Emscripten usage issues

[illidanstormrange]

I am using Emscripten to build C++ code for use on the web platform. How can I use Tracy profiler to trace my code?
When I add ZoneScoped directly to the C++ code, the constructor in the Profiler reports an error, The error message is fcntl cannot be used in Emscripten:

    RuntimeError: Aborted(segmentation fault)
    at abort (hello2d.js:754:41)
    at segfault (hello2d.js:316:3)
    at imports.<computed> (hello2d.js:6914:20)
    at hello2d.wasm (hello2d.wasm:0xf891b6)
    at fcntl (fcntl.c:19)
    at hello2d.wasm.tracy::Profiler::Profiler() (http://localhost:…asm-mt/hello2d.wasm)

Looking forward to your answer
