Teaclave SGX SDK v2.0 preview

Teaclave SGX SDK v2.0 is a revamped version. It is much more developer friendly compared to v1.1.

• supports cargo build + no_std, xargo build and cargo-std-aware mode.
• Tokio and Tonic is directly available to enclave programming without any change.
• Refactored Intel's SDK using Rust. Only a small portion of Intel's SDK is required.
• Improved testing framework. sgx_tstd is well tested now.
• No need to maintain 100+ 3rd party dependencies. Most dependencies are use-able without any change.

Build system

We still maintain the legacy no_std cargo build support, and xargo build with a customized sysroot. v2.0 supports cargo-std-aware as well.

To switch from these build modes, please specify

• BUILD_STD=no to use traditional no_std cargo build
• BUILD_STD=cargo (default setting) to use the new std aware cargo build
• BUILD_STD=xargo to use xargo build

We are still working on porting all v1.1 samples to v2.0. Current available samples include:

• backtrace

• crypto
• hellworld
• httpreq
