This change is tied to the ROCclr cmake rework. ROCclr will now be built as part of OpenCL itself. All the dependencies on comgr and rocr have been moved into ROCclr itself. This allows OpenCL to pull in all the required compiler/runtime dependencies by simply linking against ROCclr. Note that ROCclr needs to be configured from OpenCL cmake command line. If not, we will default to LC + ROCr support. Change-Id: I5271302d073aef8cfa617828d218c856711bf9ba

Getting the source code
Download the git projects using the following commands:
git clone -b main https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git
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, 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, rocm-4.1, etc.
Setup OpenCL
Copy the amdocl64.icd file to /etc/OpenCL/vendors
sudo cp api/opencl/config/amdocl64.icd /etc/OpenCL/vendors/
Building
Follow these steps:
-
Build ROCclr first. Follow the steps in the following link to build ROCclr ROCclr Readme In this step, $OPENCL_DIR and $ROCclr_DIR are defined.
-
Building OpenCL Run these commands:
cd "$OPENCL_DIR"
mkdir -p build; cd build
cmake -DUSE_COMGR_LIBRARY=ON -DCMAKE_PREFIX_PATH="$ROCclr_DIR/build;/opt/rocm/" ..
make -j$(nproc)
Note: For release build, add "-DCMAKE_BUILD_TYPE=Release" to the cmake command line.
