The error in the ticket mentions srand. What I do is google srand and I
get e.g.
http://www.cplusplus.com/reference/clibrary/cstdlib/srand/
it says it is in cstdlib, so add
#include <cstdlib>
to the cpp file that is having a problem. Then likely another file
will have the same problem due to the same or another missing header,
and after a few iterations of this the problem should be solved. Most
likely all the missing includes are in cpp files, though it is
possible that a header might miss something too. The problem is caused
by older versions of GCC having header A also pull in header B without
the standard saying that it should do so (which is allowed but
unfortunate). The newer version of header A in a newer GCC then stops
pulling in header B, and suddenly it becomes apparent that header B
should have been included where A was also included, but before it was
invisible that this should have happened.
Cheers
