Important safety tip
So when you go to redefine the key sequence in Eclipse to do ‘Build
All’ make sure you’re hitting the Ctrl key and not the Shift key. It
explained why I couldn’t define the CXXFLAGS macro in my Makefile.
Instead of Ctrl-X Ctrl-M for build all, I had accidentally defined it
as Shift-X Shift-M. Weird (that it let me), Cool (that I could do it),
but took me a little while to figure out that’s what it was and not
something wrong with my keyboard when Shift-X didn’t do anything 🙂
