Doom Library DSO Compilation

Sat, 26 Nov 2011 17:14:33 | Android Games

Listing 7-25 shows the Makefile for the DSO. It uses the compiler and linker helper scripts agcc and ald, created in Chapter 1. The default optimization level is set to 2. Other compilation flags include the following:

• -nostdinc: Do not include standard header files.

The build targets are as follows:

• lib builds the DSO libdoom_jni.so.

• jni creates the JNI headers for doom.jni.Natives.java and places them in the include folder.

• deploy-lib deploys the DSO to the device using the SDK adb tool.

• clean cleans up the object files.
