• FFmpeg compile for Android (configure, make)

  11 août 2013, par manutd

  I want to compile ffmpeg for Android ver.
  But everytime I try, I can't compile the source of ffmpeg.
  I think my configuration option may be invalid.

  I used this script for configure.

  #!/bin/sh
  
  NDK_PATH=$HOME/android-ndk-r8
  
  PREBUILT=$NDK_PATH/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86
  
  
  
  LDFLAGS="-Wl,-T,$PREBUILT/armelf_linux_eabi.x -Wl,-rpath-link=$NDK_PATH/platforms/android-8/arch-arm/usr/lib \
  
       -L$NDK_PATH/platforms/android-8/arch-arm/usr/lib -nostdlib $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtbegin.o \
  
       $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtend.o -lc -lm -ldl"
  
  COMMON_CONFIG="\
  
            ./configure --target-os=linux \
  
            --arch=arm \
  
            --enable-cross-compile \
  
            --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
            --as=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
            --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
            --sysinclude=$NDK_PATH/platforms/android-8/arch-arm/usr/include \
  
            --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
            --extra-ldflags=\"$LDFLAGS\" \
  
            --extra-cflags=-I$NDK_PATH/platforms/android-8/arch-arm/usr/include \
  
  
  
  eval "$COMMON_CONFIG"
  
  if [ $? -ne 0 ]; then
  
    exit 1
  
  fi

  I have to give compiler a new header file path (by —extra-cflags) because when I typed 'make', compiler didn't know where are header files (like math.h, ctime.h)

  After configure using this scripts and type 'make', I got these error.

  What is the wrong ?
  Does my configuration have wrong info ? or any missing flag ?
