      @sude Are you cross compiling?
      You should really provide more information about your setup.

          there is no ld folder.

          ld is not a folder but an executable used to link your program. And you don't have installed it - install it with your package manager.

            @jsulm Actually I did not use cross compile and my program features like that.

              You just had to run that command and show its output.
              Anyway if as @Christian-Ehrlicher says you don't have the necessary package installed then that is what you need to address.

                    After you have run the which ld and reported its output.

                    You have not said what OS you are running on, which would help for this question. Assuming you are Ubuntu or something which works similarly, please run this command:

                    locate --regex '/ld$'
                    

                    and show us its output.

                        Maybe a silly question, but did you install build essential package?

                        sudo apt install -y build-essential

                            @sude Just to be sure to understand what's going wrong: do you using your RaspberryPI to build or do you build a PC?

                            Is Qt Creator running on RaspberryPI or on PC?

                                Since your RPi does not have the locate command I suggested earlier, now try:

                                find / -name ld -print 2>/dev/null
                                

                                and show the output (better if you copy & paste the command run plus the output as text than show screen shots).

                                    OK, hold on, that is strange.

                                    which ld shows no ld executable on your PATH.

                                    But the find shows /usr/bin/ld. That should be both executable and on your PATH.

                                    • Output from ls -l /usr/bin/ld?
                                    • Output from echo $PATH?

                                      OK, hold on, that is strange.

                                      which ld shows no ld executable on your PATH.

                                      But the find shows /usr/bin/ld. That should be both executable and on your PATH.

                                      • Output from ls -l /usr/bin/ld?
                                      • Output from echo $PATH?

                                        @sude

                                        pi@raspberrypi:~ $ ls -l /usr/bin/ld
                                        toplam 0
                                        

                                        I don't understand. The output should look something like mine under Ubuntu:

                                        ls -l /usr/bin/ld
                                        lrwxrwxrwx 1 root root 19 Oct 20 12:09 /usr/bin/ld -> x86_64-linux-gnu-ld
                                        

                                        Since it's a soft link on mine and may be on yours, now try:

                                        ls -lL /usr/bin/ld
                                        -rwxr-xr-x 1 root root 1740384 Oct 20 12:09 /usr/bin/ld
                                        

                                        on yours, please?

                                        It is zero how can i echo :(

                                        What is zero? On mine:

                                        echo $PATH
                                        /home/jon/.local/bin:/home/jon/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

                                          @sude said in :-1: error: collect2: fatal error: cannot find 'ld':

                                          pi@raspberrypi:~ $ ls -l /usr/bin/ld
                                          toplam 0

                                          Ah, hang on, that is indeed what you get if /usr/bin/ls is an (empty) directory:

                                          mkdir empty
                                          ls -l empty
                                          total 0
                                          

                                          Maybe toplam means total in your language?!

                                          OK, that is indeed strange. /usr/bin/ld should be, or be a soft link to, an executable file, not a directory!

                                          Go back to the find command. Assuming RPi find accepts -ls, try:

                                          find / -name ld -ls 2>/dev/null
                                          

                                          If not try:

                                          ls -ld `find / -name ld -print 2>/dev/null`
                                          

                                          Note those two ` ("backtick") characters, you will have to find that on your keyboard.
