## mesa-build.sh
#!/bin/bash

# A simple script to build 64-bit and 32-bit Mesa and vkpipeline-db
# on amd64 Debian testing, Debian unstable, and possibly some Ubuntu
# with some tweaks.
#
# A situation with LLVM on Ubuntu was (is?) not perfect, so you are on your own.
#
# If you do not want to or can not use it, modify the script to install and use
# other LLVM and update LLVMVERSION variable below.
#
# It is too complex to handle fully automatically and be future proof. So just
# edit the script accordingly.
#
# By default only drivers for AMD, Intel and software rendering will be built.
# That will build radeon driver, radv (with ACO and LLVM), llvmpipe, swr,
# lavapipe, and zink, with few other minor things.
#
# No Nvidia drivers will be compiled. This is to speed up compilation
# a bit. Modify COMMON_OPTS to change that.
#
# OpenCL support with clover will be built for 64-bit, but you should know
# the OpenCL support in Mesa still has some bugs, so be aware.
# Valgrind extra support will be built for 64-bit only too.
# Otherwise rest (Mesa, OpenGL, Vulkan, Mesa overlay layer, Mesa device selection
# layer, gallium-nine, zink, lavapipe, vkpipeline-db), will be built for both
# 64-bit and 32-bit versions.
#
# No OpenGL ES (GLES), or EGL will be built. It is simply to save a bit of time
# compiling Mesa. You can enable it in COMMON_OPTS below.
#
# Similarlly a Wayland support is untested, and probably not enabled.
# Modify COMMON_OPTS if needed.
#
# Check variable BUILDDEBUG below to enable also debug builds, which can build
# together with optimized builds.
#
# The build will be performed in ~/mesa-git directory for you.
#
# The source tree will live in ~/mesa-git
# Built libraries and binaries will be in ~/mesa-git/builddir/build-{amd64,i386}-{dbg,opt}/
# Libraries and binaries will be installed into ~/mesa-git/installdir/build-{amd64,i386}-{dbg,opt}/
#
# After compilation is done, the script will perform a small test with glxinfo,
# vulkaninfo and vkcube for 2 seconds.
#
#
# After compilation is done, use '. ~/enable-new-mesa-opt.source'
# (without quotes) in your terminal to enable it.
# You can add it to your ~/.profile or ~/.bashrc file too.
#
# You need to use this '. ~/enable-new-mesa-opt.source' before any other
# OpenGL / Vulkan app is started from the same terminal. It is not enough to
# simply do '. ~/enable-new-mesa-opt.source' in a terminal, and the launch
# steam or some game via desktop shorcut, or other terminal. The changes are
# local to the terminal / shell you used it to. You can use it in many terminals
# as you wish.
#
# Note that `enable-new-mesa-opt.source` will also automatically enable ACO if
# available and enable Vulkan Mesa overlay, Gallium HUD, and DXVK HUD.
# Feel free to modify this script below (line ~280 and ~328) to not do that.
# Or source the `disable-new-mesa-hud.source` script to undo the HUD stuff.
#
# This script will not install libraries system wide, so it is safe to use in
# parallel with your distro libraries. And even have applications using one
# or another, or some using optimized libraries and some using debug libraries.
#
# To get rid of it simply run:
#
# rm -rf ~/mesa-git ~/vkpipeline-db ~/enable-new-mesa-*.source ~/disable-new-mesa-hud.source ~/mesa-{opt,dbg} ~/zink-{opt,dbg}
#
# If you want to use this Mesa's OpenGL / Vulkan for your desktop manager, like
# Gnome Shell, you are on your own, but it can be probably done some way by
# putting needed variables in /etc/environment. Maybe...
# Or tweak INSTALLDIR variable. But few more variables (`-Dprefix` for example)
# will be needed to be changed. See https://www.mesa3d.org/meson.html for details.
#
# Rerunning this script will cleanup builddir and installdirs from scratch,
# so it will take some time.
# If you want a bit faster updates, you can do "git pull", then go into proper
# build subdirectory and recompile, i.e. using:
#  cd ~/mesa-git/builddir/build-amd64-opt/ && ninja && ninja install
