Android ffmpeg 0.8 compilation issue. not able to create .so files.

[Rajesh]

I am using the following tutorial for ffmpeg compilation . 

http://www.roman10.net/how-to-build-ffmpeg-for-android/

I am followed all the instructions which they have provided. have changed the path in 

**build_android.sh** ,  

i am using android ndk5 and cygwing latest compiler. 

But i am facing following issue. .so file is not gets created .

 

    Krajesh@Rajesh /cygdrive/D/RAJESH-ANDROID/Rajesh-workspace/FFMPEG_2

    $ /cygdrive/d/Android_NDK/android-ndk-r5/ndk-build

    Prebuilt       : libffmpeg.so <= jni/ffmpeg-0.8/android/armv7-a/

    Install        : libffmpeg.so => libs/armeabi-v7a/libffmpeg.so

    install: cannot open `/cygdrive/D/RAJESH-ANDROID/Rajesh-workspace/FFMPEG_2/obj/local/armeabi-v7a/libffmpeg.so' for reading: Permission denied

    /cygdrive/d/Android_NDK/android-ndk-r5/build/core/build-binary.mk:305: recipe for target `/cygdrive/D/RAJESH-ANDROID/Rajesh-workspace/FFMPEG_2/libs/armeabi-v7a/libffmpeg.so' failed

    make: *** [/cygdrive/D/RAJESH-ANDROID/Rajesh-workspace/FFMPEG_2/libs/armeabi-v7a/libffmpeg.so] Error 1

Can any one please explain why i am getting that permission denied issue and how to overcome that . i am using windows 7 pc. 

Thanks.

I have seen permission errors on Windows, and I think they are a result of a bug in NDK5. Have you looked to see if the file it's complaining about has funky Cygwin permissions? Or possibly that libs/armeabi-v7a/libffmpeg.so exists but is write protected?

Hi ,

i have checked that libs/armeabi-v7a/libffmpeg.so  is not write protected. I will switch over to NDK8 and will post my comments.

I also suggested you check the file it was complaining about:

/cygdrive/D/RAJESH-ANDROID/Rajesh-workspace/FFMPEG_2/obj/local/armeabi-v7a/libffmpeg.so

Did you check THAT file to see if it had funky permissions? Did you try
deleting it and rebuilding?
