    Hi Albert,<br>
    <br>
    Thanks for the replies once again. The 64-bit build I am using is
    available in the BerryBoot SourceForge page here:
<a class="moz-txt-link-freetext" href="https://sourceforge.net/projects/berryboot-updated-images/files/Raspberry-Pi/Testing/Raspberry-Pi-4/">https://sourceforge.net/projects/berryboot-updated-images/files/Raspberry-Pi/Testing/Raspberry-Pi-4/</a>
    (look for the file named
    raspberry_pi_os_buster_arm64_desktop_rpi4_2020.08.20_berryboot.img.gz).
    I actually did not know that the official Raspbian was not yet being
    offered in 64-bit, I simply assumed this was an official release
    image converted for BerryBoot (they use a special type of image
    called Squash FS), but from what I see this is some sort of
    experimental build of Raspbian. I will probably just switch back to
    32-bit until an official 64-bit release comes out.<br>
    <br>
    Many thanks,<br>
    Gilberto<br>

        <div>Unfortunately, that build failed. It's a compile error in
          the DISIS externals which don't seem to be 64-bit-ready on
          ARM, sorry. You can ask Ico to look into this, but for the
          time being I'm afraid that you'll have to switch back to
          Raspbian 32 bit, or compile Purr Data (and fix those compile
          errors) yourself.</div>
        <div><br>
        </div>
        <div>Ico, in case you have the time to look into this, the OBS
          buildlog for 64 bit Raspbian Buster is available here: <a
href="https://build.opensuse.org/build/home:aggraef/Raspbian_10/aarch64/purr-data/_log"
            moz-do-not-send="true">https://build.opensuse.org/build/home:aggraef/Raspbian_10/aarch64/purr-data/_log</a>.
          The error is near the end, but I'm afraid that it won't tell
          you much, because it looks like disis_gpio actually compiles
          alright, but doesn't produce the expected disis_gpio.pd_linux
          binary, probably because the build doesn't know about aarch64
          and misconfigures on that architecture.</div>
        <div><br>
        </div>
        <div> I don't have the time to look into this myself, but if
          either one of you finds a fix, I can deploy it to make the
          aarch64 build go through.<br>

              <br>
              Many thanks for your reply. I have downloaded the .deb
              package for <br>
              Raspbian Buster but I am still having some issues
              installing it. My <br>
              Raspberry Pi is running Buster in arm64 architecture, but
              the .deb <br>
              packages available at the OpenSuse page you linked are for
              armhf only. <br>
              When I try to install it I still get a lot of dependency
              errors. I also <br>
              tried the instructions found in <br>

                rel="noreferrer" target="_blank" moz-do-not-send="true">https://github.com/agraef/purr-data/wiki/Installation#linux</a>

              Raspbian, but at the last step, $ apt install purr-data, I
              get:<br>

              The following packages have unmet dependencies:<br>

              is not installable<br>
              E: Unable to correct problems, you have held broken
              packages.<br>
              <br>
              Would you have any suggestion on how tackle this? I am a
              long time Linux <br>
              user but relatively new to Raspberry Pi and I have no
              experience <br>
              installing packages of different architectures than my
              system's own.<br>
              <br>
              As for the documentation, my apologies for not properly
              checking the <br>
              Wiki page before. I did search for the terms 'Raspberry'
              and 'Raspbian' <br>
              in the main README of the repository and found nothing,
              but I obviously <br>
              should have followed the link for the detailed
              instructions for Linux <br>
              installations (which would have taken me to the Wiki).<br>
              <br>
              Many thanks!<br>
