openssl_build.md

OpenSSL doesn't have cmake project by default, so we use ssl.cmake to integrate OpenSSL build with cmake.

Build openssl from downloaded source archive

mkdir build && cd build
cmake .. -DTIM_VX_ENABLE_TENSOR_CACHE=ON -DBUILD_OPENSSL=ON

Build openssl with local source repo

git clone git@github.com:openssl/openssl.git ${local_ssl_repo}
# checkout to 1.1.1t or other release tag
# build tim-vx with local ssl source repo
mkdir build && cd build
cmake .. -DTIM_VX_ENABLE_TENSOR_CACHE=ON -DBUILD_OPENSSL=ON -DLOCAL_BUILD=ON -DLOCAL_OPENSSL=${local_ssl_repo}

Build openssl with android-ndk

cmake .. -DTIM_VX_ENABLE_TENSOR_CACHE=ON -DBUILD_OPENSSL=ON -DLOCAL_BUILD=ON -DLOCAL_OPENSSL=${local_ssl_repo} -DCMAKE_TOOLCHAIN_FILE=${ndk_root}/build/cmake/android.toolchain.cmake -DANDROID_ABI=arm64-v8a -DCROSS_ANDROID=ON -DEXTERNAL_VIV_SDK=${ANDROID_OVX_DRV_PREBUILD}
# change ANDROID_ABI accroding to target platform

Build openssl with mirrored ssl.cmake

If ssl.cmake not always accessable from your originization, you can mirror it and replace the download url by append -DOPENSSL_CMAKE_URL=<ssl.cmake mirror> to cmake command line.

Deployment with OpenSSL libraries

All libraries can be installed in single place by

make install # will install all required library(libtim-vx, libssl, libcrypto) to <build>/install/lib/

TODO: General cross build with openssl not support yet
