        There's not a problem with the RetroPie's recipe, the last commit in the upstream project has broken the build recipe - doesn't compile on Ubuntu either. We'll how we can fix this - thanks for reporting.

          @mitu seems to be the same kind of problem that we had recently for the lr-scummvm core, where a recent Makefile update very similar to the one reported here broke the linking stage with $(LD). Check the PR I submitted: https://github.com/libretro/scummvm/pull/125

          First, I thought the LD variable was wrongly set to $(CC) instead of $(CXX) for cpp code, but then I realised that the armv conditional was outdated and wasn't setting LDFLAGS correctly.

          Hope that gives some help.

              @hhromic In this case, I think it is wrongly set to $(CC) and linking fails with obvious missing C++ references, since the project mixes C++/C sources. There's no armv platform in the Makefile.libretro and the build fails on x86 Ubuntu also, so I don't think it's related to the architecture. I'll do some more tests.

              EDIT: is there a log page for the libretro buildbot ?

                Yeah man, very similar :o
                There's some temporary fix like lr-scummvm? I can edit .sh file but need some help on your end :D Thx so much

                  @mitu in lr-scummvm which also mixes C/C++ the linker is set to gcc from $(CC) and works now after properly setting -shared -fPIC in LDFLAGS via the armv conditional. You don't need that architecture conditional, but to make sure the LDFLAGS are set correctly somewhere else. Also, note that it won't link with the -Wl,--no-undefined linker option, so you should remove it if it's left there.

                  I also was wondering the same thing but was confirmed to me that it's not public. You can get access to it in the Libretro Discord dev channel.

                    It is fixed already upstream and in RetroPie :) Just update your RetroPie-Setup script and re-compile lr-scummvm. You also will get a newly added option to adjust the mouse speed when using a real mouse.

                      I explained me bad, i've already fixed lr-scummvm, just asking if there's similar method for lr-px68k, but i guess is a no at moment :p

                            @DarishZone ah I see. For the moment better is to wait for mitu to find out exactly how to patch the Makefile. Then it probably will be sent as PR upstream.

                            What you can do in the meantime is to force compilation iwth the previous commit, before it broke. For this, edit the scriptmodule and change the relevant line to this:

                            gitPullOrClone "$md_build" https://github.com/libretro/px68k-libretro.git master c36fafd35094df918f037bea333d7707e656128a

                            Don't forget to revert this temporary fix when all is fixed upstream.

                            Edit Sorry I made a mistake (put master after the hash). Corrected now.

                                  https://travis-ci.org/libretro/px68k-libretro - it looks like it's failing proper. Either removing the -Wl,--no-undefined or compiling with $(CXX) works.

                                    Don't forget to revert this change when @mitu reports back a proper solution later, and before updating RetroPie-Setup again.

                                        ah good to know how to access their CI! In here a dev told me I needed Discord access. Thanks for the tip.

                                        Regarding the candidate fixes, I chose to remove -Wl,--no-undefined (I was setting it in the scriptmodule) together with properly setting LDFLAGS and not rely on re-setting LD. They have been pushing these updates recently to many cores, i.e. standardising to set LD = $(CC) so there are high chances it can get reverted again. So that would be my advice.

                                        Their makefile management is def not ideal ...

                                          The only potential problem if you don't revert it will be when you later update the RetroPie-Setup script. You could get local change conflicts and you will have to resolve them manually, kind of nasty.

                                          However after the fix is done, you don't really need to recompile the core again as the change doesn't touch the source code. So just revert it now and don't compile the core again until the fix is confirmed upstream.
