[Cerowrt-devel] ar71xx CC builds and tc

[Matt Taggart]

Hi,

I have installed a bunch of wndr3800's in the last few days with CC and
noticed a couple things:

1) sometime around Aug 11 the ar71xx-generic builds jumped from having a
date of mid july and using a 3.18 kernel, to having a Aug 11 date and
4.1.4 kernel. I guess builds weren't working and then got fixed? Anyway
maybe a good time for people to test newer builds.

2) CC doesn't seem to include tc by default now, so when I installed
luci-app-sqm (which pulls in sqm-scripts) things weren't working
correctly. After I installed tc then it started working. Toke, maybe
you need to have sqm-scripts start depending on tc?

Thanks,

Ah, right. It does have a dependency for tc, but I changed it to allow
substituting the tc-adv package instead. However, this seems to only be
picked up by the build system, not the ipkg dependency list, so package
installation won't pull in tc.

Reverted back to just depending on the tc package in the openwrt feed
now. Should be picked up after the next nightlies appear. Thanks for
spotting this! :)

Hi,

On trunk with ceropackages, I'm getting errors when installing sqm-scripts:

root@OpenWrt:/etc# opkg install sqm-scripts
Installing sqm-scripts (1.0-3) to root...

The way I built it was:
git clone git://git.openwrt.org/openwrt.git
cd openwrt/
cp feeds.conf.default feeds.conf
sed -i '1s/^/src-get cero https:\/\/github.com\/dtah\/ceropackages-3.10.git\n/'
feeds.conf
./scripts/feeds update -a
./scripts/feeds install luci luci-app-sqm sqm-scripts tc-adv ip ethtool
kmod-sched-cake kmod-sched-fq_pie
make menuconfig    #select wndr3800 and save
screen
make V=99

Flash a factory image.

trunk is running 4.1.5:
root@OpenWrt:/etc# uname -a
Linux OpenWrt 4.1.5 #2 Sat Aug 15 20:32:44 CEST 2015 mips GNU/Linux

Best regards,
Maciej

It looks like this is pulling in the package from the openwrt snapshots
repo.

This is a kernel version mismatch issue. Unfortunately, when a package
depends on a kernel module, the build system makes the dependency be for
a specific version of the kernel, so you can't just pull packages from
incompatible repos.


To get your self-built version of the package onto the router, you can
do one of:

1. Select it in menuconfig to be built into the image as you generate it
   (press Y). Then it will be included as you flash.

2. Manually SCP the .ipk from bin/ar71xx/packages/cero/ to the
   router after flashing, then installing with opkg.

3. Make the contents of bin/ar71xx/packages available on a web server
   and point the opkg.conf on your router at that.
