Have you seen the recently updated Modernized set for Ubuntu 22.04 for OpenWrt master, 22.03 and 21.02 branches that do not need python2.7 any more. Python3 is installed by default in Ubuntu22.04.
Just remembered I had all kind of issues with newer Ubuntu versions, I had switched so Debian, much faster and way less buggy.
However setting up Debian is a little messy, so I made a backup in ready state and uploaded to Drive have a backup, you can also use it!
It has arm-linux-gnueabi-gcc installed, but it's irrelevant, that was for a different hardware, different project, doesn't affect Openwrt at all.
Turned out to be a great building machine for it, I might have compiled Openwrt 22.03 no less than 50 times in it!
Otherwise try an older Ubuntu x64 version, like 16.04, which has older kernel, and install these packages:
# Install stuff
sudo apt update && sudo apt install -y wget unzip build-essential rsync git bc swig libncurses-dev libacl1-dev libpython3-dev libssl-dev python3-distutils git cmake autoconf u-boot-tools bison flex
# Optional if you're using Virtualbox and want to install Guest Additions
sudo apt install linux-headers-$(uname -r)
Then just:
git clone https://github.com/openwrt/openwrt --recursive -b openwrt-22.03 openwrt-22.03
cd openwrt-22.03
scripts/feeds update -a
scripts/feeds install -a
make defconfig
make menuconfig
# Select your targets etc, save config..
# Replace number with CPU cores+1,
# Ex. for 8 cores:
make -sj9
# This will take a while!
Are you using a real computer or virtual installations in any form?
I have had no problems building OpenWrt images with either Ubuntu 21.02 or recently upgraded to Ubuntu 22.04. But this is primary and only installation on a real computer.
The only OpenWrt build problem I repeatedly seem to have over time is download servers often in Cambridge doesn’t answer on weekends.
With any decent quadcore CPU with <10 years which has virtualization and at least 8GB RAM, VM should work great.
In the end it's almost the same thing as a real machine, but much easier and safer to handle, backup and maintain.
Remember to enable Virtualization in the Bios or It work extremely slow, if using Windows disable Hyper-V or Virtualbox won't stop crashing, freezing and displaying all kind of strange errors.
I already gave you everything to start compiling, couldn't be easier, now is up to you what to do!
Not really.
How is a driver going to cause a compilation error? It's unrelated.
It's often caused by upgraded libraries/tools, breaking compatibility with older code.
Edit:
Openwrt 21.02 also compiled perfectly in that Debian machine!
