Steps to Compile NTL

Download and extract ntl-5.5.2_android_mod_1.tar.gz (attached)

Download and extract the crystax ndk mod. Use it as your primary NDK library. http://www.crystax.net/android/ndk-r4.php

Edit the makefile headers to fit your system. The GMP options are a bit further down.

Run make all

or

Run

make setup1

make setup2

make setup3

make ntl.a

To run the check routine, run make check

Finally, run make install

Compile string for use with NTL

This won't work with everything, and might contain some unneeded options right now, but it should serve as a good starting point. The variable $NDK_DIR needs to be set to your NDK directory
