TPLink Archer c7 build issue

For Developers
1

Hi,
I am trying to convert my TPlink Archer c7 v2.0 router to SDN enabled one using OpenWRT+OpenFlow. I am new to this area. I was successful in installing the OpenWRT image in the router. But when I tried to add the OpenFlow feature and build, it is giving me error.

Steps followed:

git clone https://git.lede-project.org/source.git lede
cd lede
./scripts/feeds update -a
./scripts/feeds install -a
cd ~/lede
git clone https://github.com/CPqD/openflow-openwrt.git
cd ~/lede/package/
ln -s ~/lede/openflow-openwrt/openflow-1.3/
cd ~/lede
ln -s ~/lede/openflow-openwrt/openflow-1.3/files

make menuconfig
Network > openFlow
[*]Network > tc
Kernel Modules > network support > kmod-tun
save and exit
make V=s

I tried it in 2 ways.

  1. By specifically selecting the tag lede v17.01 .
    git tag
    git checkout lede-17.01
  2. Without mentioning the tag so that it will take the latest version.
    [left fig] without mentioning any tags [right fig] with tag lede-17.01

error

Has anyone encountered a similar issue? Is there a known fix ?

Regards,
Pournami

Build instructions aren't the clearest at https://github.com/CPqD/ofsoftswitch13/wiki/OpenFlow-1.3-for-OpenWRT, are they!

On the left it looks like the build system can't verify the integrity of the package. MD5 or SHA256 in the line there that I spotted. Looks like an outdated Makefile in need of either PKG_MD5SUM or PKG_SHA256SUM

Some good info on a current package's Makefile at https://openwrt.org/docs/guide-developer/packages and Packaging guidelines

If you can, in the future, paste the error messages into ``` wrappers (code-block Markdown), they'd be a lot easier to read.
