As a matter of fact, there is no standard type for lambdas. ... not retain state within a scope, and function ... function is a lambda. The latest version of this topic can be found at Lambda Expression Syntax. Dealing with multiple captures. Global variables, static members can be used but they are not captured. If you have to use a lot of external variables inside the lambda, the capture list can become a bit long. As a special bonus: If there are no captured variables, then there is an additional conversion operator that can convert the lambda to a pointer to a nonmember function. Is this a bug in g++ 4.6, or is it really necessary to capture the 'this' parameter to be able to call a static member function? It is true that a lambda can be assigned to a std::function, but that is not its native type. ... C++ Lambda: Access static method in lambda leads to error 'this was not captured for this lambda function' ... in-lambda-leads-to-error-this-was-not-captured Try adding f to the capture list (change [] to read [&f]). [PATCH] [lambda] Extract lambda functions from semantics.c. Lambda One important thing to note is that a lambda is not a std::function. Why does lambda need 'this' since 'a' is a static member function. lambdas require capturing 'this' to call ... not captured for this lambda function Lambda Expressions in C++. CPP-10180 Compile error "'this' was not captured for this lambda function" not detected Duplicates: CPP-3191 Relates to: CPP-8797 Subtask of: CPP-3191 Reproduce: The latest version of this topic can be found at Lambda Expression Syntax. ... a lambda's function call operator is ... see "Higher-Order Lambda Expressions" in Examples of Lambda Expressions. The this pointer can only be captured by value, not by reference, and it is const qualified, if the method in which the lambda expression is used, is const qualified as well. For example, The anonymous function is not supported by ... Lambda functions are function objects of ... mkAdder returns an anonymous function, which has captured ... C++ Lambda: Access static method in lambda leads to ... not captured for this lambda function) ... in lambda capture list inside a member function; ... to the for_each function is a lambda. It means you want the lambda to capture the "this" pointer. If you have any opinions on this, please leave a comment! If a lambda expression (or an instantiation of a generic lambda's function call operator) ODR-uses this or any variable with automatic storage duration, it must be captured by the lambda expression. Caveat. I don't see why it should be, I even qualified the call with B::. What is a lambda (function)? Home C++ lambdas require capturing 'this' to call static member function? Capturing this pointer inside lambda function will automatically capture all the member variables for this object inside lambda. Lambdas didn't come to C++ as a specific-purpose feature (i.e., functional programming): the existing STL components, like the for_each algorithm, and its new ones like or , allow you to specify function arguments CPP-10180 Compile error "'this' was not captured for this lambda function" not detected Duplicates: CPP-3191 Relates to: CPP-8797 Subtask of: CPP-3191 Reproduce: Depending on how you work, using lambdas may make testing more difficult. Bug 51494 - Legal program rejection - capturing "this" when using static method inside lambda This is possible only in the case of no captured variables because captured variables would require an AnonymousClass$0 instance parameter, but there is Well talk about what that means soon. test.cpp: In lambda function: test.cpp:44:21: error: 'this' was not captured for this lambda function (Interestingly, g++ 4.5 compiles the code fine).
