static_pointer_cast not declared in this scope

[Tim H]

help?!?

#include <boost/shared_ptr.hpp>
class pp_dirent {};
class pp_scope: public pp_dirent {};

int main() {
boost::shared_ptr<pp_dirent> p1(new pp_scope());
boost::shared_ptr<pp_scope> p2 =
static_pointer_cast<pp_scope>(p1);
return 0;
}


g++ test.cpp -o test
test.cpp: In function int main():
test.cpp:8: error: static_pointer_cast was not declared in this scope
test.cpp:8: error: expected primary-expression before > token


What?

You have an error in function 'main'.

test.cpp:8: error: static_pointer_cast was not declared in this scope

It was that 'static_pointer' was not used but haven't been declared.
Perhaps you meant something like 'boost::static_pointer_cast'.

test.cpp:8: error: expected primary-expression before > token

And at the point of detecting that, the compiler had parsed your code as
far as the latest '>' token on line 8, where it expected a primary
expression, not some undeclared name.

What?

What what?

Just read the compiler's diagnostic messages.

Corrected typos:
