similar to: failing bootstrap: C++11 or greater is required but the compiler does not support c++11

I can't reproduce right away. I wonder if the check for the -std=c++11 flag is failing due to the earlier error about failing to find libatomic.

FTR, I've disabled libcxx checkout on that particular bot <http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer> to make it green. The problem remains, of course. :( On Sun, Dec 11, 2016 at 7:23 AM, James Knight <jyknight at google.com> wrote: > On Dec 11, 2016, at 3:33 AM, Eric Fiselier via llvm-dev < > llvm-dev at lists.llvm.org> wrote: > > So it

started with http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer/builds/1380 (Fri Dec 9 18:42:04 2016) The previous one (Fri Dec 9 17:41:56 2016) was fine. There was just one revision between these runs (mine), but reverting it does not help. Maybe an update in Ubuntu 14.04 broke this?

(kcc, george: sorry for the re-send, the first was from a non-list email address) My configuration for building the fuzzers in the LLVM tree doesn't seem to work any more (possibly as of moving libFuzzer to compiler-rt, but there have been a few other changes in the last week or so that may be related). I'm building with a fresh top-of-tree clang and setting -DLLVM_USE_SANITIZER=Address

So it seems that libatomic went missing between build #1379 and #1380, so I don't think this is related to the -std=c++11 failure. Instead it seems likely that the compile test for -std=c++11 is failing due to mis-configuring -latomic. Can you confirm the bot has libatomic installed? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, A few tests seem broken for a long time, some for more than a month. Would it possible for respective owners to take a look please?

Hi llvm-dev, I'm trying to reproduce an msan failure in one of the bots, but I can't seem to get the right incantation of building LLVM with msan. Here's what I've been doing: 1) Build the toolchain in one build directory, including `compiler-rt`. 2) Build the toolchain again with the just built toolchain in step 1, but this time with `-DLLVM_USE_SANITIZER=MemoryWithOrigins`. I

Another option is just to run corresponding script from *https://llvm.org/svn/llvm-project/zorg/trunk/zorg/buildbot/builders/sanitizers/ <https://llvm.org/svn/llvm-project/zorg/trunk/zorg/buildbot/builders/sanitizers/>* in empty directory.

Aside: would it be useful to execute a build of the libc++/libc++abi with msan normally during release, and change the driver to look for these msan-built C++ libs when "-fsanitize=memory"? That would drastically cut down on the complexity of using msan. On Fri, Aug 31, 2018 at 5:43 AM Dean Michael Berris via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Thanks Vitaly and

> If 3.9 shipped with these issues (assuming these are not false positive), it would be interesting to 1) know why the sanitizers didn’t catch it, and 2) add valgrind to the release qualification process (CC Hans). Yes, I'd be interested to see some corroboration. Note that the issue here is pretty specific: it only happens during optimized compile using Clang-3.9. This is all I did:
