So far I compile code using terminal via ldc2. I compiled the app 
using '-g' flag and then compiler created a .pdb file. When I 
started debug I've got the same error. I decided to change 
debuggers for one more test (mago, gdb and cpp). I got the same 
errors. Then I return debugger to gdb and now I get the error 
"Failed to load MI Debugger". Not inexecutable format. Just app's 
launch works. These errors I got in the VS code. In IntelliJ IDEA 
now I get the error 'No symbol table is loaded.  Use the "file" 
command.'
What's the right path for dub.json?
