emscripten

问题 I want to build bananabread c++ project with emscripten. I added BINARYEN_ROOT intro ./emscripten . I also build BINARYEN. LLVM_ROOT = '/Volumes/POMOCNI/WWW-HTDOCS/emsdk-demos/emsdk/emsdk/fastcomp/bin' EMSCRIPTEN_ROOT = '/Volumes/POMOCNI/WWW-HTDOCS/emsdk-demos/emsdk/emsdk/fastcomp/emscripten' EMSCRIPTEN_NATIVE_OPTIMIZER = '/Volumes/POMOCNI/WWW-HTDOCS/emsdk-demos/emsdk/emsdk/fastcomp/bin/optimizer' NODE_JS = '/Volumes/POMOCNI/WWW-HTDOCS/emsdk-demos/emsdk/emsdk/node/12.9.1_64bit/bin/node'

问题 I am learning about emscripten and trying to understand it better. As far as I understand the use-case it was mostly designed for is to port existing C/C++-code to a web client (browser) and calling C/C++ code from JavaScript. But I am wondering whether it is possible to use C++ and Emscripten to web page (note: this is more out of curiosity - I know that there are not many good reasons to do that at the moment). I manage to call Javascript functions from C++ and pass arguments of types

问题 Is it possible to export a Standard ML function such as fun fac 0 = 1 | fac n = n * fac (n - 1); To a respective JavaScript function, via Emscripten? I know the compilation can be done, but I'm not sure how exactly you would access "fac" from JS code. 来源： https://stackoverflow.com/questions/20918629/how-to-export-standard-ml-functions-to-javascript-via-emscripten

问题 Can I somehow create a wasm file, that will work on its own as described in MDN here (by instatiating the objects and calling functions on them)? All the guides I can find (such as this one on MDN) recommend using emscripten; that will, however, also include ~70kB "glue code" (with ~50 kB optional filesystem emulation), that has additional logic (like detection node/browser environment and automatic fetching etc), and probably some other emulation. What if I don't want that "glue code" and

问题 I've been struggling to port a simple C program that uses SDL2 for graphics to the web using emscripten. I scanned through example programs but was unable to find one that draws to the screen using SDL_RenderDrawPoint, SDL_RenderDrawLine, or SDL_RenderDrawRect. These functions work on the windows/ubuntu versions of my program, but not on the emscripten version. I simply see the screen painted with the cleared color, but nothing drawn to it. Here's sample code that showcases the issue.

问题 I'm rendering the same scene using the same exact C++ code, once to native OpenGL on windows and once using Emscripten to WebGL. Everything in the scene looks exactly the same, except when I'm rendering something with alpha != 1.0. The difference looks like this: The blue cube color is (0.0, 0.0, 1.0, 0.5) The shader used for rendering the cube does nothing except draw the color. On the right is how it looks with OpenGL and is the expected result, just blue with half transparency. On the left

问题 As you can read here: https://forum.vuejs.org/t/wasm-how-to-correctly-call-a-webassembly-method-in-vue-js/83422/24 I'm trying to figure out how to import a module generated by emscripten in Vue.js in order to call its methods. Following the indications found here: How load an emscripten generated module with es6 import? I compiled add.c with this command: emcc add.c -o js_plumbing.js -s EXPORTED_FUNCTIONS="['_Add']" -s EXTRA_EXPORTED_RUNTIME_METHODS=['ccall','cwrap'] -s EXPORT_ES6=1 -s
