This page was last modified on Feb 23, 2023 by MDN contributors. Let's start with the same simple C example as the last time: To compile it, we use latest Emscripten and pass a -g flag, just like in the original post, to include debug information: Now we can serve the generated page from a localhost HTTP server (for example, with serve), and open it in the latest Chrome Canary. Let's resume execution a few times and we can see how the inner x is changing as well-either by looking in the Scope view again, adding the variable name to the watch list, evaluating it in the console, or by hovering over the variable in the source code: From here, we can step-in or step-over C++ statements, and observe how other variables are changing too: Okay, so this all works great when a debug information is available, but what if we want to debug a code that wasn't built with the debugging options? Theoretically Correct vs Practical Notation, Centering layers in OpenLayers v4 after layer loading. I have no idea if I am using Firefox 52 on the Windows XP operating system.

Uncaught (in promise) TypeError: WebAssembly Instantiation: Import #0 module="env" error: module is not an object or function. The quickest, most efficient way to fetch a wasm module is using the newer WebAssembly.instantiateStreaming() method, which can take a fetch() call as its first argument, and will handle fetching, compiling, and instantiating the module in one step, accessing the raw byte code as it streams from the server: If we used the older WebAssembly.instantiate() method, which doesn't work on the direct stream, we'd need an extra step of converting the fetched byte code to an ArrayBuffer, like so: The WebAssembly.instantiate() function has two overload forms the one shown above takes the byte code to compile as an argument and returns a Promise that resolves to an object containing both the compiled module object and an instantiated instance of it.

Maybe there is a setting or permission you can turn on? First of all, if you used raw WebAssembly debugging before, you might notice that the entire disassembly is now shown in a single file-no more guessing which function a Sources entry wasm-53834e3e/ wasm-53834e3e-7 possibly corresponds to.
