Question

I have successfully integrated and compiled ffmpeg with libfaac. When I am trying to compile libfaac functions I’m getting this error:

/home/admin1/Desktop/android/workspace/.../obj/local/armeabi/libavcodec.a(libfaac.o): In function `Faac_encode_close':
/home/admin1/Desktop/android/workspace/.../jni/ffmpeg/libavcodec/libfaac.c:145: undefined reference to `faacEncClose'

collect2: ld returned 1 exit status
make: *** [/home/admin1/Desktop/android/workspace/.../obj/local/armeabi/libxyz.so] Error 1

I have no idea why I’m getting this error.

Any help would be appreciated…

I solved it using Android.mk‘s LOCAL_LDLIBS…

I forgot to add a reference to my libfaac.a file in Android.mk:

LOCAL_LDLIBS := -ldl -lgcc -llog -lz -lm -lc -lstdc++ -L$(LOCAL_PATH) -lfaac
