For building Wine staging

wine_staging_build.sh

#!/bin/bash

# Builds Wine-staging

# Notes:
# 1. Targeted for usage inside a VM (use shared directory $HOME/mnt/vmshare between host and guest).
#
# 2. For best build, enable WineHQ repository for your Debian flavor, including sources.
#    I.e. in your .sources file for it, have:
#       Types: deb deb-src 
#
#    See also: https://gitlab.winehq.org/wine/wine/-/wikis/Debian-Ubuntu
#
# 3. You'd need to separately push the result on the host to whatever location you want (like to /opt).
#
# 4. Place any manual patches in ${HOME}/build/patches
#
# 5. Override arch to something else if you aren't using Ryzen.
#
# Usage:
# wine_staging_build.sh [staging-patchset]
#
# Examples:
# 1. To build just Wine with ntdll-ForceBottomUpAlloc patches:
#
# wine_staging_build.sh ntdll-ForceBottomUpAlloc
#
# 2. To build specific Wine version with specific patches (matching versions help avoid conflicts);
#
# wine_branch=wine-10.16 wine_staging_branch=v10.16 wine_staging_build.sh ntdll-ForceBottomUpAlloc
#
# 3. wine_ver is a shortcut variable that allows setting aligning version for both:
#
# wine_ver=10.16 wine_staging_build.sh ntdll-ForceBottomUpAlloc
#
# 4. To build full Wine staging:
#
# wine_staging_build.sh
