Hi Frans,
Could you send the result of
$LFS_TGT-readelf -a $LFS/lib/libc.so.6 | grep ISA
The line '$LFS_TGT-readelf -a $LFS/lib/libc.so.6 | grep ISA'
returns
nothing.
You need to use readelf from binutils 2.36. If you have back up to
2.35.1, it returns nothing.

Okay, I have recompiled ch5, ch6 and ch7 as well as up to and
including
glibc-2.33 and using binutils-2.36.
Attached is the result of that latest config.log (ch8). Other results
are found in previous messages.
Also, the output of readelf in ch8:
Properties: x86 ISA needed: x86-64-baseline, x86-64-v2, x86-64-v3
x86 ISA used: x86-64-baseline, x86-64-v2, x86-64-v3, x86-64-v4
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...
Pierre
I will try that as a last resort. Have not read your previous suggestion
completely ;)
