cadence_movevm

An investigation into using MoveVM within Go for the purpose of Cadence compilation.

Dependencies

This repo requires a local version of https://github.com/RZhang05/aptos-core/tree/composite-cadence in the same parent directory as this repo as specified in lib/sample/Cargo.toml.

Build

This repo consists of a main Go library which calls into a nested Rust library which calls into a nested Go library. This means that there are some complications with linking and the build process. This was built on linux.

1. The innermost Go library cannot be static because this will cause multiple definition errors in the linker for cgo functions.

Mac

Changes required

• replace libsample.so with libsample.dylib in the Makefile
• potentially build go_lib first, the Makefile should handle this
• copy libmain.dylib to the root directory
