So we have 3 options: - I am not analyzing correctly cmake failure to compile and my finding can't be reproduce (I am wrong in some way). - GCC configuration (as provided by LFS) make no identical binaries, it depend on its compilation context. - Problem stand in cmake itself, but this is not detected by compiler in chapter-06 context.

Problem is proved (100%) to be related to contents of /usr/include/c++/8.1.0 (and only to this contents) I have made a diff, gcc-blfs come with 23 "extra" files as extracted by diff. Here they are: > usr/include/c++/8.1.0/bits/gthr-single.h > usr/include/c++/8.1.0/bits/c++config.h > usr/include/c++/8.1.0/bits/c++locale.h > usr/include/c++/8.1.0/bits/stdtr1c++.h > usr/include/c++/8.1.0/bits/c++io.h > usr/include/c++/8.1.0/bits/cxxabi_tweaks.h > usr/include/c++/8.1.0/bits/basic_file.h > usr/include/c++/8.1.0/bits/gthr.h
[...] Tracking extra file generation origin proved "I am wrong in some way". Yuppie!!Indeed I was recompiling gcc according LFS directive, but I have overlook the fact in the same shell script I was doing a
../libstdc++-v3/configure
and a
make (libstdc++-v3) install.
So it seems, doing so, I have compromised gcc code itself.
This is a misunderstanding of mine, believing
gcc and libstdc++v3 to be 2 different package
even if there are coming from the same
source tree.
To indulge myself and to find and excuse, this same mistake was in
my 8.1 and 8.2 and never show up....
Let me double-check finding and understanding, may
be I can come up with some suggestions for the
LFS book.
Many Thanks for all your advice.
