        This is awesome!

        How difficult would it be to add support for the howler?

        The software was written in C and the source is available on github already.
        https://github.com/wolfwaretech/Howler-Arcade-Controller-Firmware

        would love to be able to use the controller I have rather than have to buy a new one.

        Keep up the good work.

          I'm trying to install LEDSpicer using the latest Retropieimage on a Raspberry Pi.
          I am at the part where it says
          ./configure CXXFLAGS='-s -O3' --prefix=/usr --sysconfdir=/etc
          it goes all the way through it OK but right at the end I get
          configure: error: tinyxml2 not found.
          Now I can see you need version 6, but I can only get version 4, so I assume that is why I'm getting the error?
          I can't figure out how to install version 6.
          I've been looking all over the net for a solution for hours and I'm completely stuck.
          My knowledge of Linux is pretty basic, so as detailed a response as possible would be much appreciated ;)
          TIA

            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:

                  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.

                            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.
