trouble including ctime in an objective-c++ project

Question

It keeps failing on this kind of message (just replace tm with clock, difftime, mktime, time, asctime, ctime, gmtime, localtime, strftime :

no member named 'tm' in global namespace

I'm linking to an external project (Oolong Engine2) built with a makefile in Xcode 4.2 Does anyone recognize what solutions to this problem may be? I googled a bit and saw that others had the same problem, but saw no solutions.

Answer 1

The answer was something stupid where headers were being included twice.

Answer 2

The issue occurs if headers are included multiple times.

Check if headers are recursive, if yes, make it non-recursive.
