如何为Android编译OpenSSL 1.1.1

Question

does anyone know or have a script to pre-compile OpenSSL 1.1.1 with Android NDK18 on a Linux machine? This script: https://github.com/david-hoze/build-openssl-android does only work for 1.1.0.h with NDK17b, just switching the numbers doesn't work. BRGDS Marcus

Answer 1

Updated for OpenSSL 1.1.1b / Android NDK R19C:

#!/bin/sh

ANDROID_NDK=~/android-ndk-r19c
OPENSSL_VERSION=1.1.1b

API_LEVEL=23

BUILD_DIR=/tmp/openssl_android_build
OUT_DIR=/tmp/openssl_android

BUILD_TARGETS="armeabi armeabi-v7a arm64-v8a x86 x86_64"

if [ ! -d openssl-${OPENSSL_VERSION} ]
then
    if [ ! -f openssl-${OPENSSL_VERSION}.tar.gz ]
    then
        wget https://www.openssl.org/source/openssl-${OPENSSL_VERSION}.tar.gz || exit 128
    fi
    tar xzf openssl-${OPENSSL_VERSION}.tar.gz || exit 128
fi

cd openssl-${OPENSSL_VERSION} || exit 128
