 # debchroot
-With this **highly configurable bash script** you can enable your 32-bit/64-bit Raspberry Pi, Orange Pi, Arduino UNO, ASUS Tinker Board S R2.0, etc., as well as Android/Harmony OS-based devices (root access required) with ARM architecture support 32-bit/64-bit x86_64 applications, such as every version of **AMPL**, **GAMS**, **Stata**, **TeXmacs**, or **Wine/CrossOver** software with **a single command**. The script creates a minimal Debian/Ubuntu-based chroot in /var/chroot_\<arch\> mirroring your user's home folder and bind-mounting all directories matching '\~/\*', together with the '~/.config/\*' (this allows to run the same app, e.g., Calibre, on different architectures with shared configuration and can be turned off if needed). Technically, you can create multiple chroots, each with a different architecture (so far, one for each architecture), an open filesystem (in contrast to **docker**), and a shared X11 server, including a /var/chroot_arm64 on an x86_64 machine (or /var/chroot_armhf on an x86 one). The apps in chroot are then run with the help of **QEMU** (AMPL, GAMS, Stata, TeXmacs, etc.) and **box86/box64** (Wine/CrossOver) binary format configurations. The **crossover** command allows both binfmt configurations to co-exist, i.e., you can launch your Stata (TeXmacs) and EndNote (or a Steam game) on your device simultaneously with one short command/single click!

-This repository provides several pre-configured versions of the script for these five cases: a) AMPL, b) GAMS, a) Stata (which is, by default, configured with evince as the manual viewer in chroot, please install it in host as well), b) TeXmacs, and c) Wine/Crossover. The AMPL, GAMS, and Stata-specific versions of the script search for files matching '\*ampl\*gz', '\*gams\*exe', '\*stata\*gz\*', and '\*crossover\*.deb' (string case irrelevant) in the user's home directory. If you are interested in using the script, put the script file into **/usr/local/bin/** or **~/.local/bin**, an appropriately-named installer (if required) into **~**, and run these commands in your terminal:
