# Description: This script will configure the MIT Kerberos library
#              for cross-compilation by the Android NDK stand-
#              alone toolchain.
#
# Instructions:
#   1) Download, install, and set up the Android SDK and Android NDK 
#      standalone toolchain.
#           SDK:  http://developer.android.com/sdk/index.html
#           NDK:  http://developer.android.com/sdk/ndk/index.html
#   2) Place this script in the /src directory of the kerberos
#      source directory.
#   3) Run ./autoconf if needed
#   4) Run ./android-configure.sh
#   5) Exclude the following directories by removing or renaming them.
#      NOTE: This script does this automatically.
#           mv ./clients ./clients.exclude   [ kerberos clients ]
#           mv ./tests ./tests.exclude       [ kerberos tests ]
#           mv ./appl ./appl.exclude         [ kerberos applications ]
#           mv ./kadmin ./kadmin.exclude     [ kadmin ]
#   6) Run make
#   7) Install in desired location:
#           make DESTDIR=<staging/path/here> install
#   8) Copy built libraries from staging location to desired 
#      Android project.

## Add Android NDK Cross Compile toolchain to path

## Set up variables to point to Cross-Compile tools

## Export our ARM/Android NDK Cross-Compile tools
export CC="${CCTOOL}gcc"
export RANLIB="${CCTOOL}ranlib"
export AR="${CCTOOL}ar"

## Point these to your cross-compiled CyaSSL library location. CyaSSL can be
## built for Android using the cyassl-android-ndk package or by
## cross-compiling it for Android using yaSSL's shell script (www.yassl.com)
## and the Android NDK Standalone toolchain.
