where is this file emitted from?

[Dirk Pranke, 2016/07/20 22:37:41]

The :courgette(//build/toolchain/win:x64) dependency on line 139 produces that
file.

You could perhaps make this clearer by writing:

  _courgette64 = ":courgette(//build/toolchain/win:x64)"

  sources = get_target_outputs(_courgette64)
  deps = [ _courgette64 ]

+        ]
+        outputs = [
+          "$root_out_dir/courgette64.exe",
+        ]
+        deps = [
+          ":courgette(//build/toolchain/win:x64)",
+        ]
+      }
     }
   }
