    Hi,

    I would guess that your application cannot find the dlls at run time. You need to add the path to these to the PATH environment variable. Do that in the Run part of the Project panel.

    I did so
    qt.png

    still the same problem - [99] TLS initialization failed

    @jenya7 You need to add the path to the FOLDER containing the libs without the file name!

      OK. Did so. Removed the name. Still the same problem.

        @jenya7 Does that folder also contain the dll file?

          I ran a search in Qt folder on any ssl related files and found only
          ssleay32.dll in C:\Qt\Tools\mingw730_64\opt\bin and C:\Qt\Tools\QtCreator\bin
          Should I include the paths too?

            I have a problem.
            This way it works - if I initialize explicitly with a string

            telebot::telebot(QObject *parent) : QObject(parent)
            {
                   TelegramBot bot("my_api_key");
                   QObject::connect(&bot, &TelegramBot::newMessage, this, &telebot::NewMessage);
            }
            

            But if I do it with variable

            telebot::telebot(QObject *parent) : QObject(parent)
            {
               if (!sys_params.bot_api_key.isNull() && !sys_params.bot_api_key.isEmpty())
               {
                   TelegramBot bot(sys_params.bot_api_key);
                   QObject::connect(&bot, &TelegramBot::newMessage, this, &telebot::NewMessage);
               }
            }
            

            I get the error
            The inferior stopped because it received a signal from the operating system.
            Signal name : SIGSEGV
            Signal meaning : Segmentation fault

            I see the constructor works before sys_params initialization although I set first line after window activation

            int main(int argc, char *argv[])
            {
                QFuture<uint32_t> discovered;
            
                QApplication a(argc, argv);
            
                MainWindow w;
                w.show();
            
                //here is sys_params initialization 
                SetupRun();
               
                //some other code
            
                  return a.exec();
            }
            
            

            What should I do?

              You are supposed to run your code in a debugger. It will stop on the seg fault, go to the stack trace window to see information about where this is occurring from your code/the code you call.

              Since we have no idea what your sys_params.bot_api_key is or what is in it, and since you say introducing it causes a seg fault, that would be my first suspect.....

              telebot::telebot(QObject *parent) : QObject(parent)
              {
                     TelegramBot bot("my_api_key");
                     QObject::connect(&bot, &TelegramBot::newMessage, this, &telebot::NewMessage);
              }
              

              Your TelegramBot bot is a local variable, it will go out of scope and be destroyed at the end of this constructor. Same applies in your second code attempt. What do you think you are achieving with this code, because it is not right.

                Yes I stop with a breakpoint at
                if (!sys_params.bot_api_key.isNull() && !sys_params.bot_api_key.isEmpty())
                the next step - refering to sys_params.bot_api_key generates the error.

                It's a field of a structure

                typedef struct
                {
                   //some fields
                    QString bot_api_key;

                SYS_PARAMS sys_params;
                

                How can I do it global? It's not like I can instantiate it

                TelegramBot bot;  
                 telebot::telebot(QObject *parent) : QObject(parent)

                    As @jsulm has just written for the seg fault.

                    TelegramBot bot;  
                         bot = new TelegramBot ("my_api_key");  //is not allowed
                    

                    Why do you think this is "not allowed"? What does the compiler error message tell you, I would guess it's pretty clear?

                          As @jsulm has just written for the seg fault.

                          TelegramBot bot;  
                               bot = new TelegramBot ("my_api_key");  //is not allowed
                          

                          Why do you think this is "not allowed"? What does the compiler error message tell you, I would guess it's pretty clear?

                              In addition to @jsulm's excellent points. We don't know the scope of your sys_params (probably "global", yuck, don't do that), and:

                              {

                              We don't know whether you have written anything to the "some fields", or written directly into sys_params.

                                    If I comment out the constructor stuff - I see all fields of sys_params perfectly initialized. The problem - it gets to
                                    bot = new TelegramBot (sys_params.bot_api_key); before it's initialized. The constructor goes first and then goes sys_params initialization (SetupRun(); in main.cpp).

                                    Why do I get to the constructor? I don't instantiate any telebot object at all in the code.
                                    When I get to the constructor I see
                                    sys_params.bot_api_key = <not accessible>
                                    how can it be?

                                      It stops in qstring.h at
                                      inline bool QString::isEmpty()
                                      const { return d->size == 0; }

                                      In addition to @jsulm's excellent points. We don't know the scope of your sys_params (probably "global", yuck, don't do that), and:

                                      typedef struct
                                      {
                                         //some fields
                                          QString bot_api_key;
                                      }SYS_PARAMS;
                                      SYS_PARAMS sys_params;
                                      

                                      We don't know whether you have written anything to the "some fields", or written directly into sys_params.

                                      If I comment out the constructor stuff - I see all fields of sys_params perfectly initialized. The problem - it gets to
                                      bot = new TelegramBot (sys_params.bot_api_key); before it's initialized. The constructor goes first and then goes sys_params initialization (SetupRun(); in main.cpp).

                                      Why do I get to the constructor? I don't instantiate any telebot object at all in the code.
                                      When I get to the constructor I see
                                      sys_params.bot_api_key = <not accessible>
                                      how can it be?

                                      You do if you hit the constructor! And putting a breakpoint there would should you where you do so from.

                                        I see...
                                        In telebot.h I have extern telebot m_telebot;
                                        and in telebot.cpp telebot m_telebot;
                                        in order to work with the object in other parts of the project.
                                        And when I include telebot.h in main.cpp it gets initialized before sys_params is accessible.

                                          Indeed, and that is where it will get instantiated.

                                          Since you say it is m_telebot, is it a member variable in some class? Or is it a (mis-named) global? You will not want it to be a truly global variable. If its constructor requires accessing sys_params, and that needs initialising first at run time (e.g. the SetupRun(); you showed), it is your job to ensure sys_params has been initialised before a telebot is created.
