Build error with node.js on Windows 10

[RikVerbrugge]

Today I tried to build the node.js samples on Windows 10. But I receive this error when I run: build.cmd --enable-nodejs-binding

CMake Error at bindings/nodejs/CMakeLists.txt:12 (message): Environment variables NODE_INCLUDE and NODE_LIB are not defined. Please define NODE_INCLUDE to point to the location where the Node JS include files reside and NODE_LIB to point to the location where the Node JS library files reside. If you haven't built Node JS yet, then please run tools/build_nodejs.sh or tools/build_nodejs.cmd as appropriate.

I have installed node JS (and it is in path) and tried several time to rebuild with tools/build_nodejs.cmd

Any ideas?

Yes, add the variables NODE_INCLUDE and NODE_LIB to you environment and restart the command windows and try again.

After you build nodejs it will tell which value to put on these variables.

Let us know,

The gateway build scripts need to know where the Node.js headers and lib files are located. It relies on 2 environment variables for these 2 paths:

• NODE_INCLUDE should have the path to the folder containing the include files and
• NODE_LIB should have the path to the folder containing the lib files.

As @aribeironovaes said, when you run tools/build_nodejs.cmd or tools/build_nodejs.sh the script lets you know what values to set for these variables.

If you have cloned the repo at this location for instance - c:\code\azure-iot-gateway-sdk then the 2 paths are likely to have the following values:

set NODE_INCLUDE=c:\code\azure-iot-gateway-sdk\build_nodejs\dist\inc
set NODE_LIB=c:\code\azure-iot-gateway-sdk\build_nodejs\dist\lib

Thanks. Now I get several errors after setting the NODE (with the correct paths): (I did rebuild anything and then run the build command with enable nodjs binding

and things like this:

These errors mean that the environment variables were not defined when you ran build.cmd. uv.h should be available in %NODE_INCLUDE%. If the compiler is not able to find it then the variables were not defined or they had the wrong path.
