If you wish to build paratime binaries yourself, you can use the environment provided as part of the SDK. This way you can also verify that the binaries match the ones running on the network.
The steps below show how to build the test runtimes provided in the
oasis-sdk sources; steps for other paratimes should be similar.
The build environment is provided as a Docker image containing all the necessary tools. Refer to your system's documentation for pointers on installing software.
The runtime sources need to be mounted into the container so prepare a directory first, such as:
git clone https://github.com/oasisprotocol/oasis-sdk.git
The images are available in the
oasisprotocol/runtime-builder repository on Docker Hub and are tagged with the same version numbers as releases of the SDK. To pull the image and run a container with it, run the following:
docker run -t -i -v /home/user/oasis-sdk:/src oasisprotocol/runtime-builder:main /bin/bash
/home/user/oasis-sdk is the absolute path to the directory
containing the SDK sources (or other paratimes - you likely do not need
to download the SDK separately if you're building other paratimes), and
main is a release of the SDK - the documentation of the paratime
you're trying to build should mention the version required.
This gives you a root shell in the container. Rust and Cargo are installed in
/cargo, Go in
/go, and the sources to your paratime are available in
Follow the normal build procedure for your paratime. For the testing runtimes in the SDK, e.g.:
cd /srccargo build --release --target x86_64-fortanix-unknown-sgx
After this step is complete, the binaries will be in
To produce the sgxs format needed on the Oasis network, change directory to where a particular runtime's
Cargo.toml file is and run the following command:
cargo elf2sgxs --release
It is necessary to change directories first because the tool does not currently support cargo workspaces.
The resulting binaries will have the
