Incorrect links in staging_dir

Installing and Using OpenWrt
1

I am compiling the latest snapshot and get an error. It seems that the python3 link in my staging_dir points to python3.10, but my system switched to python3.11 already. How do I fix the links in staging_dir?

:~/openwrt> uname -a
Linux blaq 6.3.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 11 May 2023 16:40:42 +0000 x86_64 GNU/Linux
:~/openwrt> ls -la /usr/bin/python3*
lrwxrwxrwx 1 root root    10 Apr  5 16:52 /usr/bin/python3 -> python3.11
-rwxr-xr-x 1 root root 14280 Apr  5 16:52 /usr/bin/python3.11
-rwxr-xr-x 1 root root  3248 Apr  5 16:52 /usr/bin/python3.11-config
lrwxrwxrwx 1 root root    17 Apr  5 16:52 /usr/bin/python3-config -> python3.11-config

I proceed to update OpenWrt as follows:

:~/openwrt> git pull
Already up to date.
:~/openwrt> make menuconfig
:~/openwrt> ./scripts/feeds update -a && ./scripts/feeds install -a && make -j1 V=sc

I look at the cause of the error:

Same issue as in Faulty build after moving to a new laptop

mhhh it seems the problem is that prereq is dereferencing the link instead of referencing the generic python3 link... we got a similar problem with another user on IRC. Can you by chance create an issue on github and tag me so we can track it there?

I followed the recommendations from this link and it solved my issue.

:~/openwrt> mv staging_dir/host/.prereq-build staging_dir/host/.prereq-build.old
:~/openwrt> make prereq
:~/openwrt> ls -la staging_dir/host/bin/python3*
