node-gyb build error on hello world

I was trying to compile the node hello world addon and when I call node-gyp configure build it generates several errors.

../binding.cc:6:19: error: unknown type name 'FunctionCallbackInfo'
    void Method(const FunctionCallbackInfo<Value>& args) {
                      ^
../binding.cc:6:39: error: expected ')'
    void Method(const FunctionCallbackInfo<Value>& args) {
                                          ^
../binding.cc:6:12: note: to match this '('
    void Method(const FunctionCallbackInfo<Value>& args) {

What can be the problem?

Solution

  • The problem is that the example assumes you're running Node 0.12, but you're running Node 0.10 (0.10.36 by the looks of it). There have been big (backward-incompatible) changes in the way addons are structured in Node 0.12.

    Here's the 0.10-compatible version: https://github.com/joyent/node/blob/aa35564ca1c9f3854bc5f7983f2f00cb51f67ffe/test/addons/hello-world/binding.cc

    An awesome package that will take care of a lot of the differences between Node versions is nan.
