Please install clang or check configuration `clang.executable

As an AI language model, I don't have access to your system to install any software. However, I can provide you with some general guidance on how to install clang and configure it.

1. Installing Clang on Ubuntu:

Open your terminal and run the following command to install clang.

sudo apt install clang

2. Installing Clang on macOS:

You can install Clang on macOS using Homebrew. Open your terminal and run the following command.

brew install llvm

3. Configuring Clang:

After installing Clang, you need to configure it to use it with your application. You can do this by setting the Clang executable path in your project configuration file.

For example, in CMake, you can set the Clang executable path using the following command:

set(CMAKE_CXX_COMPILER /usr/bin/clang++)

If you are using an IDE, you can set the Clang executable path in the project settings.

Once you have installed and configured Clang, you can use it to compile your code.
