This project contains scripts and patches to cross compile and package packages for
the [Termux](http://termux.com/) Android application.
* Install the Android SDK at `$HOME/lib/android-sdk`. Override this by setting the environment
variable `$ANDROID_HOME` to point at another location.
-* Install the Android NDK, version r10e, at `$HOME/lib/android-ndk`. Override this by setting
+* Install the Android NDK, version r11, at `$HOME/lib/android-ndk`. Override this by setting
the environment variable `$NDK` to point at another location.
Alternatively a Dockerfile is provided which sets up a pristine image

These differs from glibc ones in that
-1. They are not preprocessor #define:s so cannot be checked for with #ifdef RTLD_GLOBAL (dln.c in ruby does this)
+1. They are not preprocessor #define:s so cannot be checked for with `#ifdef RTLD_GLOBAL`. Termux patches this to
+ #define values for compatibility with several packages.
2. They differ in value from glibc ones, so cannot be hardcoded in files (DLFCN.py in python does this)
-3. They are missing some values (RTLD_BINDING_MASK, RTLD_NOLOAD, ...)
