<br>
I have been trying to get this buildbot green for a while...<br>
<br>
<a href="http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/" target="_blank">http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/</a><br>
<br>
but for some reason, those four tests fail:<br>
<br>
FAIL: Clang::fmodules-validate-once-per-build-session.c<br>
FAIL: Clang::prune.m<br>
FAIL: Clang::validate-system-headers.m<br>
FAIL: LLVM::archive-update.test<br>
<br>
I have no idea why, since the same build on other ARM boards work perfectly.<br>
<br>
I have completely removed the buildbot directory, re-created,<br>
restarted, and still the same four errors occur. I have updated the<br>
system, removed spurious packages, moved the version of all relevant<br>
tools (compiler, cmake, ninja, etc) to the other bots, for instance:<br>
<br>
<a href="http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-a15" target="_blank">http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-a15</a><br>
<br>
which is green ever since. I also run NEON and non-NEON ARMv7 tests on<br>
my test box and all tests pass.<br>
<br>
It seems that the problem is with versions of the modules that get<br>
included, for example:<br>
<br>
<a href="http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/4811/steps/ninja%20check%201/logs/FAIL%3A%20LLVM%3A%3Aarchive-update.test" target="_blank">http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/4811/steps/ninja%20check%201/logs/FAIL%3A%20LLVM%3A%3Aarchive-update.test</a><br>
<br>
archive-update.test:34:8: error: expected string not found in input<br>
NEWER: newer<br>
^<br>
<stdin>:1:1: note: scanning from here<br>
older<br>
^<br>
<br>
Does anyone have any idea on how to fix this issue? I don't think it's<br>
in Clang itself, but I can't think of anything else to do in the<br>
machine... My last resort will be to kill that machine and re-install<br>
from scratch, but that would be to admit failure. :)<br>
<br>
cheers,<br>

PS: Those problems occurred after a power cut, which left all my bots<br>
in a terrible state. All others recuperated well, not this...<br>
