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
