Hi, recently ardour5 failed to build in rawhide, I think because glibmm now requires c++14. I patched the spec at the beginning this way and it works on my pc: # glibmm needs --std=c++11 for F-23..F-27 and --std=c++14 for F-28 and later # --std=c++14 is the default for F-28 %if !0%{?fedora}%{?rhel} || ( 0%{?fedora} >= 23 && 0%{?fedora} < 28 ) || 0%{?rhel} >= 8 %bcond_without cxx11 %else %bcond_with cxx11 %endif But I think we should remove all c++ explicit standard selection and let the compiler use its default, which should work for every fedora version (I hope). What do you think about it? Nils, please let me know your opinion when you have time.
