Repository branches

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

• Main branch: This is the stable branch. It is up to date with the latest release branch, for example, if the latest ROCM release is rocm-4.1.x, main branch will be the repository based on this release.
• Release branches. These are branches corresponding to each ROCM release, listed with release tags, such as rocm-4.0.x, rocm-4.1.x, etc.

Building

Prerequisites

• Install mesa-common-dev
• Either build or install COMGR, CLANG and Device Library

Getting the source code

git clone -b main https://github.com/ROCm-Developer-Tools/ROCclr.git
git clone -b main https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git

Set the environment variables

export ROCclr_DIR="$(readlink -f ROCclr)"
export OPENCL_DIR="$(readlink -f ROCm-OpenCL-Runtime)"

Build ROCclr

Here is command to build ROCclr:

cd "$ROCclr_DIR"
mkdir -p build; cd build
cmake -DOPENCL_DIR="$OPENCL_DIR" -DCMAKE_INSTALL_PREFIX=/opt/rocm/rocclr ..
make -j$(nproc)
sudo make install

Optional steps to build HIP runtime

Enter the directory where git cloned the ROCClr and OpenCL. Run the following commands:

git clone -b main https://github.com/ROCm-Developer-Tools/HIP.git
export HIP_DIR="$(readlink -f HIP)"
cd "$HIP_DIR"
mkdir -p build; cd build
cmake -DCMAKE_PREFIX_PATH="$ROCclr_DIR/build;/opt/rocm/" ..
make -j$(nproc)

Release build

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