LLVM 21.1.1 on Fedora 41

This is my fork of LLVM 21.1.1 from https://llvm.org/ on Fedora 41. It builds with Fedora's GCC 14.3.1 and Python 3.13. You will need to install some dependencies: z3, libxml2, ocaml.

The main branch is the canonical release from LLVM upstream, unmodified. The branch llvm-21.1.1-fc41 is the Fedora 41 branch containing my changes.

Build scripts are in the build-scripts directory in the llvm-21.1.1-fc41 branch.

Build and Install Instructions:

1. Clone this repo.
2. %> mkdir build-llvm
3. %> mkdir install-llvm
4. %> cp ./llvm-21.1.1/build-scripts/run-cmake-configure-linux.sh ./build-llvm/
5. %> cp ./llvm-21.1.1/build-scripts/build-llvm.sh ./build-llvm/
6. %> cp ./llvm-21.1.1/build-scripts/install-llvm.sh ./build-llvm/
7. %> cd ./build-llvm
8. %> ./run-cmake-configure-linux.sh
9. %> ./build-llvm.sh
10. %> ./install-llvm.sh

This build of LLVM will install in the install-llvm directory created above.

The original README.md file has been renamed to LLVM.README.md.

I put this clone here because several of my other ports / forks at my Github depend on LLVM 21.1.1.

You can find the RPM spec files for Fedora 41 in the same build-scripts directory.
