AFAICT, no one among the editors have the first line. Only baseline is "needed", not v2 nor v3, although we have more recent CPUs. I cannot tell how this "needed" line is determined, but I see in config.log you have -march=native. Maybe you could try without any CFLAGS, and check that you do not have the v2 and v3 in "needed". BTW, you say you have the warning, but it does not stop the build does it? Everyone seems to have the warning in a couple of tests in binutils chapter 8 (ld tests). > > with as contrast to the ch5 output: > Properties: x86 ISA needed: x86-64-baseline > x86 ISA used: x86-64-baseline, x86-64-v2, x86-64-v3, x86-64-v4 > > However, still getting the next message during testing. > '/sources-base/glibc-2.33/glibc-build/libc.so.6: CPU ISA level is > lower > than required' > > After the tests and install, I get the ISA message with everything I > do. > Maybe the x86_64-baseline is not the original baseline anymore, > thereby > making my processor and many others obsolete according to the glibc > devs? > Maybe adding --with-CPU to the configuration might help? Well, as said above, try without flags. Then you could add them one by one...
