You must also pass the source root with -I:
-IC:\MyProjects\D\Pegged
(and maybe you miss another source since there are 5:
'..\repos\Pegged\pegged\grammar.d'
'..\repos\Pegged\pegged\parser.d'
'..\repos\Pegged\pegged\peg.d'
'..\repos\Pegged\pegged\dynamic\grammar.d'
'..\repos\Pegged\pegged\dynamic\peg.d'
)
By the way with Coedit you wouldn't have this kind of problems
(Pegged is part of metaD). You can even run some test on Pegged
without saving the file / without a project (this is called a
runnable module). This is just what I've done.
At least compile pegged as a static lib, then it's simpler, you
just have to pass the -I<root> pegged.lib and your custom sources
files.
