• Getting Error during executin native android code

  3 avril 2013, par dilipkaklotar

  Error on my console

  bash : cannot set terminal process group (-1) : Inappropriate ioctl for device
  bash : no job control in this shell
  Your group is currently "mkpasswd". This indicates that your
  gid is not in /etc/group and your uid is not in /etc/passwd.

  The /etc/passwd (and possibly /etc/group) files should be rebuilt.
  See the man pages for mkpasswd and mkgroup then, for example, run

  mkpasswd -l [-d] > /etc/passwd
  mkgroup -l [-d] > /etc/group

  Note that the -d switch is necessary for domain users.

• arm-linux-androideabi-gcc is unable to create an executable - compile ffmpeg for android armeabi devices

  25 juillet 2013, par Chaitanya Chandurkar

  I am trying to compile ffmpeg for android armeabi devices.
  I am following tutorial by roman10.net
  His given build script builds ffmpeg for armv7-a devices. I want to build it for armeabi.
  

  My ultimate aim is to run ffmpeg commands on android armeabi and armv7-a devices.

  So i change the script's CPU part from

  #arm v7vfpv3
  
  CPU=armv7-a
  
  OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU "
  
  PREFIX=./android/$CPU
  
  ADDITIONAL_CONFIGURE_FLAG=
  
  build_one 

  to

  #arm v6
  
  CPU=armv6
  
  OPTIMIZE_CFLAGS="-marm -march=$CPU"
  
  PREFIX=./android/$CPU 
  
  ADDITIONAL_CONFIGURE_FLAG=
  
  build_one

  (I thought changing it to armv6 would build ffmpeg compatible with armeabi devices. m i wrong ?)

  Doubt 1 :
  Do i also have to change toolchain ?
  i.e from arm-linux-androideabi-4.4.3 to arm-eabi-4.4.0 ?????

  Doubt 2 :

  When i try running ./build.sh (without changing toolchain) it gives me following error :
  

  /home/chaitanya/android/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake,.. blaah blahh blaah

  after that i got lot of warnings saying :
  ‘sub_id’ is deprecated and many other function deprecated warnings.

  platform : ubuntu 11.10
  ffmpeg version : 0.11.2
  NDK : android-ndk-r5b

  Here is my build script :
