• x264 Building error - Android

  21 avril 2016, par Jay Parikh

  I am using this repository to build ffmpeg static library which includes x264,libpng and others, please
  visit this link https://github.com/writingminds/ffmpeg-android

  i am using windows 7 as host and ubuntu 15.10 (_64) as guest os using VMware Workstation 12
  and
  Android-ndk-r11b-linux-x86_64

  i do have Prebuilt libraries , but now i want it without PIE support

  i am getting this error in config.log in x264 folder while building
  through

  ./android_build.sh

  here is the log :

  x264 configure script

  ushare is my shared folder between windows and ubuntu

  I have spend almost a week ,trying to solve every error i get.
  these errors are like never ending , 1 solution give 10 more errors
  i have researched a LOT for this library

  thanks a lot in advance.

  Also i thought that x264 library might have poroblem ,so i tried to disable it
  but next library "libpng" also had Same log Error

  i think problem is in Input/output error (obviously)
  this line in log kind of confuses me (those /../../)

  /mnt/hgfs/uShare/ffmpeg-android/toolchain-android/bin/../lib/gcc/arm-linux-androideabi/4.9/../../../../arm-linux-androideabi/bin/ld : fatal error :

  its like two folder overlaping address...

  thanks a lot in advance.
  please don’t go harsh on me ,its my first time,all thanks to this thing...

Appreciate the help.
