Clang is a high-performance C, C++, and Objective-C compiler and toolset. Clang is an open-source project developed by the LLVM project. Clang-compiled programs are very fast and efficient. Clang also has amazing code optimization capabilities. To make the identification of errors and fixing of code issues easier for developers, Clang provides better error messages and diagnostics. Clang is a good alternative to the GCC compiler and toolset.
In this article, we will show you how to install the LLVM Clang C, C++, and Objective-C compiler on Debian 12.

As you can see, Clang C, C++, and Objective-C compilers are accessible on our Debian 12 system. We have the Clang version 14 installed on our Debian 12 system.
Installing Other Versions of Clang C/C++ Compiler on Debian 12
On Debian 12, Clang 14 is installed by default as you’ve seen in the earlier section of this article. But Clang 13 and Clang 15 are available in the official package repository of Debian 12 as well.
To install Clang 13 on your Debian 12 system, run the following command:
To install Clang 15 on your Debian 12 system, run the following command:
To confirm the installation, press Y and then press <Enter>.
Your desired version of Clang and the required dependency packages are being downloaded. It takes a while to complete.
Your desired version of Clang is being installed. It takes a while to complete.
At this point, your desired version of Clang C, C++, and Objective-C compiler should be installed on your Debian 12 system.
If you installed Clang 15, you can check whether you can access Clang 15 C, C++, and Objective-C compiler with the following commands:
$ clang-15++
If you installed Clang 13, you can check whether you can access Clang 13 C, C++, and Objective-C compiler with the following commands:
$ clang-13++
