lazarus 编译的程序在linux运行时出现：Failed to create OS basic event with name ""

lazarus 编译的程序在linux运行时出现如果出现这个错误提示：Failed to create OS basic event with name ""，建议检查一下project是否开启开线程，如没就添加红色代码就可以。

program project1;

{$mode objfpc}{$H+}

uses
  {$IFDEF UNIX}//加上这行
  cthreads,    //加上这行
  {$ENDIF}     //加上这行
  Interfaces, // this includes the LCL widgetset
  Forms
  { add your units here }, Unit1, rtcSDK_FPC;

{$R *.res}

begin
  Application.Scaled:=True;
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.
