I'm getting unexpected test failures in glibc (8.3-systemd, chapter 6.9). make check exits with: ... Summary of test results: 3 FAIL 5823 PASS 31 UNSUPPORTED 17 XFAIL 2 XPASS make[1]: *** [Makefile:347: tests] Error 1 make[1]: Leaving directory '/usr/src/glibc-2.28' make: *** [Makefile:9: check] Error 2 The 3 FAILs are: FAIL: inet/tst-idna_name_classify FAIL: libio/tst-readline FAIL: misc/tst-ttyname The 2 XPASSes are: XPASS: elf/tst-protected1a XPASS: elf/tst-protected1b inet/tst-idna_name_classify and misc/tst-ttyname are mentioned in the book, but not inet/tst-idna_name_classify. Is it safe to continue at this point? With one extra failure, yes. We don't usually note or care about XPASS, only what actually fails. Having one or two more here is no big deal. But there is no hard and fast rule - having 20 more is bad, having 6 more - maybe, maybe not. FWIW, I only got 1 on the machine I looked at, because one other was 'unsupported' so to an extent the results vary, probably with micro-architecture and kernel configuration. Thanks. I will continue with my build as usual. I've backed up $LFS/tools anyway in chapter 5.36, so if everything goes wrong I could just go back to this point. Also, what is the best strategy to find out more about a specific error? Google searches mainly lead to archives of test results, but not to an explanation. Thanks a lot, Hans Necromancy ? Sometimes an explanation will be hinted at after reading several results across the first few pages. But other times, nothing - and to an extent it will depend on what google knows about your search history, but more, these days, to what other people are commonly searching for. ĸen -- Is it about a bicycle ? -- So are these tests documented in detail somewhere? The glibc website doesn't give explanation of the individual test cases as far as I can see. Thanks a lot, Hans
