dialogue)
• Update package database: pacman -Syu pacman

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'

• 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.
