can't make wasm

[vaaaaanquish]

Hi. I couldn't get WASM to work.

In local OSX.

$ docker pull emscripten/emsdk
$ docker run -it emscripten/emsdk bash

In Container.

$ em++ --version

$ git clone /~https://github.com/facebookresearch/fastText.git

Is there a docker image or something that guarantees that master can build?

[vaaaaanquish]

emsdk version seems to be the cause.

In the docker container, I ran the following. So it worked.

$ git clone /~https://github.com/emscripten-core/emsdk.git
$ cd emsdk
$ ./emsdk install 1.39.12
$ ./emsdk activate 1.39.12
$ source "/src/emsdk/emsdk_env.sh"

$  em++ --version

$ ls webassembly/
README.md  doc	fasttext.js  fasttext_wasm.cc  fasttext_wasm.js  fasttext_wasm.wasm

I'm trying to figure out which specific feature updates are causing the problem...

[vaaaaanquish]

We explored. Does not work emsdk>=2.0.4

• emsdk=="2.0.3" : success
• emsdk=="2.0.4" : faild

[vaaaaanquish]

It looks like the following.

• Stop including malloc and free by default. If you need access to them from
  JS, you must export them manually using
  -s EXPORTED_FUNCTIONS=['_malloc', ..].

emsdk release note: https://emscripten.org/docs/introducing_emscripten/release_notes.html

[loretoparisi]

We explored. Does not work emsdk>=2.0.4

• emsdk=="2.0.3" : success
• emsdk=="2.0.4" : faild

I confirm that doing

./emsdk install 2.0.3
cd ..
cd fastText
make clean
make wasm

it works!

[searleser97]

Does anyone know What would be the modification to the Makefile in order to be able to use the latest version of emscripten ?

[vaaaaanquish]

Perhaps, it need to add an -s EXPORTED_FUNCTION Makefile
/~https://github.com/facebookresearch/fastText/blob/master/Makefile#L76

[vaaaaanquish]

@searleser97 @loretoparisi @Celebio Thx for response. #1227 solved the problem.

[loretoparisi]

@vaaaaanquish welcome, btw I put the pre-built WASM here in FastText.js

[vaaaaanquish]

@loretoparisi Great works!
It would be nice to have a link in the documentation
