Node crashes in V8 on Raspberry Pi

[deanm]

Problem is that v8 generates an mls instructions (arm ARMv6T2).

This was fixed upstream:

commit 70d11c79c7833b9ab1ee185625fcf707b9480a40
Author: machenbach@chromium.org <machenbach@chromium.org@ce2b1a6d-e550-0410-aec6
Date: Mon Jun 16 00:04:47 2014 +0000

Version 3.27.29 (based on bleeding_edge revision r21835)

Emulate MLS on pre-ARMv6T2. Cleaned up thumbee vs. thumb2 confusion.

X87: Fixed flooring division by a power of 2, once again.. (issue 3259).

Fixed undefined behavior in RNG (Chromium issue 377790).

Performance and stability improvements on all platforms.

Segfaulting on Raspi after installing according to https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager#debian-and-ubuntu-based-linux-distributions, too.

Which version were you seeing that issue on? The latest 0.12 is on 3.28.23 committed 12 days ago and has the MLS emulation in there.

[deanm]

I don't really follow Node's branch policy, according to:

https://github.com/joyent/node/blob/master/CONTRIBUTING.md

New work is done on the master branch, but you're saying that v8 has been upgraded on another branch but not on master?

[andig]

I have only tested using packaged versions according to https://github.com/joyent/node/wiki/installing-node.js-via-package-manager#debian-and-ubuntu-based-linux-distributions. Latest I can seem to get that way is 0.10.32 which crashes.

Is the fix being backported to 0.10.* / master branch?
Is there any chance to test other than compiling (takes ages on raspi)?

[trevnorris]

@andig can you test on latest v0.11?

[andig]

Using https://deb.nodesource.com/setup:

Setting up nodejs (0.10.34-1nodesource1~wheezy1) ...
pi@prodpi ~ $ node
Segmentation fault

Using https://deb.nodesource.com/setup_dev:

Setting up nodejs (0.11.14-1nodesource1~wheezy1) ...
pi@prodpi ~ $ node
Illegal instruction

Not too helpful :(

@andig it's fixed in source, so you really need to take this up with nodesource, since you're getting node from them.

And it looks like they already have an open issue for it: nodesource/distributions#44

[andig]

Which source do I need to compile for 0.11? Which branch?

[bahamat]

This should have it: https://github.com/joyent/node/tree/v0.12

[andig]

Cloned git, checked out v0.12 branch. configure/make.

UPDATE This should be better suited to show the error:

  LINK(target) /home/pi/node/out/Release/mksnapshot: Finished
  LD_LIBRARY_PATH=/home/pi/node/out/Release/lib.host:/home/pi/node/out/Release/lib.target:$LD_LIBRARY_PATH; export LD_LIBRARY_PATH; cd ../deps/v8/tools/gyp; mkdir -p /home/pi/node/out/Release/obj.target/v8_snapshot/geni; "/home/pi/node/out/Release/mksnapshot" --log-snapshot-positions --logfile "/home/pi/node/out/Release/obj.target/v8_snapshot/geni/snapshot.log" "/home/pi/node/out/Release/obj.target/v8_snapshot/geni/snapshot.cc"
Illegal instruction

make[1]: Leaving directory '/home/pi/node/out'
Makefile:45: recipe for target 'node' failed
make: *** [node] Error 2
pi@prodpi ~/node $

Further looking into this shows that the mksnapshot tool fails with illegal instruction.

So long story short- still broken in 0.12, no changes to 0.11. How can it be that ever since 0.10.8 we don't have node on raspi?

PS.: whoever is stuck on RasPi/ Raspbian can download working node 0.10 packages at http://node-arm.herokuapp.com/

I had successfully built and run Node/V8 on the Raspberry Pi, there were a few changes necessary, this bug was only one of them. Without checking I don't remember all of the details, but it is likely some of the build settings are wrong, for example, I vaguely remember something like

https://github.com/joyent/node/blob/v0.12/configure#L495

I believe vfpv3 is ARMv7, while the rpi is ARMv6.

having this problem for so long is not serious at all
