[lfs-support] 8.2-systemd, chapter 6.20: making sense of the gcc test results

[Hans Malissa]

I'm in the process of building LFS 8.2-systemd on x86_64, and so far I've followed the instructions up to chapter 6.20 without problems. In chapter 6.20, when running the gcc test suite, I'm getting 6 FAILs in the libstdc++ tests:

FAIL: experimental/filesystem/iterators/directory_iterator.cc execution test
FAIL: experimental/filesystem/iterators/recursive_directory_iterator.cc execution test
FAIL: experimental/filesystem/operations/exists.cc execution test
FAIL: experimental/filesystem/operations/is_empty.cc execution test
FAIL: experimental/filesystem/operations/remove.cc execution test
FAIL: experimental/filesystem/operations/temp_directory_path.cc execution test

I've noticed that the very same FAILs are listed on http://www.linuxfromscratch.org/lfs/build-logs/8.2/i7-5820K/test-logs/086-gcc-7.3.0 but I couldn't figure out whether that means that this is a problem or not, and what needs to be done about it. Is it safe to proceed with the installation at this point?

If they are in the official check logs, that means that everyone has them, even the LFS developers. That's why the section on checking gcc has a link to those logs.

The book also mentions those failures in libstdc++. So you have nothing to worry about.
