Seattle-OpenWRT

Seattle is an open research and educational testbed that utilizes computational resources provided by end users on their existing devices. This project offers an OpenWRT package for Seattle.

How to create an OpenWRT package for Seattle

1. Get OpenWRT SDK

barrier_breaker: https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/
chaos_calmer: https://downloads.openwrt.org/chaos_calmer/15.05-rc2/ar71xx/generic/
Then you need to extract the tarball.

2. Download Seattle codes and Makefile

Assuming that your SDK parent(root) directory is as below OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2

cd OpenWrt-SDK-ar71xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1/package
git clone https://github.com/XuefengHuang/seattle-package.git
mv seattle-package seattle

3. Execute make

Now, go to your OpenWRT SDK directory and simply execute 'make', then all build start.

cd ..
make clean && make world

If you get errors like awk: include/scan.awk: line 21: function asort never defined, you need to install gawk.

4. Check package

When your build is sucessfully completed, You can find the build package (seattle_1.0-1_ar71xx.ipk) in below folder OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2/bin/ar71xx/packages(barrier_breaker) or OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2/bin/ar71xx/packages/base(chaos_calmer)

5. Copy your package to Router

Copy this ipk package (in this example seattle_1.0-1_ar71xx.ipk file) to router by any useful tool such as SCP.

6. Install your package

opkg install seattle_1.0-1_ar71xx.ipk

You also can use dest-name as the the root directory for package installation, removal, upgrading. dest-name should be a defined dest name from the configuration file. For instance, the only configuration file is /etc/opkg.conf. It could look like this:

src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages
dest root /
dest ram /tmp
dest test /root
lists_dir ext /var/opkg-lists
option overlay_root /overlay

Then you can run this command:

opkg install seattle_1.0-1_ar71xx.ipk -dest test

7. Uninstall your package

opkg remove seattle

Build an OpenWRT image include Seattle

These steps were tested using OpenWRT-"Barrier Breaker" (14.07): For building OpenWrt on Debian, you need to install these packages:

apt-get install git subversion g++ libncurses5-dev gawk zlib1g-dev build-essential gettext unzip file

Now build OpenWrt:

git clone git://git.openwrt.org/14.07/openwrt.git
cd openwrt

./scripts/feeds update -a
./scripts/feeds install -a

git clone https://github.com/XuefengHuang/seattle-package.git
mv seattle-package seattle
cp -rf seattle/ package/
rm -rf seattle/

make defconfig
make menuconfig

At this point select the appropiate "Target System" and "Target Profile" depending on what target chipset/router you want to build for. Also mark the Seattle package under "Network". You also need to mark the dependencies, such as python, libpthread...

Now compile/build everything:

make

The images and all *.ipk packages are now inside the bin/ folder. You can install the Seattle .ipk using "opkg install " on the router.
