Compiling Zink Project
We have got a zink project after creating-zink-project, now it’s time to compile it to EVM bytecode!
# Enter our project
cd my-awesome-project
# Build the project
elko build
# Check the outputs
ls target/zink
my-awesome-project.wasm my-awesome-project.bin
you’ll see a my-awesome-project.bin file under target/zink, and that’s it!
How it works?
first, elko compiles the cargo project to WASM with:
cargo b --target wasm32-unknown-unknown --release
then, there will be some logic inside elko, running wasm-opt for our output
WASM binary
# if you have wasm-opt installed on your machine, you can try the same
mkdir -p target/zink
wasm-opt -O4 target/wasm32-unknown/unknown/release/my-awesome-project.wasm -o target/zink/my-awesome-project.wasm
finally we use zinkc to compile the wasm to EVM bytecode:
# For reproducing it in your command line
zinkc target/zink/my-awesome-project.wasm
mv my-awesome-project.bin target/zink
Future plans (TODO)
- Generate the ABI as well.
- Add command for deploying the bytecode to EVM chain with RPC endpoints.
- Test suite
- …
