Comment 0 for bug 2051457

Since Jammy went to the 6.5.0 kernel series, that kernel series was complied with gcc-12. The previous 6.2.0 series kernels were complied with gcc-11.

The current version of gcc in jammy is 11.4.

Many NVidia drivers, wifi drivers, VirtualBox (from our Repo), etc fial to build the modules, because of a gcc compiler version mismatch between what the current running kernel was built by, and the module being built.

I recognized this while helping Users with NVidia driver compile errors on the forum, and came up with this work-around for them:
https://ubuntuforums.org/showthread.php?t=2494273&p=14175164#post14175164

Summary:
Install gcc-12 & g++-12 on 22.04.3 and use it as the compiler.

Since then, this work-around has helped to resolve problems with running the 6.5.0 series kernels and building modules for other applications and hardware drivers: VirtualBox, WiFi Drivers, etc. for use with the 6.5.0 series.

I have run this for over a month as my default with no ill affects. I have continued to recommend this work-around to many user to solve their problems...

*** I think it is time to look at pushing through gcc-12 as the default compiler for 22.04.3 through the normal updates channel.
