      thank you very much for your quick response, but this solution does not work at home, always the same errors at compilation, I have no solutions to mount this core, it lacks references "process_sinc_neon_asm" "convert_float_s16_asm" and "convert_s16_float_asm" at the compilation! what are they related to? mystery!

        @kara what exactly did you do with the solution referenced? can you describe your steps?

        Your problem is no mistery, you are missing compiler flags that should be set by the Makefile.
        Most of us don't have an ODROID to test ourselves so is kind of blind helping :) That's why if you provide more and precise information, the better!

          I will resume step by step this solution and I'll keep you informed, but the first try, it did not work, I do not know much about Retropie compilation despite some basic Unix, I'm a little lost. What flags are you talking about?

              @kara thanks for testing, you will have to be patient for debugging this :)

              I suggest you to start from scratch, can you clone the upstream repository doing exactly this:

              cd $HOME
              git clone https://github.com/libretro/mupen64plus-libretro
              cd mupen64plus-libretro
              

              Now patch the source code doing exactly this (you should just copy/paste the following carefully into the console):

              patch -p1 << "__EOF__"
              diff --git a/Makefile.orig b/Makefile
              index 6d2846c..35c08a3 100644

                   endif
              -else ifneq (,$(findstring odroid,$(platform)))
              -   override platform += unix
               endif
              
               # system platform

                     CPUFLAGS += -mcpu=cortex-a5
              -   else ifneq (,$(findstring ODROID-XU3,$(BOARD)))
              -      # ODROID-XU3 & -XU3 Lite

                     else
              __EOF__
              

              This should get the source patched correctly. Now compile the core using this:

              make platform=odroid WITH_DYNAREC=arm HAVE_NEON=1 FORCE_GLES=1
              

              If it works, then you will have a compiled mupen64plus_libretro.so file. If it doesn't work, please post the log output here so we can take a look. If the log is too big, please use pastebin.

              Once we confirm the right fix, we can fix the scriptmodule later. Good Luck!

                @hhromic thank you for your kindness, I will test all that as soon as I have a little time. I will also post all compilation results of modules that do not install on odroid xu4.

                  I'm not as good as you in linux, I do not know how to make a paste of windows to linux odroid, I went through a text file with a chmod + x, I executed the script, it makes me mistakes (patch unexpectedly ends in middle of line), can you just tell me what are the lines to change in the MakeFile? it will be faster!

                    everything seems obvious to you but for someone like me who is not familiar with the linux system, it's really hard to understand all that, even if I know a little programming !

                      @kara relax, don't panic. I'm trying to help you here. No need to be rude, i.e. I'm not as good as you in linux or everything seems obvious to you.

                      As you are trying to compile things from source, I assumed you had some minor experience with linux, sorry for that.

                      Anyway, after cloning the repository, you edit the Makefile file in the top-level directory and remove these lines (should be lines 33 and 34):

                      else ifneq (,$(findstring odroid,$(platform)))
                         override platform += unix
                      

                      Then, further down find these lines (should be lines 185 and 186):

                         else ifneq (,$(findstring ODROID-XU3,$(BOARD)))
                            # ODROID-XU3 & -XU3 Lite
                      

                      And replace them with these lines:

                         else ifneq (,$(findstring ODROID-XU,$(BOARD)))
                            # ODROID-XU3 & -XU3 Lite and -XU4
                      

                      The patch I posted before says exactly this. Lines starting with - mean what to remove and lines starting with + indicate what to add in their place. The numbers between @@ indicate where to find these lines in the file to be modified.

                      Don't forget that this is an untested patch (you are testing it!) so hopefully it works for you, and if that is the case we can fix it for everyone. Otherwise we keep investigating.

                        I apologize. I'm just a little stressed, I would like to build a recent image of Retropie that works, and my weak knowledge makes me panic sometimes. All of my apologies. Thank you in any case for your patience and your precious help!

                          The compilation of glsm is not done, many errors, many undeclared variables

                          custom/glsm/glsm.cpp: In function 'void bindFBO(GLenum)':
                          custom/glsm/glsm.cpp:251:7:error: 'glBindFramebuffer' was not declared in this scope
                          glBindFrameBuffer(GL_FRAMEBUFFER, gl_state.framebuf[0].desired_location)

                          ...

                            @kara can you try to compile with this:

                            make platform=unix-odroid WITH_DYNAREC=arm HAVE_NEON=1 FORCE_GLES=1

                                @kara can you post the full output log somewhere?
                                Maybe you are missing the opengl libraries in your system.

                                  @kara can you try these commands:

                                  apt-get --assume-yes remove libgles2-mesa-dev
                                  apt-get --assume-yes install libgles2-mesa-dev
                                  apt-get --assume-yes remove libgles1-mesa-dev
                                  apt-get --assume-yes install libgles1-mesa-dev
                                  

                                  And if they installed new packages, try again with the original make invocation (without "unix-" and just "odroid").

                                      Can you confirm me you used the following command in the successful build?

                                      make platform=odroid WITH_DYNAREC=arm HAVE_NEON=1 FORCE_GLES=1

                                          @kara now that we know how to fix the compilation, we need to fix it upstream.

                                          Can I ask you to test compilation of new mupen64plus core as well?

                                          I setup a patch in my github, just follow these directions:

                                          cd $HOME
                                          git clone -b fix-odroid https://github.com/hhromic/mupen64plus-libretro-nx
                                          cd mupen64plus-libretro-nx
                                          make platform=odroid WITH_DYNAREC=arm HAVE_NEON=1 FORCE_GLES=1
                                          

                                          Once that is confirmed I will help you send the fix upstream.

                                            bravo, you're good, very nice to meet people like you, I tested these lines, it works well! Tell me, the warnings at compilation are important? There are some, but the compilation is complete without errors! and I have my .so file
