# INSTRUCTIONS
|
#
|
# Prior to running this script you should git-rm the previous content of the
|
# directory pointed to by the "asio" symbolic link, extract the version you
|
# want to integrate and finally, make the "asio" symbolic link point to the
|
# extracted directory. Additionaly, the build environment must be ready; i.e.
|
# you must have sourced "build/envestup.sh" and lunched any target.
|
#
|
# Then, run this script by passing it a list of lunch targets. ASIO will be
|
# minified based on which files were used when building the Parameter Framework
|
# on those lunch targets. As results may very among targets, it is advised to
|
# pass lunch targets of various architectures (ideally, all lunch targets).
|
|
# USAGE
|
# See the usage() function below

This version of ASIO has been minified for lower disk footprint for Android
|
integraton by support/android/asio/asio_shrinker.sh.
|
|
Although unlikely (thanks to having been tested on all AOSP lunch targets), if
|
the Parameter Framework fails to compile on your lunch target because of a
|
missing ASIO header, you may download a vanilla ASIO version from
|
'http://sourceforge.net/projects/asio/files/asio/1.10.6%20%28Stable%29/' and
|
run that script anew.
