ok i found its working now i replace CPUFLAGS in generic ARM with : CPUFLAGS += -DNO_ASM -DARM -Darm -DARM_ASM -D__NEON_OPT -DNOSSE -DARM_FIX -latomic

i able compile to pass the dynaract issue, and i encounter this new issue : /usr/bin/ld: warning: size of symbolstop' changed from 4 in ./mupen64plus-core/src/r4300/r4300.o to 33554432 in ./mupen64plus-core/src/r4300/new_dynarec/arm/linkage_arm.o /usr/bin/ld: ./libretro-common/audio/resampler/drivers/sinc_resampler.o: in function resampler_sinc_process_neon': sinc_resampler.c:(.text+0x80c): undefined reference toprocess_sinc_neon_asm' /usr/bin/ld: ./libretro-common/audio/conversion/float_to_s16.o: in function convert_float_to_s16': float_to_s16.c:(.text+0x90): undefined reference toconvert_float_s16_asm' /usr/bin/ld: ./libretro-common/audio/conversion/s16_to_float.o: in function convert_s16_to_float': s16_to_float.c:(.text+0x1d0): undefined reference toconvert_s16_float_asm' collect2: error: ld returned 1 exit status make: *** [Makefile:1040: parallel_n64_libretro.so] Error 1 ` the issue is as in old thread i discover that the HAVE_NEON condition some how not pass, so i remark it : open Makefile.common and find this string "ifeq ($(HAVE_NEON),1)" and remark the condition. with this all i have successfully build and able to run parallel64 .

note: the convert_s16_float_asm issue only appear if we build with have_neon=1

buld platform="armv neon"

Ah thanks. That would probably help. They really need to fix these issues in the Makefile. I think I did try that and it didn't work for me.

you are using libretro super to build this, try directly clone of this (i mean without using libretro super). then using this command to build for your odroid xu4 make platform="odroid ODROID-XU"

Thanks so much. I'll try that and see if it works.
