try mac?

I don't have access to Mac at the moment. Do you know why doesn't compile on Windows?

[kevinho]

i think the problem lies in include path in android.mk file, but i am not sure.

You can try these steps -

1. Use NDK android-ndk-r11c
2. Change Android.mk -

      ...................
      LOCAL_SRC_FILES := amr_encoder.cpp \
                amr_decoder.cpp \
                wrapper.cpp
     .....................

N.B.: I guess NDK r10e is capable of compiling if you try step 2, skipping step 1.

My first response was with eclipse by adding the codes inside jni folder and thats why I had to do some changes in Android.mk.

Anyway, to make similar environment as yours, I have downloaded the fresh code again. I have tried your way and without changing a single word anywhere in the code I was able to compile it using Windows 10 64.

1. I didnt add any path variable, also I dont have cygwin as well.
2. I used ndk-build all

Sample command: D:\Users\rajib\Desktop\opencore-amr-android-master\Codec\amr\src\main\jni>D:\DevTools\android-ndk-r10d\ndk-build all

I hope, you can try using ndk-build all and also can check if any other environmental variable is playing this unwanted role.

I get same issue with ndk-build all
Just to clarify,
- I have other projects and they build fine
- I have downloaded the source an have not modified it in any way
- I have tried with android-ndk-r10d and android-ndk-r11c

Ok, it compiles on Linux. Why would that be then? I have no idea about c or ndk but it looks like some path parameter is not compatible with windows
