Build error "fatal error: 'string' file not found" #20

If I try to build according to README (npm install, npm run build), I get the following error on macOS 11.6.2:

docker run --rm -u 501:20 -w /src -v $PWD:/src emscripten/emsdk:3.0.0 emcc -Wall -Werror -g2 -c src/symbol.test.c -o dist/symbol.test.o -I zbar-0.23.90/include/ -I zbar-0.23.90/

Any idea what could be causing this? I tried substituting the emscripten Docker image to use a local emscripten installation, but that fails too, albeit in a different way (unsupported wasm-ld option -retain-symbols-file).

Is there a recommended Node version to build this project? I'm on 16. Xcode command-line tools are installed.

The full build output is attached: build-output.txt

Same here, macOS 12.2

I'd tested on win10 and linux. But I didn't test on Mac. Base on the error, I guess it could be caused by environment variables.
