Downloading Llvmenv

Next, you will clone the Llvmenv repository from GitHub. Run the following command:

“`bash
git clone https://github.com/llvmenv/llvmenv.git ~/.llvmenv
“`

This command clones the Llvmenv repository into a hidden directory in your home folder.

Setting Up Environment Variables

To make Llvmenv accessible from the command line, you need to add it to your shell configuration. Depending on the shell you are using (Bash, Zsh, etc.), add the following lines to the appropriate configuration file:

  • For **Bash** (usually `~/.bashrc`):

“`bash
echo ‘export LLVMPATH=”$HOME/.llvmenv”‘ >> ~/.bashrc
echo ‘export PATH=”$LLVMPATH/bin:$PATH”‘ >> ~/.bashrc
source ~/.bashrc
“`

  • For **Zsh** (usually `~/.zshrc`):

“`bash
echo ‘export LLVMPATH=”$HOME/.llvmenv”‘ >> ~/.zshrc
echo ‘export PATH=”$LLVMPATH/bin:$PATH”‘ >> ~/.zshrc
source ~/.zshrc
“`

This configuration sets up the necessary environment variables for Llvmenv.

Verifying the Installation

After completing the installation, you should verify that Llvmenv is correctly set up. Run the following command in your terminal:

“`bash
llvmenv –version
“`

If the installation was successful, this command will display the version of Llvmenv installed on your system.

I’m Leonard a developer by trade, a problem solver by nature, and the person behind every line and post on Freak Learn.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
