Minimal build system

[anon20279570]

I would like to have minimal openwrt folder where i build my openwrt.
I always run make dirtclean after i build new firmware for my router. After running ./scripts/feeds update -a && ./scripts/feeds install -a Current openwrt folder is at 510M.

To reduce it i clone openwrt with this command git clone --depth 1 https://git.openwrt.org/openwrt/openwrt.git and after previous command update & install feeds openwrt folder is just 262 MB

But i get errors like these every time i try make menuconfig or update or install feeds. Does this mean that it needs older commit info? And why is it needed to just build firmware?

And why is it needed to just build firmware?

To calculate the version with ./scripts/getver.sh

The string like OpenWrt SNAPSHOT r12106-c6c4701def
The "r12106" portion is the number of commits since ee53a240

https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=scripts/getver.sh;h=9175f411db8345ab420fdb1edcaf0d20f858f12f;hb=HEAD

Thanks. So my firmware will have version "unknown" if i won't have whole .git folder with all commits since ee53a240 right?

Yep.
or simply have a file "version" with some content like "My own OpenWrt", and that will be preferred as the version (as "try_version" is evaluated first)

Or edit the git inquire functions used in scripts/getver.sh and simplify it.
