Hello,
as part of its interface intrusive_ptr requires the user to supply two functions:
void intrusive_ptr_add_ref(T * p); void intrusive_ptr_release(T * p);
These are called from within the implementation of the intrusive_ptr class. When compiling intrusive_ptr_test, cxx complains that intrusive_ptr uses undeclared functions, because the test includes the header file for intrusive_ptr before declaring those two functions.
Are you sure that the compiler is correct? A dependent unqualified call is resolved at instantiation time.
Hmm, have a look at this: ---%<--- template <class T> struct foo { void bar() { foobar(); } }; void foobar() {} void argl() { foo<int> f; f.bar(); } --->%--- Comeau Online has this to say: ---%<--- "ComeauTest.c", line 2: error: identifier "foobar" is undefined void bar() { foobar(); } ^ 1 error detected in the compilation of "ComeauTest.c". --->%--- What do you think?
