The build script requires the paths to the NDK and OpenSSL sources. It runs the build in a Docker container, by default. But if the required tools are installed on the system (currently jq, make and perl) it can also be run directly on the system by defining NO_DOCKER. A relatively recent version of the NDK is required (the pre-built toolchains are required).

# Build OpenSSL's libcrypto for use in strongSwan's Android app. Requires
|
|
# passing the path to the Android NDK as well as that to the OpenSSL sources,
|
|
# for instance:
|
|
#
|
|
# ANDROID_NDK_ROOT=~/android-ndk OPENSSL_SRC=~/openssl ./build.sh
|
|
#
|
|
# The files are written to the jni/openssl directory of the app, by default, but
|
|
# that can be changed via $OUT variable.
|
|
#
|
|
# Setting $NO_DOCKER disables the use of Docker (requires the necessary build
|
|
# tools on the system), otherwise, setting $TAG allows using a custom tag for
|
|
# the Docker image.
