to compile :

• you need ANDROID NDK

make all : build all the programs make install : install all the programs make clean : clean all

to test :

cd 7za make test

look at the makefile to see other tests

III. Debuggable versus Release builds:

In NDK r5, ndk-build has been modified to make it easier to switch between release and debug builds. This is done by using the NDK_DEBUG variable. For example:

$NDK/ndk-build NDK_DEBUG=1 => forces the generation of debug binaries $NDK/ndk-build NDK_DEBUG=0 => forces the generation of release binaries

If you don't specify NDK_DEBUG, ndk-build will keep its default behaviour, which is to inspect the AndroidManifest.xml, if any, and see if its element has android:debuggable="true".

IMPORTANT: If you use the build tools of SDK r8 (or higher), you won't need to touch your AndroidManifest.xml file at all!

       That's because if you build a debug package (e.g. with
       "ant debug" or the corresponding option of the ADT plugin),
       the tool will  automatically pick the native debug files
       generated with NDK_DEBUG=1.

Also, as a convenience, the release and debug object files generated by the NDK are now stored in different directories (e.g. obj/local//objs and obj/local//objs-debug). This avoids having to recompile all your sources when you switch between these two modes (even when you only modified one or two source files).
