Thanks David
It seems that a rebuild is the only way. We’ll add that to our instructions then!

Rebuilding our software didn’t correctly rebuild those files that depend on the updated boost files. (I’m using CMake 3.9 with make on Ubuntu 16.04) Checking a bit more carefully it appears that the system .h files are not included in depend.make. I guess this is done to save some time checking all those dependencies as system files are supposed to be relatively stable, but if they’re not, it creates trouble of course. Is there any way to change this behaviour? (ideally something like for one time only, check if dependent system include files are more recent then what was compiled, but that’s a stretch of course).
