Compiling Solang to WebAssembly

Open v1rtl opened this issue 4 years ago • 21 comments

Hello, I'm writing a Deno library for Solidity compiler bindings and I decided to try to wrap Solang.

I am following this guide for compiling Rust to WebAssembly: https://depth-first.com/articles/2020/06/29/compiling-rust-to-webassembly-a-simple-example/

my linux kernel version is 5.10.63, distro is Manjaro Linux

I installed lld, lib32-llvm, libc++, rustc 1.53, rustup 1.24.3

and added this to Cargo.toml:

[dependencies]
getrandom = { version = "0.2", features = ["js"] }

and tried to run cargo build --target wasm32-unknown-unknown --release

and I get this:

What should I install from C/C++ libraries to make it compile?

thanks in advance

I think solang should be compiled to wasi, like so:

cargo build --target wasm32-wasi --release

Then again I don't know if node and/or browsers support wasi.

If I try that, I just get an error about llvm not being found: the llvm libraries needs to built for wasm first. I've tried to do this with clang and failed, I was going to do this with emscripten next.

Also @talentlessguy thank you for looking at porting solang to webassembly, this is really needed :smile:

seanyoung avatar Sep 24 '21 11:09 seanyoung

@seanyoung

  1. Yes there's wasi in Node.js and std/wasi in Deno

error: build failed

for more context:

I have:

  • gcc 11.1.0
  • llvm 12.0.1-4

v1rtl avatar Sep 24 '21 11:09 v1rtl

So there are two issues:

  • clang needs the wasi sdk. Copy this into your clang directory and add --sysroot=wasi-sysroot.. using TARGET_CFLAGS and TARGET_CXXFLAGS
  • inkwell needs a little patch, working on that

seanyoung avatar Sep 24 '21 15:09 seanyoung

With that done a whole new world of pain is opened: linking. This requires a wasm build of llvm which can be done with emscripten, I think. I don't have it working yet.

seanyoung avatar Sep 24 '21 15:09 seanyoung

@seanyoung It still errors:

I have clang and wasi-sdk both installed to /usr/bin

v1rtl avatar Sep 24 '21 15:09 v1rtl

You need to set the correct sysroot for the wasi sdk (share/sysroot in wasi-sdk).

inkwell needs this fix: https://github.com/TheDan64/inkwell/pull/270

seanyoung avatar Sep 24 '21 15:09 seanyoung

@seanyoung oops sorry I found out the location of sysroot it was in /opt/wasi-sdk

but now I get this:

/opt/wasi-sdk/wasi-sysroot
➜ env TARGET_CFLAGS=--sysroot=$WASI_SDK_PATH TARGET_CXXFLAGS=--sysroot=$WASI_SDK_PATH cargo build --target wasm32-wasi --release

error: build failed

this is wasi-sdk v12.0-1

v1rtl avatar Sep 24 '21 16:09 v1rtl

Ok, now the issue is that you are using your systems llvm, so compiled for x86, not an llvm cross-compiled to wasm. That can be done with emscripten (I hope).

seanyoung avatar Sep 24 '21 16:09 seanyoung

@seanyoung do you know how to do that?

I have both emscripten, llvm and wasi-sdk installed. I also have wasm-ld

v1rtl avatar Sep 24 '21 16:09 v1rtl

I haven't gotten it working yet. Any help would be appreciated.

seanyoung avatar Sep 24 '21 16:09 seanyoung

I think we need this resolved. https://github.com/rustwasm/wasm-pack/issues/654

Then again, others have compiled clang to run in a browser - which means wasi is not necessary.
