| |
Hi there,
I apologize in advance if this question is inappropriate for this mailing list. I welcome any suggestions for a more appropriate forum.
I am running kernel 2.6.11.12 on an AMD Athlon 64, but the kernel is just the straightforward i486 compilation -- no optimizations, no 64-bit. The distribution is LFS 6.1, which apparently runs without any problem. The glibc version is 2.3.4, built with gcc 3.4.3.
When I build glibc 2.3.4, 2.3.5, or 2.3.6, using gcc 3.4.3 or 4.0.2, the "make check" test suite fails exactly one test, which I think may be due to the kernel. The "nptl/tst-clock2.c" test fails (in every configuration listed), and we have:
/sources/glibc-build# cat /sources/glibc-build/nptl/tst-clock2.out difference between thread 0 and 1 too small (0.053511687)
Here is a link to a person who has reported exactly the same problem, although he does not indicate if he is using an AMD64 processor: http://archives.linuxfromscratch.org/mail-archives/lfs-support/2005-August/028065.html
Does anyone have any insight into this problem? There is next to nothing on google about it (search on "tst-clock2"), which makes me think it's some rare combination of processor and kernel.
Again, I welcome any suggestions for a more appropriate forum. I wanted to ask here before trying the glibc mailing lists, because they seem pretty clear about not entertaining build error questions.
