Cannot satisfy dependencies after firmware build

[wei48221]

I followed the instructions at https://github.com/MediaTek-Labs/linkit-smart-7688-feed and https://forum.labs.mediatek.com/en/t/adventures-in-building-openwrt-for-linkit7688/258 to compile firmware and installed the new firmware on my LinkIt Smart 7688 Duo successfully.

root@mylinkit:~# uname -r
3.18.44

However, when following the instruction at https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/tutorials/file-storage/mounting-the-root-fs-on-an-sd-card, I run into the below problem after running "opkg update" and "opkg install kmod-fs-ext4"

Installing kmod-fs-ext4 (3.18.23-1) to root...

Could you someone point me a direction to solve this issue? Thanks!!

The kernel module kmod-fs-ext4 will need to to built for the specific kernel that you are using.

This is an interesting twist that I did not consider. The short term solution is to use makemeuconfig to add this module to your build. A long-term solution is to make a repo to download images based on different kernels and include a repo with good amount of packages.

Thanks for the prompt reply!!

Is it possible for you to give some examples on how to do make menuconfig to add this module to my build (for example, where to get the source for kmod-fs-ext4 and how to add it to my build)?

See the make menuconfig section on this page:

Thanks! I've successfully added the 2 modules and compiled a new firmware that works..
