lazmouseandkeyinput Linux mint 19.2 (SOLVED) lazarus / 32-Linux ---------------------------------------------------------------------- TheLastCayen · 2019-11-06 17:54 Hi, I am using:  - Linux Mint Xfce 64 bit  - Lazarus 2.0.6 64 bit  - FPC 3.0.4 I create a new project. I compile without any error. The project show an empty form as expected.  I build and add /usr/share/lazarus/2.0.6/c omponents/mouseandkeyinput/lazmouseandkeyinput.lpk.   I try to compile again and this is the error message I receive: project1.lpr(21,1) Error: Error while linking This is the code generated by lazarus after I added lazmouseandkeyboardinput: project1.lpr: Code: Pascal  [Select][+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i  program Project1; {$mode objfpc}{$H+} uses  {$IFDEF UNIX}{$IFDEF UseCThreads}  cthreads,  {$ENDIF}{$ENDIF}  Interfaces, // this includes the LCL widgetset  Forms, unit1, lazmouseandkeyinput  { you can add units after this }; {$R *.res} begin  RequireDerivedFormResource:=True;  Application.Scaled:=True;  Application.Initialize;  Application.CreateForm(TForm1, Form1);  Application.Run;end.                       I originally tried with the version of lazarus shipped with my operating system, Lazarus 1.8.2 and FPC 3.0.4. I had the same issue and this is why I installed the last version.  Anyone know how to fix this issue? ---------------------------------------------------------------------- bytebites · 2019-11-06 18:10 Install libxtst and libxtst-dev ---------------------------------------------------------------------- TheLastCayen · 2019-11-06 19:48 I can't find libxtst but installing libxtst-dev seems to fix the issue. Thank you:) for future reference: sudo apt-get install libxtst-dev
