• Error in compiling x264 on ARM 64-bit platform

  2 septembre 2021, par yanzhang.guo

  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=.

exec_prefix=${prefix}
bindir=${exec_prefix}/bin
libdir=${exec_prefix}/lib

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

     


  


  4. Add file config.h after configure,
