      Sorted it with the help of MeduZaPaT.
      I'm going to try to repeat what I did on my other Rpi to make sure I can replicate the fix and I'll document it and put it up here in case anyone else has the same issue I had.

        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.

                      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.
