and I had no issue. I do not know how to let it works using DDT. I've tried several options but no one was actual. I did several searches on Internet with no good results.
Maybe the behavior is correct, I do not know. Anyone can explain to me the matter?
Thanks,
Luigi

Sorry for late reply, but I don't typically check the D.debugger newsgroups (if you have a question about DDT, you can open a Github issue for that, that will guarantee faster response).

As for your issue, did you try the settings in the debug configuration? In the "Source" tab ( https://raw.githubusercontent.com/DDT-IDE/DDT/latest/documentation/screenshots/UserGuide_DebuggerLaunchConfiguration.png ) you can configure additional source mappings for the Eclipse debugger to find the .d source files.
