Usage

Building

Building s2n (Linux Only)

If you are building on Linux, you will need to build s2n before being able to build aws-c-io. For our CRT's, we build s2n at a specific commit, and recommend doing the same when using it with this library. That commit hash can be found here. The commands below will build s2n using OpenSSL 1.1.1. For using other versions of OpenSSL, there is additional information in the s2n Usage Guide.

git clone git@github.com:awslabs/s2n.git
cd s2n
git checkout <s2n-commit-hash-used-by-aws-crt-cpp>

# We keep the build artifacts in the -build directory
cd libcrypto-build

# Download the latest version of OpenSSL
curl -LO https://www.openssl.org/source/openssl-1.1.1-latest.tar.gz
tar -xzvf openssl-1.1.1-latest.tar.gz

# Build openssl libcrypto.  Note that the install path specified here must be absolute.
cd `tar ztf openssl-1.1.1-latest.tar.gz | head -n1 | cut -f1 -d/`
