x265 dosen't support 'aarch64'
I'd test for including aarch64 in source/CMakeList.txt and modified some compiler options to using '-mtune=native -mcpu=native' for compile source on aarch64 board ( built-in gcc for debian aarch64 ). But it failed to process of linking x265 binary as like this:
[100%] Linking CXX executable x265
libx265.so.165: undefined reference to `x265_cpu_fast_neon_mrc_test'
libx265.so.165: undefined reference to `x265::detect512()'
collect2: error: ld returned 1 exit status
CMakeFiles/cli.dir/build.make:303: recipe for target 'x265' failed
source/common/cpu.cpp exclueded detect512() for arm. -- and -- x265_cpu_fast_neon_mrc_test not included for creating library.
Hope it should be fixed.
Regards, Raph.

hi, Have you solved that problem, which is x265 dosen't support 'aarch64' ? oh, my platform is centos-7.6, aarch64 .
I change the file source/CMakeLists.txt ,add ‘aarch64’ param as follow:
set(ARM_ALIASES armv6l armv7l aarch64)
then make ,there are errors:
[ 1%] Building CXX object encoder/CMakeFiles/encoder.dir/analysis.cpp.o
c++: error: unrecognized command line option ‘-mfloat-abi=hard’
c++: error: unrecognized command line option ‘-mfpu=neon’
c++: error: unrecognized command line option ‘-marm’when I change ource/CMakeLists.txt file ,
if(CPU_HAS_NEON)
238 set(ARM_ARGS -march=aarch64 -mtune=native -mcpu=native -fPIC)
239 add_definitions(-DHAVE_NEON)it is also error,
