Need help solving C++ boost compilation error - c++

Question

I am trying to build a sample C++ Circular buffer code but keep running into the issue of declaration of anonymous class must be a definition
The sad part is that I was able to run this code earlier on my Mac but can't do so now, can you suggest can be done to find the root cause.
Compilation
g++ temp.cpp
In file included from temp.cpp:1:

int main(int /*argc*/, char* /*argv*/[])

// insert some elements into the circular buffer
cb.push_back(1);

assert(!cb.full());

// insert some other elements
cb.push_back(3);
cb.push_back(4);
// evaluate the sum

return 0;

It seems that for some reason the definition
template <class T, class Alloc>
class circular_buffer // circular_buffer/base.hpp line 72
/*! \cond */
#if BOOST_CB_ENABLE_DEBUG
: public cb_details::debug_iterator_registry
#endif
/*! \endcond */
{ /* ... */ };
is corrupted. Presumably, you have some macros defined, such as
#define circular_buffer <int>
