how to locate 'imqi.hpp' from node-gyp

Question

I am trying to use "nan" module to call MQ_CONNECT() from node.js

See

Node.js and C/C++ integration: how to properly implement callbacks? and https://github.com/nodejs/nan

When I use "node-gyp" it says it can not find "imqi.hpp", the MQ header

As far as I can see, the path to MQ includes has to be provided in "binding.gyp", and I have tried this without success:

{
    "targets": [
            {
                    "target_name": "mqconn",
                    "sources": [
                            "initall.cc",
                            "mqconn.cc"
                    ],
                    "include_dirs": [
                            "<!(node -e \"require('nan')\")",
                            "c:\MQ\tools\cplus\include"
                    ]
            }
    ]
}

Does anyboby have a clue on how to fix this ? Sebastian.

PD.- of course, the file is where the path indicates:

c:\>dir c:\MQ\tools\cplus\include\imqi.hpp
Volume in drive C is OS
Volume Serial Number is 12AA-0601

Directory of c:\MQ\tools\cplus\include

27/06/2013  02:00             1.538 imqi.hpp

Answer 1

Because binding.gyp is in JSON, the String "c:\MQ\tools\cplus\include"is a standard JavaScript String, and therefore the \ needs to be escaped to \\.

So you should replace "c:\MQ\tools\cplus\include" into "c:\\MQ\\tools\\cplus\\include".

I hope that fixes the problem...
