MSYS2 Setup Details - FYI

MSYS2 Install:
• Download and install msys2-x86_64-<Date>.exe (see instructions at
http://www.msys2.org/)
• Install to C:\msys64 (be sure to check 'Run MSYS2 now.' on the last install
dialogue)
• Update package database: pacman -Syu pacman
• Close MSYS2 terminal and launch again MSYS2 MSYS (Shell) from Start Menu
• Update core system packages: pacman -Suu
• Install packages:
  o pacman -S base-devel git wget p7zip
  o pacman -S perl ruby python2 python2-mako mingw-w64-x86_64-toolchain
   • toolchain package options:  ^4-6 (exclude 4 - 6)
  o pacman -S mingw-w64-x86_64-python2-mako
  o pacman -S mingw-w64-x86_64-cmake
  o pacman -S scons
• Update your .bash_profile (setup your PATH)
  o Open .bash profile in your editor (C:\mingw64\home\<user>\.bash_profile

  # Set PATH so it includes MINGW_DIRS if they exists
  MINGW_PATHS=" \
   /mingw64/x86_64-w64-mingw32/bin \
   /mingw64/x86_64-w64-mingw32/include \
   /mingw64/x86_64-w64-mingw32/lib \
   /mingw64/bin \
   /mingw64/include \
   /mingw64/lib \
   "
  MINGW_DIRS=
  for dir in ${MINGW_PATHS}; do
   if [ -d "${dir}" ] ; then          
    MINGW_DIRS="${dir}:${MINGW_DIRS}"
   fi
  done
  export PATH="${MINGW_DIRS}:${PATH}"

• Setup MSYS2 terminal shortcut
  o Navigate to C:\msys\usr\bin and right-click mintty.exe
  o From your context menu, select 'pin to start'
  o In start menu, find shortcut and select 'pin to taskbar'
• OSMesa install script:
  o mkdir -p ~/projects; cd ~/projects
  o git clone https://github.com/trevorsandy/osmesa-install.git
  o mkdir -p osmesa-install/build
• Install script setup
  o mkdir -p /opt/llvm
  o mkdir -p /opt/osmesa
• Execute install script 
  o Launch MSYS2 terminal
  o Select Mingw-w64 64 bit at selection dialogue
  o cd ~/projects/osmesa-install/build
  o ../osmesa-install.sh
• Notes: 
• python2-mako is installed in 2 places, MSYS2 base (/usr/bin) and mingw-w64
(/mingw64/bin)
• Review well the osmesa-insall.sh script to understand the options available
• At script launch, review well the env options output before accepting to
continue execution.
