I get the following error while trying to compile an Android NDK project:
ndk-build
Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: /home/lamb
Just spent an hour or two trying to figure this one out. Many, many people have had this problem. But as I found out I actually did not have a file name Android.mk it was named Andriod.mk and that was enough to cause me a lot of trouble. Sorry about my original rant but that was the whole problem in the end. I suggest if you have this problem you should check everything until you find something wrong.
This fixed me right up. Thanks guys you put me on the right track anyway.
