SONIC Source Code Compilation

[sarthakg0191]

I am compiling the SONIC source code in my Ubuntu 22.04 system by issuing the following commands
make ini,
make configure PLATFORM=vs,
make SONIC_BUILD_JOBS=4 all)
just to see whether I am able to compile or not but it is giving error in compilation. Can anybody tell me the right steps to compile so that it will be compiled successfully?
As I am exploring about SONIC so I don't know much about it so I will be grateful if anyone is ready to help me.

Before you wish to setup the repo make sure you have the correct hardware requirements as mentioned in the README.md:

Multiple cores to increase build speed
Plenty of RAM (less than 8 GiB is likely to cause issues)
300G of free disk space
KVM Virtualization Support.

Once you have that the steps to build the repo are as follows:
sudo modprobe overlay
git checkout master
git submodule update --init --force --recursive
make init
make configure PLATFORM=vs

Now you can run make list and you will get a number of debian (.deb) and wheel (.whl) targets. Based on the section you want to work on, choose the relevant target. For example when working with sonic-utilities:

make NOSTRETCH=1 NOBUSTER=1 NOBULLSEYE=1 KEEP_SLAVE_ON=yes target/python-wheels/bookworm/sonic_utilities-1.2-py3-none-any.whl

This will get you within the slave docker, then you can run:
cd src/sonic-utilities/
python3 setup.py bdist_wheel

That is it, now you can modify the code and run unit tests. Most tests in SONiC are written using the pytest framework and have the setup.py file. You can use python3 setup.py test to run them.

I would also like to know if there's a confirmed distro that works for building the image from source. I've been trying building for broadcom and vs, on a physical machine, on a VM, in Ubuntu 22 LTS, Ubuntu 23. Got different errors every time, such as building all with -j4 would fail some targets and I had to build that single target only.
However the Azure pipeline is passing so I can only guess it's inconsistency between build machines.

Here are the OS and firmware versions of my VM on which I have successfully built sonic:

CPE OS Name: cpe:/o:almalinux:almalinux:9::baseos
Kernel: Linux 5.14.0-427.13.1.el9_4.x86_64
