error: 'comp' was not declared in this scope

[Divy Kanungo]

Hi Eljay,

Thanks for reply. Using your proposed solution solved the 
problem of c and comp not being declared in scope. So, is it 
that the new gcc version does not allow directly using the 
protected variabled declared in parent class? (because that 
worked fine when I had gcc 3.4.3)

Also now I have new issues when I compile the program. I get the 
following linker errors:

/usr/local/lib/libbg.so: undefined reference to 
`std::__default_alloc_template<true, 0>::allocate(unsigned int)'
/usr/local/lib/libbg.so: undefined reference to 
`std::basic_streambuf<char, std::char_traits<char> 
>::_M_out_cur_move(long)'
/usr/local/lib/libbg.so: undefined reference to 
`std::basic_string<char, std::char_traits<char>, 
std::allocator<char> >::_Rep::_S_create(unsigned int, 
std::allocator<char> const&)'
/usr/local/lib/libbg.so: undefined reference to 
`std::basic_string<char, std::char_traits<char>, 
std::allocator<char> >::_S_empty_rep_storage'
/usr/local/lib/libbg.so: undefined reference to 
`std::__default_alloc_template<true, 0>::deallocate(void*, 
unsigned int)'
collect2: ld returned 1 exit status

I am not sure why these are appearing. How can solve the above 
problems.

Divy.
