Try run from the tip of mozilla-inbound *without any changes made by me*: https://treeherder.mozilla.org/#/jobs?repo=try&revision=ad88e77dcf53 04:33:07 INFO - REFTEST INFO | runreftest.py | Running tests: start. 04:33:07 INFO - dyld: Symbol not found: _strndup 04:33:07 INFO - Referenced from: /builds/slave/talos-slave/test/build/application/NightlyDebug.app/Contents/MacOS/libmozglue.dylib 04:33:07 INFO - Expected in: flat namespace 04:33:07 INFO - in /builds/slave/talos-slave/test/build/application/NightlyDebug.app/Contents/MacOS/libmozglue.dylib 04:33:09 WARNING - TEST-UNEXPECTED-FAIL | reftest | application terminated with exit code -5

This failure started yesterday or the day before.

It seems bug 1141679 is related to it somehow.

Actually, it's bug 1141745, though I fear that might be misdiagnosing the cause.

Thanks. So would touching CLOBBER in my Try pushes work as a temporary workaround?

Would certainly be an interesting experiment, though I don't see any sign that the clobber with the clobberer that they did yesterday did any good, nor do I see any obvious reason why the couple of pushes that got useable builds in the last couple of days actually did get usable builds.

Try this: - add the following to build/mozconfig.common.override: mk_add_options "export SCCACHE_RECACHE=1" - push a try build for mac with that mozconfig change. - if you get green tests, try again without the mozconfig change.

OK, here's the first run: https://treeherder.mozilla.org/#/jobs?repo=try&revision=0fc1c29fe8d4

It failed with the same error.

Bug 1141745 was mentioned as a possible dupe of this and has an assignee.

(In reply to Mats Palmgren (:mats) from comment #8) > It failed with the same error. :( did you try touching CLOBBER?

CLOBBER doesn't fix it, and I'm getting close to say it's caused by the combination of bug 868814 and the use of sccache on try, and specifically, the fact that sccache is compiling preprocessed files.

So, it's probably not exactly that. The problem is indeed caused by the combination of bug 868814 and sccache. But when the sccache server starts, MACOSX_DEPLOYMENT_TARGET is not set, and that doesn't make strndup references weak (which happens when MACOSX_DEPLOYMENT_TARGET is set to 10.6).

On try, where we use sccache, a sccache server is started the first time configure runs the compiler for its checks, and that sccache server is what does compilations on cache misses. But compiling with MACOSX_DEPLOYMENT_TARGET in the environment doesn't have the same effect as without, depending on its value. So MACOSX_DEPLOYMENT_TARGET needs to be set before any compiler invocation.

Try OSX builds works now for me. Thanks!

Has this been really fixed? I can still see failures on try. https://treeherder.mozilla.org/#/jobs?repo=try&revision=bd3d1244e4ef https://treeherder.mozilla.org/#/jobs?repo=try&revision=266ead189253

@hiro, I suspect you need to update your local tree.

Thanks! I totally forgot to update the tree before pushing!
