      OK here is what I did

      Install tinyxml2 version 4, which is the newest version available in the repos of the pre-built Retropie v4.5.1 image.
      You need this as none of the other versions bellow seem to install the tinyxml2.pc file

      sudo apt install libtinyxml2-dev

      Now change the tinyxml2.pc file to match the version LEDSpicer is expecting

      sudo nano /usr/lib/arm-linux-gnueabihf/pkgconfig/tinyxml2.pc

      Change version to 6.2.0
      Ctrl X and save changes

      Now download and install version 6a of tinyxml2

      wget http://ftp.de.debian.org/debian/pool/main/t/tinyxml2/libtinyxml2-6a_7.0.0+dfsg-1_armhf.deb
sudo dpkg -i libtinyxml2-6a_7.0.0+dfsg-1_armhf.deb

      This version does not update the tinyxml.h file, so install the version bellow which will install an updated version of this.

      git clone https://github.com/leethomason/tinyxml2
cd tinyxml2

      Edit Makefile so that the lib files are installed in the directory LEDSpicer expects to see them.

      sudo nano Makefile

      Change
      prefix = /usr/local
      To
      prefix = /usr

      Change
      libdir = $(prefix)/lib
      To
      libdir = $(prefix)/lib/arm-linux-gnueabihf

      Ctrl X and save changes

      Now install

      make all
sudo make install
cd ..

      Finally delete the old version 4 library files and you should be good start the Installing section on the LEDSpicer without errors

      sudo rm /usr/lib/arm-linux-gnueabihf/libtinyxml2.so.4
sudo rm /usr/lib/arm-linux-gnueabihf/libtinyxml2.so.4.0.1

      It is possible that not all of these steps are needed, but it's the process I went through to get it up and running and it only takes a couple of minutes to do all of this, so you might as well

          I am having a problem with the command:

          sudo service ledspicerd start

          It responds with this error:

          Job for ledspicerd.service failed because the control process exited with error code.
See "systemctl status ledspicerd.service" and "journalctl -xe"

          When I view journalctl -xe this is the error I am greeted with:

          -- Unit ledspicerd.service has begun starting up.

          It looks like I am missing the file with this directory

          /usr/share/ledspicer/.xml

          Thanks in advance.

            Have you tried running ledspicerd -d
            This should tell you if any of the .xml files are missing or if there is an error in the .xml files.

              @12ale you need to set the ledspicer.conf file, that error is maybe the missing colors file.
              you can check the logs also like this:

              cat /var/log/syslog | grep ledspicer

              Use sudo if you get access denied.

                Part of the issue was the missing color files.
                I still get this:

                Job for ledspicerd.service failed because the control process exited with error code.
See "systemctl status ledspicerd.service" and "journalctl -xe"

                When I run ledspicerd -d I get this message:

                Program terminated by error: Missing attribute 'port' inside root

                Thanks for the help.

                  Disregard the previous post. I was able to get everything to work.
                  Thank you for the help.

                    I was kind of giving up hope I would get my Howler working on my Pi3. Is there a retro pi image that I can download that will have everything set up? I'm really new to all of this, and I'm also dyslexic so the amount of reading I have to do is pretty daunting.

                    I'd love to find an image I can just put on my SD card and start going.
