module systemsolver;
import std.stdio;
class SystemSolver

  this()

    writefln("Constr!");
  }
}

===main.d==
import std.stdio;
import systemsolver;

void main(char[][] args)
{
  writefln("Hello World, Reloaded");
}

these 2 files are in the same dir. When i try to compile main.d i get error:

You need to use:

$ dmd main systemsolver

DMD will only compile the files you *tell* it to compile.

It's a silly limitation of DMD I hope to see solved soon. In the meantime this
limitation can be written in the FAQ to warn newbies, and there are a couple of
tools (I use one called "bud") that can solve that problem.
