The V8 bundled with node currently requires an ARM CPU supporting VFP3 for
hard-float support, causing problems when trying to compile for ARMv6
devices like the Raspberry Pi.
There is a patch that was committed upstream
at http://codereview.chromium.org/10818026/ but does not apply cleanly to
the bundled V8 source, and attempting to replace it with version V8
version 3.12.17 which does include the fixes, produces a `error:
‘MAP_TRANSITION’ was not declared in this scope`. How do you normally apply
an upstream patch like this - would it be better to try and get 3.12.17 to
compile or to try and backport all the necessary changes to the bundled
source somehow? Or is there a better way to go about trying to get it
working on ARMv6 with hard float I haven't thought of yet?
Thanks.

Whoops, I forgot to mention I had tried both a 0.8.6 release and the master
branch - they appear to be quite far apart in terms of v8 so that's another
complicating factor.

You probably botched the upgrade, e.g. by leaving old files around. I
usually upgrade V8 as follows:

  rm -rf deps/v8/ && (cd /path/to/v8 && git archive --format=tar
--prefix=deps/v8/ <commit>) | tar x

Where /path/to/v8 is a clone of https://github.com/v8/v8 and <commit>
is the commit or branch name (possibly just HEAD).

Thanks for the quick command.

I'm still getting the same errors as before though I think:

  g++ '-D_LARGEFILE_SOURCE' '-D_FILE_OFFSET_BITS=64'
'-DENABLE_DEBUGGER_SUPPORT' '-DV8_TARGET_ARCH_X64' -I../deps/v8/src

Error 1

Is this an error in V8, or just something has changed between the
version node supports and the later version of V8?
For reference, this is with node master and v8 3.12.19

Some V8 internals changed. Try this[1] or this[2].

[1] https://github.com/bnoordhuis/v8/commit/add4152
[2] https://github.com/bnoordhuis/v8/commit/343b98c

Append .patch to get the patch file.
