From a09520cdd91a87ada081b065c42256bec2be6946 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 12 Apr 2022 12:30:08 -0400 Subject: gdbsupport: use result_of_t instead of result_of in parallel-for.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building with -std=c++11, I get: In file included from /home/smarchi/src/binutils-gdb/gdb/unittests/parallel-for-selftests.c:22: /home/smarchi/src/binutils-gdb/gdb/../gdbsupport/parallel-for.h:134:10: error: ‘result_of_t’ is not a member of ‘std’; did you mean ‘result_of’? 134 | std::result_of_t | ^~~~~~~~~~~ | result_of This is because result_of_t has been introduced in C++14. Use the equivalent result_of<...>::type instead. result_of and result_of_t have been removed in C++20 though, so I think we'll need some patches eventually to make the code use invoke_result instead, depending on the C++ version.
