Jessie-> Stretch lib changes - Brian Beuken - 03-08-2018
After the book was written Raspbian Stretch was released (about 2 months after I submitted it, grrr), which is a nice update to the OS, but does mean that libs have changed,
I will adapt all code to work with Stretch, if you are using old Jessie, its time to update as Jessie is now considered to be over.
sudo apt-get update
sudo apt-get upgrade
This won't give you a version of Stretch more of a bit of both worlds, (you need to burn an new SD) but it will give you all new bits you need
you can also do
sudo apt-get dist-upgrade
Which will give you a full upgrade for your current version of Jessie but with the new static libs, and retain all your current files avoiding the need for a full reburn of the SD but with the risk of some legacy libs still in place which may not work as expected now. (though if we're honest a full reburn is the best option here)
The only major complication is that there are now some new libs to use.
- GLESv2_static
- EGL_static
- vchiq_arm
- vcos
- khrn_static
- pthread
pthread is actually used a lot in the book, though the 1st few projects didn't need it, but with the expanded set of libs, pthread is now required also

Buster on non RPi4's also still uses these 5 libs.
If you are using Rpi4 though you need to treat it as a standard X11 system and install mesa-libs and go back to useing GLESv2 and EGL as well as X11... it is however very very important that you point your lib directories at the usr/lib folders and not the usual raspberry opt/vc folders.
