(Android) Nodev0.8.1 Crash in the ExternalTwoByteString::GetChars()

[harlentan]

Hi all,
I try to port the NodeJs-v0.8.1 to Android. And I compile it successfully on Android.
But when i try run node on Android, it crashs in the V8 function ExternalTwoByteString::GetChars().

Define "crash". Segfault? Can you give us a gdb backtrace?

The backtrace:

I have use tools to convert to the function:

Now I have get over the V8 segfault. And now i run node, i catch up with the errors:

node.js:220
config = config.split('\n').slice(1).join('\n').replace(/'/g, '"');
^
TypeError: Cannot call method 'split' of undefined

Android is not a supported platform and we're already stretched thin enough that I don't want to waste time on this. But try talking to @paddybyers (paddybyers in #libuv on freenode.org), he has done a lot of work on getting node ported to android.

I got same build error for building v8 (not nodejs). Could you please let me know how to fix this?

[Mithgol]

You probably should just go and talk with @paddybyers as well.
