      No problem:

      ./arm-linux-gnueabihf-g++: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.15, stripped
      

      ok....is it a problem that that says intel and I'm running amd?

        Ok, I think you your problem is, that this toolchain is for 32-Bit PC (i.e. x86), while you are probably running a 64 bit system (i.e. x86_64, you can check with the arch command).

        It might be possible to get this to run, but I'd rather recommend you to get a toolchain that directly runs on your system. you avoid the memory limits of 32 bit architecture with that also.

        So far...

        Qt has to stay free or it will die.

          @aha_1980 Hmm...ok, maybe I missunderstood some of the instruction when it talked about 64bit. I assumed it was talking about the pi, which is 32bit, but yeah it's a brand new Ryzen machine, it's 64 bit.

          I'll have to come back to this later today, but thank you for that. I'll let you know what I find.

            arch command on my desktop:
            x86_64

            the pi:
            armv7l

              Don't worry, as said, cross compiling is advanced stuff ;)

              arch command on my desktop:
              x86_64

              Ok, that proves it.

                If you're following the suggested RaspberryPi2EGLFS guide, in step #10 please pay attention to

                  Ok so I added the options for 64 bit, and looks like it all worked and compiled. So then I went to do the next step which is a test build, but there is no ~/raspi/qt5/bin/qmake

                  That directory doesn't exist, so now I really don't know what the hell to do. The previous steps created the qt5 and qt5pi folders so if there are missing directories, now what?

                    Ok so I got a lot farther using a different set of instructions, in fact I got to actually building in Qt Creator!!

                    However Qt Creator is failing to upload the file to the raspberry pi:

                    mkdir: cannot create directory ‘/opt/widgettest’: Permission denied
                    21:09:40: Failed to upload file "/home/brandon/development/build-widgettest-RaspPi-Release/widgettest".
                    21:09:40: Deploy step failed.
                    Error while building/deploying project widgettest (kit: RaspPi)
                    When executing step "Upload files via SFTP"
                    

                    How do I give Qt permission to do this? Do I need to dissable some security on the pi? Or add "sudo" to some commands in Qt?

                      You should either use credentials for your Pi that allows to write in that folder, or change the folder for something the user you use to connect to your RPi can write to.

                          can you say step by step please..

                          What have you done so far? Any errors you can share here?

                          Just in case, please refer to any of these guides:

                          1. Cross-compile and deploy Qt 5.12 for Raspberry Pi
                          2. RaspberryPi2EGLFS
