my problem is i successfully adding my defined unit in delphi2.0 project but in lazarus project i do not know how to enter path of my unit'D:\Lazarus\Pantip' to other project.because the explanation in stack overflow did not indicated that where to put it on path editor or other unitfiles(-Fu) meanwhile the name of project has already in target file name. my question seem to be a silly one but in thailand there is almost no Delphi or Lazarus code writer so i have no choice but to consult outsiders for responding my difficulty.
