building project

[Aaron Bartell]

I am trying to build this project and am curious about the instructions in the README.md.

Here is a mv command that is being done from what I ~assume~ is the root of the project.

mv src $Node_Install_Path/lib/node_modules/npm/bin/node-gyp-bin

The ./src folder contains .h and .cc files. Here is what I see when I display the contents of the destination directory:

ls /QOpenSys/QIBM/ProdData/OPS/Node6/lib/node_modules/npm/bin/node-gyp-bin
node-gyp      node-gyp.cmd

Are those instructions correct? I could just try it, but it is requiring me to "hose" my base install of Node.js (which I try not to touch).

Hello Aaron, The other way to compile the addon is --

cd nodejs-idb-connector
npm init
npm i node-gyp
node node_modules/node-gyp/bin/node-gyp.js configure
node node_modules/node-gyp/bin/node-gyp.js build

Then you will get the build/Release/db2ia.node

This method will not touch anything of the base Node.js install. Actually Node.js contains the node-gyp tool as part of the npm tool, so I personally use that built-in one for build.

The project has supported npm.js now. We can simply install the project by

npm -g i idb-connector

If your node program reports "Error: Cannot find module 'idb-connector'", you can set the NODE_PATH --

export NODE_PATH=/QOpenSys/pkgs/lib/node_modules

And you can build the local project as well --

cd nodejs-idb-connector
npm -g i

@aaronbartell , shall we update the Wiki for the info?

Hi Xu Meng

I think that I have tried all of the above but I receive this message when I try to run my node program:

Error: Cannot find module '/xxx/js/node_modules/idb-connector/lib/binding/Release/node-v64-ibmi-ppc64/db2ia.node' Do you have any idea on how I can solve this problem?

I’m running on an IBM i 7.3 using qsh:

node -v v10.15.0 $
npm -v
6.4.1
$

Best regards Bent Ronne

Hello Bent Ronne,

Would you collect the full error message when run npm i idb-connector？

Hello Xu Meng

I have succeeded it to work for now by copying the missing directory from another “IBM i” partition. For the time being I have to focus on the project where I use IDB so I’m afraid to mess-up the installation right now. However, I found an installation log from one of the installations run of IDB and I hope this is good enough. Otherwise, please let me know and I will se what I can do.

I can see from the log that the installation program installs .../node-v48-ibmi-pcc/... rather than .../node-v64-ibmi-ppc64/... so maybe there is something here to go for.

npm install idb-connector
