Hey everyone, I hope someone can help me out here! So, I’ve been diving into some C/C++ development and I’ve heard a lot of good things about Clang, especially the latest version, Clang 18. I recently switched to Ubuntu, and while I’m getting the hang of things, I’ve hit a bit of a roadblock when it comes to installing Clang.
I’ve tried looking for tutorials online, but they all seem to skip some steps or assume a level of expertise that’s a bit above where I’m at right now. I’m looking for a simplified breakdown of how to get Clang 18 up and running on my Ubuntu system.
I really want to avoid messing up my system or running into dependency hell, so I’m hoping that someone can guide me through the whole process. For starters, details on whether I need to do any special preparations before starting the installation would be awesome.
Also, are there any dependencies or packages that I need to install beforehand? I’ve heard that using the terminal can be a bit tricky if you’re not familiar with it, so any command lines or steps you can provide would be appreciated.
What should I do first? Should I add any repositories or is it available in the default package manager? Also, after installation, how do I check if everything worked? Like, are there specific commands I can run to see if Clang 18 is correctly set up?
Lastly, if there are any common pitfalls or mistakes I should avoid while installing, please lay them out for me. I’d really like to avoid having to start over or dealing with broken packages because I missed a step or two.
Thanks a bunch in advance! I’d be super grateful for a step-by-step guide, or even just some pointers, so that I can get up and running with Clang 18 without too much hassle.
