fastText WASM won't make

I'm following the instructions to generate the WebAssembly module for fastText, and have run into an error in the make wasm step, as described here:

https://fasttext.cc/docs/en/webassembly-module.html

The error is

webassembly/fasttext_wasm.cc:178:9: error: call to deleted constructor of 'fasttext::Meter'
  Meter meter;
        ^
src/meter.h:56:3: note: 'Meter' has been explicitly marked deleted here
  Meter() = delete;
  ^

I'm on OSX 10.15.4. I was able to successfully build and use fastText itself. I'm not very familiar with C or web assembly.

Solution

  • This is a bug that needs to be fixed.

    As a workaround, you can replace Meter meter with Meter meter(false) in fasttext_wasm.cc.

    Thank you for reporting!
