Glad to see that my solution in the other thread worked for you. You might want to post that it worked in that thread, so people who find your thread through google know the solution worked. This forum exists for the benefit of everyone.
You're very close actually. You're not declaring the variables wrong, just using them in the wrong way.
If you want to use variables from a base class, even if you have access to them, you must still explicitly say they're in the base class. Like
When I do this for all the Sum variables you access in GrandSum, your code works fine.

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

Hi all!
I am trying to register a device in an existing device class, but I am

Portable Threads Abstraction Classes -
Classes
class SbBarrier
The SbBarrier class implements the 'barrier' multi-thread synchronization technique.
A barrier is a synchronization mechanism that is used for blocking threads as they enter the barrier until a given number of threads are
blocked, at which point all the threads are released again. "
class SbCondVar
A class for synchronizing access to global variables.
Condition variables are used to protect global variables in an environment where multiple threads are running concurrently. "
class SbFifo
A class for managing a pointer first-in, first-out queue.
class SbMutex
A basic class for managing a mutex.
This class provides a portable framework around the mutex interface of the underlying native thread-handling toolkit. "
class SbThreadAutoLock
Simple convenience class for locking access to a function.
This class provides a simple convenience mechanism for automatically locking access to a function that is not re-entrant. "
class SbRWMutex
class SbStorage
The SbStorage class manages thread-local memory.
This class manages thread-local memory. When different threads access the memory an SbStorage object manages, they will receive different
memory blocks back. "
class SbTypedStorage< Type >
The SbTypedStorage class manages generic thread-local memory.
This class manages thread-local memory. When different threads access the memory an SbTypedStorage object manages, they will receive
different memory blocks back. "
class SbThread
A class for managing threads.
This class provides a portable framework around the tasks of instantiating, starting, stopping and joining threads. "
