• Compiling x264 on a Mac : "No working C compiler found" and "arm-linux-androideabi-gcc : command not found"

  29 novembre 2014, par Xavi Gil

  I am trying to compile the x264 library for Android, following this post.

  I have cloned the x264 project git clone git://git.videolan.org/x264.git and tried to compile with the following configuration :

  NDK=~/development/android-ndk-r10c    
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
  
  PLATFORM=$NDK/platforms/android-21/arch-arm
  
  
  
  ./configure \
  
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
  --sysroot=$PLATFORM \
  
  --host=arm-linux \
  
  --enable-pic \
  
  --enable-static \
  
  --disable-cli

  The problem is that I get a No working C compiler found. error.

  The conftest.log output :

  $ cat conftest.log 
  
  ./configure: line 153: arm-linux-androideabi-gcc: command not found

  But the arm-linux-androideabi-gcc is the toolchain’s bin folder !!

  Looking at this other question it looks like for some reason, even though the file exists, since it is a 64bit Mac, it won’t execute the arm-linux-androideabi-gcc file and will return this weird error and log.

  I am in a Mac OS X 10.10 and I have installed the XCode Command Line Tools :

  $ xcode-select -p
  
  /Applications/Xcode.app/Contents/Developer

  GCC version :

  $ gcc --version
  
  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

  Can anyone tell me how to fix this please ?

• How to use FFSampledSP to play gsm files

  25 novembre 2014, par QuentinTanioartino

  I am trying to use FFSampledSP on MacOSX but I couldn’t make it working

  These are the steps I executed :

  1. I downloader the jar here :
  2. I added the jar into my build path using eclipse
  3. I downloaded the native library ffsampledsp-universal-0.9.9.jnilib here
  4. I renamed the library to libffsampledsp.jnilib
  5. I put the library into the java.library.path

  Then I tried to play the file with the java audio player developed but without any success

  It fails on

  AudioInputStream pcmStream = AudioSystem.getAudioInputStream(encodedFile);

  This is the error :

  SEVERE: Failed to load native library 'ffsampledsp'. Please check your library path. FFSampledSP        will be dysfunctional.
  
  </clinit>

  Apparently it does not find the ffsampledsp-x86_64-darwin library

  Therefore I tried to import it directly using the following but still without any result

  static 
  
  {
  
      try 
  
      {
  
          System.load("/Users/server/Desktop/libffsampledsp.jnilib");
  
      } 
  
      catch (UnsatisfiedLinkError e) 
  
      {
  
        System.err.println("Native code library failed to load.\n" + e);
  
        System.exit(1);
  
      }
  
  }

  Do you know where the issue is ?
