Having a problem building Zthread

[indigo0086]

I incorporated the source files and includ path in my project, but when I go to build the project I get following error

include\zthread\Guard.h:494: error: there are no arguments to `isDisabled' that depend on a template parameter, so a declaration of `isDisabled' must be available
include\zthread\Guard.h:494: error: (if you use `-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated)

at this section of code

template <class LockType, class LockingPolicy>
Guard<LockType, LockingPolicy>::~Guard() throw() {
    
  try {
    
    if(!isDisabled())
      LockingPolicy::destroyScope(*this);
    
  } catch (...) { /* ignore */ }  
  
}

NM I found out I have to explicitly define the scope the functions are used in because they are all within template classes. ugh...
