First, generate the JNI headers for
opengl.jni.Natives.java
with the following:
$ make jni
Next, compile the library with the following:
user@ubuntu:~/workspace/ch05.OpenGL/native$ make
agcc -Wall -O2 -fpic -c -DNORMALUNIX -DLINUX -DANDROID -
I/home/user/mydroid/frameworks/base/opengl/include cuberenderer.c
