# Example command to build the android target.

##############################################################################

#
|
|
# This script shows how one can build a Caffe2 binary for the Android platform
|
|
# using android-cmake. A few notes:
|
|
#
|
|
# (1) This build also does a host build for protobuf. You will need autoconf
|
|
# to carry out this. If autoconf is not possible, you will need to provide
|
|
# a pre-built protoc binary that is the same version as the protobuf
|
|
# version under third_party.
|
|
# If you are building on Mac, you might need to install autotool and
|
|
# libtool. The easiest way is via homebrew:
|
|
# brew install automake
|
|
# brew install libtool
|
|
# (2) You will need to have android ndk installed. The current script assumes
|
|
# that you are installing it under /opt. If not, you will need to adjust
|
|
# accordingly.
|
|
# (3) The toolchain and the build target platform can be specified with the
|
|
# cmake arguments below. For more details, check out android-cmake's doc.
