• FFMPEG android compile error

  11 octobre 2017, par Sujith Manjavana

  I’m trying to compile ffmpeg for android using ndk. os:ubuntu 13.10. I followed this tutorial. but when i run the build_android.sh it gives me the following errors-

  sujith@Vaio:~$ cd /home/sujith/ndk9d/sources/ffmpeg
  
  sujith@Vaio:~/ndk9d/sources/ffmpeg$ sudo chmod +x build_android.sh
  
  [sudo] password for sujith: 
  
  sujith@Vaio:~/ndk9d/sources/ffmpeg$ ./build_android.sh
  
  /home/sujith/sujith/ndk9d/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-         x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  here is my build_android.sh

  }

  build_one

  my build_android.sh is located in ffmpeg source root directory.
  how to fix this ? please help me..

• configure : Make require_cc() and require_cpp_condition() functions consistent

  28 mars 2018, par Diego Biurrun

  configure : Make require_cc() and require_cpp_condition() functions consistent
  Their API and implementation is different from other require_foo() functions,
  
  which violates the rule of least astonishment.

• FFmpeg : building example C codes

  23 février 2021, par J. S.

  I have configured and compiled the FFmpeg library using this link :
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

  



  Now, I am trying to build example C codes provided by FFmpeg from here :
https://github.com/FFmpeg/FFmpeg/tree/master/doc/examples

  



  However, when I run make install-examples or make install (suggested by /example/README), I receive this kind of message :

  



  


  make : *** No rule to make target '/doc/examples/README', needed by
 'install-examples'. Stop.

  


  



  I thought this may be due to the rules not being in the correct MakeFile format (I am not sure why they refers to README). How should I go about in fixing this and compiling the example codes ? I have tried to find solutions about this, but there doesn't seem to be much information online.

  



  Thank you.
