How to detect when you are ready to use functions loaded in asm.js module

Asked 2022-Jan-14 at 19:39

I'm using emscripten to generate a file a.wasm.js that contains functions in C++ for encryption. The webassembly functions take in and return C-strings that hold JSON data. I want to wrap these asm.js functions for more convenient use in my client application. Unfortunately doing it directly inside body.onload doesn't seem to work so I'm using the following hack:

One approach is to define and await a Module.ready Promise. This is injected during Emscripten compilation using the --post-js flag. (see full examples)

Facing problem in compilatoin of C++ code (having dlib and opencv) to WASM

Asked 2020-Nov-27 at 04:12

I am trying to compile the C++ code to WASM but facing problems in it. My C++ code included dlib and OpenCV libraries. I have successfully compiled OpenCV and dlib for C++ environment. Also, I have installed emscripten in my system.

Recently I was facing problems in including the dlib and OpenCV libraries during compilation. So I have asked another question here. Now though I am successfully able to provide header files information. But now I am unable to compile the code. When I am executing the following command:

__builtin_ia32_emms()

ia32 is the name of a x86 architecture. Because of this, I think dlib has no webassembly support. All of the other errors are of the same origin. (Like __builtin_ia32_paddd) I can only guess about the typedef redefinitions. I guess, it's because xmmintrin.h and mmintrin.h were included, although immintrin.h exists.

I have this function "IsBrave" in my main.cpp.
If browser contains navigator.brave it calls the navigator.brave.isBrave() function with await.

But when call from browser's console the exported function, it prints undefined value instead of "Brave" on Brave browser. In other browsers result is "Unknown".

Update progress bar during emscripten webassembly is running?

Asked 2020-Jun-29 at 11:39

I want to show a progress bar during an emscripten webassembly is running. But the progress bar is updatet AFTER the webassembly is finished. Is there a way to either interrupt webassembly (main thread) and then continue or force javascript (main thread) to render the GUI?

main.js

ANSWER

Answered 2020-Jun-29 at 09:49

Unfortunately, it’s not possible to force the UI to render. I don’t know if it’s possible to interrupt wasm, but here comes an alternative idea.

Consider spreading the calculation out over time instead, and give the main thread (and the event loop) some “breathing room” to update the UI.

Let’s say you’re calculating a sum, and it takes a lot of time in total. You can split your calculation so you can calculate a piece of the sum at a time:

emscripten: C functions not "ready" when called asynchronously in Node.js

ANSWER

Answered 2020-Apr-30 at 08:02

Turns out there are two emcc compiler options to disable the asynchronous startup/loading behaviour: -s BINARYEN_ASYNC_COMPILATION=0 and -s SINGLE_FILE=1. This solves the problem for me.

From the related GitHub issue:

In general emscripten tries to do startup asynchronously for wasm, because it's what browsers can best optimize, and worse, Chrome currently has a limitation on the size of synchronous compilations (hopefully will be fixed soon). But you can force sync compilation with -s BINARYEN_ASYNC_COMPILATION=0.

That still leaves fetching the wasm binary file. By default we fetch it asynchronously, but if you have a way to get it yourself before, you can set it on Module['wasmBinary'] and we will just use that synchronously. Alternatively, #5296 will add an option to embed that file, making it available synchronously.
