Maybe I'm totally wrong, but if GCC10.1 is released May 2020, and even 10.4 is released 2022, then shouldn't we expect the kernel releases around 2020 can be compiled for all GCC 10.x releases? Thus the initial release date should be a good enough hint for most cases. If go this method, for v4.14 I guess I should go gcc 7.x, as gcc 7.1 is released May 2017, even the latest 7.5 is released 2019. Or is my uneducated guess completely wrong? Thanks, Qu > > Willy
