Error in compiling x264 on ARM 64-bit platform

Question

The same x264 source code I compiled on Debian 10 (Buster) system has no problem, but I can't compile it on an ARM 64-bit platform. Why?

Maybe there is something wrong with the Makefile, but I don't know where it is.

1. Configure

   ./configure --disable-asm --enable-shared  --host=aarch64-linux
   
   platform:      AARCH64
   byte order:    little-endian
   system:        LINUX
   cli:           yes
   libx264:       internal
   shared:        yes
   static:        no
   asm:           no
   interlaced:    yes
   avs:           avxsynth
   lavf:          no
   ffms:          no
   mp4:           no
   gpl:           yes
   thread:        posix
   opencl:        yes
   filters:       crop select_every
   lto:           no
   debug:         no
   gprof:         no
   strip:         no
   PIC:           yes
   bit depth:     all
   chroma format: all
   

2. Edit file config.mak,

   SRCPATH=.
   prefix=/usr/local
   exec_prefix=${prefix}
   bindir=${exec_prefix}/bin
   libdir=${exec_prefix}/lib
   includedir=${prefix}/include
   SYS_ARCH=AARCH64
   SYS=LINUX
   CC=aarch64-linux-gnu-gcc
   CFLAGS=-Wno-maybe-uninitialized -Wshadow -O3 -ffast-math  -Wall -I. -I$(SRCPATH) -std=gnu99 -
   D_GNU_SOURCE -fPIC -fomit-frame-pointer -fno-tree-vectorize
   COMPILER=GNU
   COMPILER_STYLE=GNU
   DEPMM=-MM -g0
   DEPMT=-MT
   LD=aarch64-linux-gnu-gcc -o
   LDFLAGS= -lm -lpthread -ldl
   LIBX264=libx264.a
   AR=aarch64-linux-gnu-gcc-ar rc
   RANLIB=aarch64-linux-gnu-gcc-ranlib
   STRIP=aarch64-linux-gnu-strip
   INSTALL=install
   AS=
   ASFLAGS= -I. -I$(SRCPATH) -DSTACK_ALIGNMENT=16 -DPIC
   RC=
   RCFLAGS=
   EXE=
   HAVE_GETOPT_LONG=1
   DEVNULL=/dev/null
   PROF_GEN_CC=-fprofile-generate
   PROF_GEN_LD=-fprofile-generate
   PROF_USE_CC=-fprofile-use
   PROF_USE_LD=-fprofile-use
   HAVE_OPENCL=yes
   CC_O=-o $@
   default: cli
   install: install-cli
   SOSUFFIX=so
   SONAME=libx264.so.157
   SOFLAGS=-shared -Wl,-soname,$(SONAME)  -Wl,-Bsymbolic
   default: lib-shared
   install: install-lib-shared
   LDFLAGSCLI = -ldl
   CLI_LIBX264 = $(LIBX264)
   

3. Make, an error occurred, details in error.

4. Add file config.h after configure,

    #define HAVE_MALLOC_H 1
    #define ARCH_X86_64 1
    #define SYS_LINUX 1
    #define STACK_ALIGNMENT 64
    #define HAVE_POSIXTHREAD 1

    #define HAVE_BITDEPTH10 1
    #define HAVE_GPL 1

Answer 1

I have solved it by running

./configure --disable-asm --enable-shared --enable-static

and modifying at the same time

ASFLAGS= -I. -I$(SRCPATH) -f elf64 -DSTACK_ALIGNMENT=64
