C++ class is not being included properly.

Hello all,
I have a problem which is either something I have completely failed to understand, or very strange. It's probably the first one, but I have spent the whole afternoon googling with no success, so here goes...
I have a class called Schedule, which has as a member a vector of Room. However, when I compile using cmake, or even by hand, I get the following:
In file included from schedule.cpp:1:
schedule.h:13: error: ‘Room’ was not declared in this scope
schedule.h:13: error: template argument 1 is invalid
schedule.h:13: error: template argument 2 is invalid
schedule.cpp: In constructor ‘Schedule::Schedule(int, int, int)’:
schedule.cpp:12: error: ‘Room’ was not declared in this scope
schedule.cpp:12: error: expected ‘;’ before ‘r’
schedule.cpp:13: error: request for member ‘push_back’ in ‘((Schedule*)this)->Schedule::_sched’, which is of non-class type ‘int’
schedule.cpp:13: error: ‘r’ was not declared in this scope
Here are the relevant bits of code:
#include <vector>
#include "room.h"
class Schedule
{
private:
std::vector<Room> _sched; //line 13
int _ndays;
int _nrooms;
int _ntslots;
public:
Schedule();
~Schedule();
Schedule(int nrooms, int ndays, int ntslots);
};
Schedule::Schedule(int nrooms, int ndays, int ntslots):_ndays(ndays), _nrooms(nrooms),_ntslots(ntslots)
{
for (int i=0; i<nrooms;i++)
{
Room r(ndays,ntslots);
_sched.push_back(r);
}
}
In theory, g++ should compile a class before the one that includes it. There are no circular dependencies here, it's all straightforward stuff. I am completely stumped on this one, which is what leads me to believe that I must be missing something. :-D
