ald -o gl-dyn test.o -lgltest_jni -L.

Note
The compiler will complain about the local system JNI headers: “library search path "/usr/lib/jvm/
java-6-sun/jre/lib/i386" is unsafe for cross-compilation.” This message can be ignored.
Finally, the library must be deployed to the device
/data
folder so the activity can load it:
user@ubuntu:~ ch05.OpenGL/native$ make deploy-test
Deploying libgltest_jni.so to /data
adb push libgltest_jni.so /data

As shown in Figure 5-6, when the project is started in the device, two launchers will be placed in the
device desktop: OpenGL Java and OpenGL Native.
