Cross Compiling Node.js for ARM on Ubuntu

Node.js is available for many different operating systems and architectures. We can run it on our Macbooks locally, on full server grade systems, and on IoT devices with ease. The Node Foundation publishes binary tarballs for a broad spectrum of target platforms. Over at NodeSource we packagethose builds up for Linux to make them easy to install. However, building Node.js for architectures other…

My Environment - Buildroot on Ubuntu for attitude_adjustment

Assuming buildroot is in your home dir

1.In buildroot create the packages folder 

mkdir ~/openwrt/attitude_adjustment/feeds/packages/utils/zeromq

2.Create the Makefile for the package 

cd ~/openwrt/attitude_adjustment/feeds/packages/utils/zeromq 

vim Makefile

3.Get contents of Makefile from the git link - https://github.com/vperron/openwrt-zmq-packages/blob/master/zeromq/Makefile

Make sure u get the raw version with the TABS (else there are build errors) from here https://raw.githubusercontent.com/vperron/openwrt-zmq-packages/master/zeromq/Makefile

4.Update and Install in the feeds in the buildroot

cd ~/openwrt/attitude_adjustment/scripts/

./feeds update -i

./feeds install zeromq

5.Run make menuconfig

cd ~/openwrt/attitude_adjustment

make menuconfig

From Libraries select zeromq, add M next to it and select Exit twice, choose to save the config file when prompted

6.Compile

make package/zeromq/compile

7.Error compiling

I got an error - so run with verbose option to see the error

make V=s package/zeromq/compile

If there are github key errors - 

Create a public key following this https://help.github.com/articles/generating-ssh-keys/

Add your key to your github account https://help.github.com/articles/keeping-your-ssh-keys-and-application-access-tokens-safe/#reviewing-your-ssh-keys

Verify you can ssh with

ssh -vT [email protected]

If all is ok again execute

make package/zeromq/compile

8.If there are no error messages you will find a zeromq_something_ar71xx.ipk file in openwrt/attitude_adjustment/bin/ar71xx/packages

9.FTP/WGet that file onto the target openwrt

10.Install dependencies for zeromq

opkg update

opkg install libstdcpp

opkg install librt

9.Install ipk on target
