Using Bullseye X64 taken from the raspberry site, I am compiling large-ish programs in C using gcc and this is producing many warning that is causing the created programs not to work so I want to install clang.
The issue with gcc always seems to appear when every that produce a later version :(
Using the repos and the package manager it cannot find clang and I cannot work out how to get it for the Pi4,
I have run clang in place of gcc on other platforms which gets around the issues with gcc so I am hoping it will fix the issue.
Can anyone help in getting clang on the Pi4 ?

Does apt list clang show nothing at all?

Its definitely available, I've been using in 64 bit containers on the Pi for years, its often gives slightly better performing ARMv8 code than gcc (default options on both).

Did you do an apt update first? But even if you didn't, it's been there for years, like druck said. On my raspios64 installation:

For no apparent reason the original was sent as base64 encoded, but thunderbird here displays it normally, I had to view source to see what you did.

It does have ROT-4 what ever that is - never used it.

AFAIK, Usenet does not require that MIME encoded messages are supported.
So it should not have been encoded in the first place. That some clients
- mainly those that are also Mail clients, which does support Mime - are able to decode it is just luck.

On the Pi3 and 32 bi, yes I have installed clang. The problem is with the 64 bit version.
This is teaching me that I really should be using Linux and not Debian.

That's weird. You'd think you'd at least be able to install the 32 bit clang.

What do you consider "Linux"? Ubuntu? That's based off of Debian -- but Debian tends to lock down software packages until proven; Ubuntu tends to be "bleeding edge" making all new packages available as soon as they get it compiled.
Red Hat or Fedora? Different package managers, but probably still the same OS core. Antique Mandrake/Mandriva -> Mageia

Hat derivatives).
Maybe download the .DEB file and manually install it?

Linux is a kernel nothing more.
There are many operating systems using Linux for a kernel, Debian is one such, Android is another, OpenWRT yet another. Most of the unixlike ones use the tools from the GNU project and a selection of other open source software to build a complete operating system around the kernel - many of the smaller ones use busybox instead but some, like the OS that runs many cheap smart TVs, look nothing like unix despite their Linux kernel.

Definitely.
Red Hat (aka RHEL) is the LTS version, with paid-for support if you want that. Fedora is its free, more bleeding, edge equivalent.
I've used Fedora since it first replaced Red Hat 6.x, somewhere around
2005 and would only use RHEL of I was a commercial operation.
I prefer Red Hat to Debian and its derivatives mainly because I find the RH package manager (dnf) easier to use than Debian's apt and friends, but of course ymmv. The log dnf generates during an upgrade is a lot better formatted and easier to read than apt's output.

Raspberry Pi OS 64-bit has clang. Either you don't have Raspberry Pi OS, or it is some other problem on your end. We all have it.

If you're using Debian then you are using Linux.

Should have said a formal version of Linux i.e., vis RH.
There are a few differences with Debian, at least with he one used for Raspberry h/w. The lack of up to date (or at all) packages on it. I also notice a difference of what is available between Intel/AMD h/w and the Pi.
It is a shame that my attempts to use Ubuntu for the Pi failed both server and desktop when I tried to build the Pi4 SSD some months back.
The Pi builds are some what related to schools, colleges etc as well as children's first computer et al so they are no whay near as complete as standard distro's as near as I can tell.
Major point, when I got to be 70 my patience for such problems has reduced, and now I am 75+ its even less :) I just want it to work - well more or less, period. I expect to have to build the odd app but not the basics !

Sorry, no idea why my copy of Thunderbird chose to do that then, I assume it doesn't normally.
