v6.5.0 fails to build using clang-3.4. #8323

Fishrock123 · 2016-08-29T15:40:54Z

Version: v6.5.0
Platform: Debian, Ubuntu ... using clang-3.4
Subsystem: build

Our package builds for Debian Wheezy, Ubuntu Precise, and perhaps others, are failing on v6.5.0 using clang-3.4.

This seems to be a regression possibly introduced by V8 5.1.

Can you post or link to the build log?

chrislea · 2016-08-29T15:53:21Z

What I've seen building 6.5.0 this morning is that the builds fail during the V8 compilation on both Ubuntu Precise and Debian Wheezy. Both were trying to use clang-3.4 because the default compilers that ship with those distros have been too old to compile a modern V8 for some time now.

The builds failed in the same way for Wheezy and Precise, on both 32bit and 64bit architectures. The error message in all cases from clang looked like this:

clang: note: diagnostic msg: 
********************

PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT:

I have attached those mark-compact-* files here, gzipped.

Newer versions of Debian and Ubuntu (which do have gcc new enough to work out of the box) are building just fine.

chrislea · 2016-08-29T15:56:06Z

Working on getting a full build log @bnoordhuis, please stay tuned.

chrislea · 2016-08-29T16:22:17Z

Full build log attached @bnoordhuis. This was attempting to build on Ubuntu Precise, amd64, with clang 3.4. However, the errors look the same in all the contexts where I saw the builds die. Please let me know if there's any additional details I can provide.

bnoordhuis · 2016-08-29T16:33:26Z

@chrislea Thanks. It's hitting an ICE, an internal compiler error. You're using clang 3.4.1 now. Is testing with 3.4.2 an option for you?

If that doesn't fix the issue, we have three options:

Revert the V8 upgrade. (I don't think this is really an option but I put it in for completeness.)
Tweak mark-compact.cc until it avoids the ICE.
Update the minimally supported clang version to 3.5 or 3.6.

Fishrock123 · 2016-08-29T16:41:29Z

I think 3. is out of the question - that's effectively a breaking change.

Revert the V8 upgrade.

Less breaking than 3. at this point.

chrislea · 2016-08-29T16:43:45Z

@bnoordhuis going to a newer version of clang is not immediately possible, as in, I can't do it in the next 30min. But I can look into it and see how much work will be involved.

ofrobots · 2016-08-29T16:44:03Z

Why is 3 a breaking change?

Fishrock123 · 2016-08-29T16:57:32Z

We're now failing to compile on mainstream linux distros we previously compiled on...?

ofrobots · 2016-08-29T17:02:11Z

Yes, but that is not a breaking change for users. People who build packages are impacted, yes, but if we can build a package successfully using either 3.5 that is compatible on that distro, it is not a breaking change.

Commenting out the lambda line makes the ICE go away. I think we should be able work around this issue by converting the lambda to function. I would still be interested in reports on whether clang 3.4.2 has already fixed this problem.

I just tried building with clang-3.4.2 without the above workaround, and I no longer see the internal compiler error. I think switching to building w/ 3.4.2 if at all possible is going to be a better solution.

jbergstroem · 2016-08-29T18:40:59Z

@ofrobots doesn't look like it: http://packages.ubuntu.com/precise/clang-3.4

bnoordhuis · 2016-08-30T02:57:31Z

Is the argument that we can't bump the requirement to 3.4.2 because precise only ships 3.4.1?

I don't have a problem with that. It only affects the intersection of users that build from source on precise. They can still use the binaries from https://nodejs.org/.

jbergstroem · 2016-08-30T03:34:03Z

@bnoordhuis I wouldn't call it that, just stating that it doesn't seem to be available and I have no real insight into precise packaging. Can only assume its.. careful.

chrislea · 2016-08-30T16:39:02Z

Actually, there are other options for Precise. Ubuntu Wheezy is the real problem. I tried all day yesterday to get a sane compiler new enough made for Wheezy that would work and failed in a variety of different ways. I don't think we can do it without a) a lot more work or b) forcing people running Wheezy to upgrade their libstdc++, which I don't want to do. So I think we will have to drop support for Wheezy.

So I think we will have to drop support for Wheezy.

That won't be so great to do for v6.x. Let me polish up and PR the diff from #8323 (comment).

Independently, a head's up that Node v7.x will require a more modern compiler toolchain as V8 5.4 has started to depend upon C++11 compiler and runtime features.

#8343

chrislea · 2016-08-30T17:56:22Z

Okay. That may be wise @ofrobots since as far as I can tell, there's a similar situation for Ubuntu Precise (which I know people are actually really running out in the wild). I don't think we can ship this "as is" unless we update libstdc++6 on the target host, which we'd rather avoid obviously.

Do you have more details about this? I think this would be worth opening a separate issue, unless it's been done already.

ofrobots · 2016-08-30T19:20:27Z

The WIP PR to bring in V8 5.4 is here: #8317 and there some related discussion on #7844 about the next version of ICU also requiring C++11.
