How can install the libc properly?

Installing and Using OpenWrt

The package libc can't be installed directly with opkg install.

root@OpenWrt:~# opkg update
root@OpenWrt:~# opkg install  libc
Unknown package 'libc'.
Collected errors:
 * opkg_install_cmd: Cannot install package libc.

So i have to install it manually.

root@OpenWrt:~#     wget  https://downloads.openwrt.org/releases/19.07.7/targets
/x86/64/packages/libc_1.1.24-2_x86_64.ipk

Why can't locate it ?

root@OpenWrt:~# which libc
root@OpenWrt:~# find / -name 'libc'

It's rather simple, you can't. Neither kernel, nor libc are packaged (and just provide empty meta-packages for dependency resolutions); sysupgrade to a newer image build.
