Incompatible Implicit Declaration of Built-In Function Warning Using NDK with LAME

Question

I\'m trying to follow the tutorial located at the following location

http://developer.samsung.com/android/technical-docs/Porting-and-using-LAME-MP3-on-Android-with-J

Answer 1

After a lot of searching it looks like the answer I was looking for was found here

Lame MP3 Encoder compile for Android

The key for me was to ensure that the following line was added to my Android.mk file

LOCAL_CFLAGS = -DSTDC_HEADERS

as mentioned by James Zhang.

I'm enclosing my complete makefile below this post so what I'm saying is perfectly clear.
