SWIG Native C++ / NodeJS Callbacks
View callback_swig_project.i
// SWIG's %native directive is now supported for JavaScript since SWIG release (4.0.1+)
// This allows us to not only wrap our C/C++ code with ease, but also add our own
// specialized wrapper functionality to our projects - such as callbacks!
//
// Below are three callback implementations shared for convinience (for Node/V8 engines)
// 1. one-off, inline callback
// 2. one-off, async callback
// 3. persistent async callback

Emulating ARM with QEMU on Debian/Ubuntu
View ARMonQEMUforDebianUbuntu.md

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead
