Where is the header file of emscripten/bind.h?

Asked 2022-Feb-23 at 14:59

I am using emcc to compile c++ to wasm on Debian 11.
It is successfully done.
So I think emcc knows the path.

But VS Code shows error squiggle under #include because it doesn't know the path to the header file.

Where is the header file?

I'm not familiar to c++ and I install emsdk via git (I just follow the official tutorial here https://emscripten.org/docs/getting_started/downloads.html).

Despite the fact that emsdk is installed, following current (as at 8 Jan '22) documentation will not result in working examples. Build would be failed.

In order to build it on Ubuntu with make --version GNU Make 4.2.1 you need to provide -e option to pass environment variables to make

Then, after build is finished -- start python http server in examples directory and navigate to it in browser: python3 -m http.server 9999 open localhost:9999 and open desired example.

ANSWER

If you don't strictly require Emscripten, you should use Rust's custom WASM support, which is available through the wasm32-unknown-unknown as this is where most of Rust-related WASM development happens.

If you want an example of how to use this target, check out the Rust WASM book.

How to build Ammo.js on Windows?

Asked 2021-May-06 at 09:17

I'm currently trying to build Ammo.js on Windows, following the Instructions in the README. I have

emcc in Path
cmake installed via Visual Studio (C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe)
MinGW installed via Chocolatey

Apparently, because I'm on Windows, cmake could not resolve any paths to the executables in CMakeLists.txt

ANSWER

Answered 2021-May-06 at 09:17

Had two separate Problems here

The MinGw installation from Chocolatey does not include mingw32-make.exe. I uninstalled it, got the MinGW-Installer and proceeded as per this answer: CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles"
I had to actually run cmake --build builds after the first command, which I overlooked in the docs

I ran into this exact issue as well. This is due to Harfbuzz library which is now a dependency for SDL_ttf. Harfbuzz requires make to be installed. There is an open issue on emscripten Github which suggests several workarounds:

Wait for version 2.0.16
modify tools/ports/harfbuzz.py locally with the patch from #13655
Install make on your Windows machine

ANSWER

Answered 2021-Mar-19 at 14:46

Why is this file not found by emcc? Is there an alternate way to handle unordered_maps in C++?

Because it moved to in 2011.

If it is in neither place, you have a very old clang, and it has no unordered_map.

My goal is to compile my C program to wasm with emscripten (which I installed via emsdk). It uses libxml2. I am following the steps outlined here https://github.com/kripken/xml.js/blob/master/script/libxml2 to build libxml2 from source with the appropriate emscripten parameters. When I run emmake make, I get the following warnings and errors:

Easiest way is to resign from shared lib.

There is an important limitation with shared one (side module): it will not work if you are going to use threads in your main application.

So just make a change of ./script/libxml2

Vulnerabilities

No vulnerabilities reported

Install emsdk

This may happen if the system runs out of memory. If you are attempting to build one of the packages from source and are running in a virtual OS or may have relatively little RAM and disk space available, then the build might fail. Try feeding your computer more memory. Another thing to try is to force emsdk install to build in a singlethreaded mode, which will require less RAM simultaneously. To do this, pass the -j1 flag to the emsdk install command.
