The showwindow doesn't work under Linux yet. The component was originally
written for Win32 and not all of the windows features have been ported.

Look at the testproc.pp example; the options you should use for compiling
are in that example:


Var S : TProcess;
    Buf : Array[1..BUFSIZE] of char;
    I,Count : longint;
    Line : String
begin
  S:=TProcess.Create('/path/to/ppc386 myfile.pp',[poExecuteOnCreate,poUsePipes,poNoConsole]);
  Repeat
    Count:=s.output.read(buf,BufSize);
    // Display buf in a memo, or parse it...
  until Count=0;  
  writeln;
  S.Free;  
end.
