Build failure with Node v6.12.1 on CentOS 7

[michaelfig]

First, thanks for node-addon-api: it allowed me to port old code to v8.9.1.

I'm trying to backport my module to v6.12.1, and I'm getting compile errors after following the steps in the Setup guide (and having it work perfectly under Node v8.9.1).

They all seem related to async_context not existing in v6.

Your help is appreciated,
Michael.

BTW, I used node-addon-api@1.0.0 for both compiles.

Hi @michaelfig,
If I understood you had problem with version 1.1.0 of node-addon-api while with 1.0.0 all worked well for you.
About that I'm curios so if your addon is a public addon please post the link at your code. I want try to take a look.

I can see that we define some of the functions reported as missing in https://github.com/nodejs/node-addon-api/blob/master/src/node_internals.h.

For example:

#if NODE_MAJOR_VERSION < 8 || NODE_MAJOR_VERSION == 8 && NODE_MINOR_VERSION < 6
typedef int async_id;

typedef struct async_context {
  node::async_id async_id;
  node::async_id trigger_async_id;
} async_context;

NODE_EXTERN async_context EmitAsyncInit(v8::Isolate* isolate,
                                        v8::Local<v8::Object> resource,
                                        v8::Local<v8::String> name,
                                        async_id trigger_async_id = -1);

NODE_EXTERN void EmitAsyncDestroy(v8::Isolate* isolate,
                                  async_context asyncContext);

v8::MaybeLocal<v8::Value> MakeCallback(v8::Isolate* isolate,
                                       v8::Local<v8::Object> recv,
                                       v8::Local<v8::Function> callback,
                                       int argc,
                                       v8::Local<v8::Value>* argv,
                                       async_context asyncContext);

#if NODE_MAJOR_VERSION < 8
class AsyncResource {
  public:
    AsyncResource(v8::Isolate* isolate,
                  v8::Local<v8::Object> object,
                  const char *name);
};
#endif // node version below 8

#endif // node version below 8.6

My guess is that possibly the issue is related to paths, with somehow the files from the node runtime being used instead of those provided as part of node-addon-api.

Can you provide some more info on anything special about your build setup ?

@gabrielschulhof adding you as an FYI as you did much of the work to support the older release and I wonder if you have run into some combination in the past that shows these symptoms.

Ah, thanks!

The installation and usage guide says to reference "1.0.0" in the package.json, but when I changed it to "^1.0.0" and npm update node-addon-api, I got 1.1.0 which adds the necessary support to v6.

Node-gyp has problems with v0.10 due to c++ flags, but at least 6.x works!

[NickNaso]

@mhdawson We need to change the reference in the installation and usage documentation.
@michaelfig Maybe I'm not really sure but I could works even if with Node.js 4.x

[michaelfig]

I've tested it successfully for node v4.8.7 as well.

Thanks.

Sounds like we can close this. If not please let me know and I'll re-open.
