From ebd83c14476470e7b06b2720d7cc61993c135fe3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9mie=20Galarneau?= Date: Tue, 30 Jul 2024 19:21:07 +0000 Subject: [PATCH] Fix: missing typename in URCU_FORCE_CAST MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When using rcu_dereference() in the method of a templated class on a pointer whose type is determined by the template arguments, the following error occurs (using g++ 13.2.0): ../../src/common/urcu.hpp:387:39: error: need 'typename' before 'std::remove_cv<__typeof__ (((lttng::urcu::rcu_list_iteration_adapter::iterator*)this)->_node_contents.next)>::type' because 'std::remove_cv<__typeof__ (((lttng::urcu::rcu_list_iteration_adapter::iterator*)this)->_node_contents.next)>' is a dependent scope `typename` is necessary here since the result of the template argument provided to std::remove_cv can be a dependant type and we are required to inform the compiler of this dependency.
