My C++ module works on node 6.2.2 but it crashes on nwjs 0.15.4 for Linux

Hi,

Thanks for great work with nwjs.

I am trying to use 0.15.4 for my project. My module written in C++ and wrapped using node-ffi works well with nodejs 6.2.2 but when I tried to use it with nwjs 0.15.4, it crashed (I only tested on Linux)

In the console, it says

nw: ../../nan/nan.h:679: Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char*, size_t, node::Buffer::FreeCallback, void*): Assertion `length <= imp::kMaxLength && "too large buffer"' failed.

Thanks!
Cuong.

It needs re-compile with the header files provided by NW. Previously we supported using node binary modules directly but now it's broken due to v8 ABI change.

@rogerwang I read the issue about the v8 change and i am interested, is it possible to support node binary modules in the future again?

[rogerwang]

@kailniris yes, as long as the ABI of different v8 versions in Node and Chromium are compatible. So let's wait for the next v8 upgrade in Node and see.
