How to set the LLVM_HOME?

[peterhchen]

export LLVM_HOME=/path/to/your/llvm/installation

1. What is "/llvm/installation" example?
2. Do we have to build "llvm/installation"?
3. Can you give us the link of step-by-step how to build "llvm/installtion"?

Thanks,
Peter H. Chen

I recommend you use the Docker image. Installing LLVM-Tracer and LLVM on a regular machine has been notoriously difficult and riddled with system-specific errors that are hard for us to diagnose and debug.

To answer your question: you will need to build and install LLVM and Clang from source. The Dockerfile shows how it is done here, but you can also just follow their installation instructions on the LLVM website.
