The Rust project is compiled as a static library The Go project embeds the Rust library and accesses it with CGO

Pre-requisites

Step 1: Install Golang

  • Install a correctly configured Go toolchain (version 1.21+).
  • Make sure that your GOPATH and GOBIN environment variables are properly set up.

Step 2: Install Rust

Download source code:

# Download sources from github
git clone https://github.com/oligami-0424/ffi-rust-go

# Go to sources directory
cd ffi-rust-go

Build and run binary:

# Build
cargo build

# Run
cargo run

## Build and run Docker container:
```bash
# Build Docker image
docker build -t ffi-rust-go .

# Run Docker container
docker run -it ffi-rust-go /bin/ash
/# ffi-rust-go
:print on rust
Segmentation fault

Run

We have confirmed that it works fine in WSL (Ubuntu), but it does not work well in other operating systems.

On WSL (Ubuntu)

on all Complete program!

On alpine

on all

Go into a Go function and cause a Segmentation fault.

On windows

The moment I call a Go function, it freezes.

on nightly

error: linking with link.exe failed: exit code: 1120 libstd-d9ee307034db292c.rlib(std-d9ee307034db292c.std.e9da0a539f4e1ec4-cgu.0.rcgu.o) : warning LNK4078: multiple '.drectve' sections found with different attributes (00100A00) libffi_go_print.lib(000005.o) : error LNK2019: unresolved external symbol fprintf referenced in function _cgo_beginthread C:\Users\oligami\ffi-rust-go\target\debug\deps\ffi_rust_go.exe : fatal error LNK1120: 1 unresolved externals

I want to move everything normally. Is there any way to do this?

Your confirmation on the OS and input is welcome!
