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
I just installed Android-NDK and tried "ndk-build". I had exactly the same error. Here is how I beat it.
bash export NDK_PROJECT_PATH={root_of_android_ndk}/samples/hello-jni ./ndk-build
This worked.
