I think I've found the problem. It's in the -march setting, which of course has to be specific in the chroot, not "native." I had it set to "silvermont," but now I can't see why I did that. The target CPU is a celeron N3150, which according to an Intel site is "Products formerly Braswell" [1]. None of the Gentoo or GCC optimisation sites I could find even mention braswell, silvermont or model 76. So I changed make.conf to braswell, and now I get "error: bad value (braswell) for -march= switch" from the compiler during any emerge. Now, does that mean I can't switch from silvermont to braswell, or does it also imply that, if I start installing again from scratch, I won't be able to switch from whatever's in the stage-3 tarball to braswell either? Perhaps I should just try it and see. 1. https://ark.intel.com/products/codename/66094/Braswell -- Regards, Peter.
