KDevelop: Error on using std::format in C++20

Help
1

When using std::format with a format argument of type std::string or char *, KDevelop complains about it even though it compiles just fine.

I’m wondering if I misconfigured something here.

KDevelop Version 6.3.250803 (25.08.3)

Hi, you either need to set C++20 explicitly in cmake (it passes -std=c++20 as compiler arguments and kdevelop should pick it up), or in project configuration → Language support → C/C++ parser. Next version of kdevelop (26.04) will default to C++20.
