--- Comment #11 from Nicolas Arnaud-Cormos <nicolas.arnaudcor...@gmail.com> --- I don't see how it will help me. The problem is not necessary when building KSyntaxHighlighting (even if in my case I'm also building it with C++20), but rather when using it in another library/application, with the include paths containing the direct path to the Format header. Which is the case for me when using fetchcontent from CMake. The patch from Ahmad should help, as now you need to #include <KSyntaxHighlighting/Format> to access it, so #include <format> should point to the right one in the std. -- You are receiving this mail because: You are watching all bug changes.
