## Getting the source code
Download the git projects using the following commands:

```bash
git clone -b develop https://github.com/ROCm/clr.git
export CLR_DIR="$(readlink -f clr)"
```

## Repository branches

The repository maintains several branches. The branches that are of importance are:

- Develop branch: This is the default branch, on which the new features are still under development and visible. While this maybe of interest to many, it should be noted that this branch and the features under development might not be stable.
- Release branches: These are branches corresponding to each ROCM release, listed with release tags, such as rocm-6.0.x, rocm-5.7.x, etc.

## Setup OpenCL
Copy the amdocl64.icd file to /etc/OpenCL/vendors

```bash
sudo cp api/opencl/config/amdocl64.icd /etc/OpenCL/vendors/
```

## Building

Run these commands:

```bash
cd "$CLR_DIR"
mkdir -p build; cd build
cmake -DCMAKE_PREFIX_PATH="/opt/rocm/" -DCLR_BUILD_HIP=OFF -DCLR_BUILD_OCL=ON ..
make -j$(nproc)
```

Note: For release build, add "-DCMAKE_BUILD_TYPE=Release" to the cmake command line.
