Build instructions

Requirements

• Working C and C++ toolchains(compiler, linker)
• cmake
• make or ninja

0. Clone Polygeist

git clone --recursive https://github.com/wsmoses/Polygeist.git
cd Polygeist

1. Install LLVM, MLIR, Clang, and Polygeist

Option 1: Using pre-built LLVM, MLIR, and Clang

Polygeist can be built by providing paths to a pre-built MLIR and Clang toolchain.

1. Build LLVM, MLIR, and Clang: ```sh mkdir llvm-project/build cd llvm-project/build cmake -G Ninja ../llvm \

-DLLVM_ENABLE_PROJECTS=”mlir;clang”
-DLLVM_TARGETS_TO_BUILD=”host”
-DLLVM_ENABLE_ASSERTIONS=ON
-DCMAKE_BUILD_TYPE=DEBUG ninja ninja check-mlir

2. Build Polygeist:
```sh
mkdir build
cd build
cmake -G Ninja .. \
  -DMLIR_DIR=$PWD/../llvm-project/build/lib/cmake/mlir \
  -DCLANG_DIR=$PWD/../llvm-project/build/lib/cmake/clang \
  -DLLVM_TARGETS_TO_BUILD="host" \
  -DLLVM_ENABLE_ASSERTIONS=ON \
  -DCMAKE_BUILD_TYPE=DEBUG
ninja
ninja check-mlir-clang

Option 2: Using unified LLVM, MLIR, Clang, and Polygeist build

Polygeist can also be built as an external LLVM project using LLVM_EXTERNAL_PROJECTS.

1. Build LLVM, MLIR, Clang, and Polygeist: ```sh mkdir build cd build cmake -G Ninja ../llvm-project/llvm \

-DLLVM_ENABLE_PROJECTS=”clang;mlir”
-DLLVM_EXTERNAL_PROJECTS=”polygeist”
-DLLVM_EXTERNAL_POLYGEIST_SOURCE_DIR=..
-DLLVM_TARGETS_TO_BUILD=”host”
-DLLVM_ENABLE_ASSERTIONS=ON
-DCMAKE_BUILD_TYPE=DEBUG ninja ninja check-mlir-clang
