Problem compiling for wasm #276

Open tanis2000 opened 5 years ago

tanis2000 commented 5 years ago

I'm trying to get tcod-rs to compile for wasm (actually the wasm32-unknown-emscripten target) but I'm getting some errors about the underlying C code and I'm having a hard time finding out the reason why.

I guess there should be a way to tell emscripten to compile libtcod on its own and use that output as the library to link but I'm not sure this is actually happening.

Any help would be greatly appreciated.

Here's the command I'm running to compile my project that has tcod-rs 0.13 as a dependency:

cargo build --target wasm32-unknown-emscripten --verbose

The result is the following output:

tomassedovic commented 5 years ago

Hm, to be perfectly honest, I'd be pretty surprised if libtcod just built for webassembly without any changes. Though I guess it might work with emscripten. I'd start there, building libtcod directly before trying tcod-rs.

It is possible to override a build script:

https://doc.rust-lang.org/cargo/reference/build-scripts.html#overriding-build-scripts

I don't know how that would work (or if it even is possible) with the webassembly backends, though. Actually, I'm not sure how one would build a mix of C and Rust for wasm. I guess llvm can possibly create the object files for both and link that?

I'd definitely be interested in seeing this happen, but I don't have the requisite knowledge or time to do this. If you do get it working, I'd love to see it and would definitely be interested in merging it here!

tanis2000 commented 5 years ago

@tomassedovic I'm lacking time to explore this in the short run as well. I'll have a look at compiling libtcod with emscripten as soon as I can and keep you posted if I have news.

Cheers!

ThibaultLemaire commented 4 years ago

I'm having a similar error on Linux (so we can drop the "on macOS" part in the title).

I'm now trying to build tcod_sys directly with emscripten like so:

export PKG_CONFIG_ALLOW_CROSS=1
export CC=emcc
cargo build --target=wasm32-unknown-emscripten

And I'm hitting this error

I'm afraid what you suggested turns out to be true, @tomassedovic: libtcod itself might need some patching to support compiling on web assembly with emscripten.

FYI, here is my fork where I changed the build.rs a bit to try to compile with emscripten.

tanis2000 commented 4 years ago

@ThibaultLemaire I believe we should put our effort in libtcod if we want to get it up and running either with emscripten or wasm. Apparently it depends on a few functions that aren't in musl. It might be worth trying to get those out of the way to start with, if you've got some time to play around with that.

ThibaultLemaire commented 4 years ago

@tanis2000 Unfortunately, I'm really no expert in C++ and this is about as far as my interest in porting libtcod to webassembly can stretch. There's also the issue of the outdated version of libtcod that tcod-sys is using...

In the end I'd be more interested in translating libtcod to Rust.

tanis2000 commented 4 years ago

Actually a port of libtcod to rust would be really nice. I’ve been thinking about that but it would require quite a lot of work and I really do not have the time for it

tomassedovic commented 4 years ago

Hey @tanis2000 @ThibaultLemaire, before you jump into that, I'd just like to make sure you're aware of doryen-rs:

https://github.com/jice-nospam/doryen-rs

(made by Jice, the original libtcod author IIRC)

and RLTK_RS:

https://github.com/thebracket/rltk_rs

(made by TheBracket, author of Nox Futura).

I have not tried either of them much, personally, but they're both projects in a similar vein, written in pure Rust and they both support compiling to webassembly. Both projects are also actively maintained.

Sorry for not mentioning them earlier, they slipped my mind. But they might be an interesting alternative to look into. I'd actually like to add them to our README as alternatives.

ThibaultLemaire commented 4 years ago

@tomassedovic

before you jump into that

Yeah don't worry I wasn't in that much of a hurry to port libtcod to rust. I can imagine the amount of work that represents.

Jice, the original libtcod author IIRC

Yup, it looks like the guy holds most of the early commits of libtcod

I'd actually like to add them to our README as alternatives

Please do!

I'd just like to make sure you're aware of doryen-rs

Well I'm happy you spared me the trouble of having to search for myself!

I think I'll try to port my roguelike tutorial result to doryen-rs, that'll be fun!

ThibaultLemaire commented 4 years ago

Porting complete!

Here, try the result live!
