## Getting the source code
|
||
Download the git projects using the following commands:
|
||
|
||
```bash
|
||
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
|
||
|
||
```bash
|
||
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](https://github.com/ROCm-Developer-Tools/ROCclr)
|
||
In this step, $OPENCL_DIR and $ROCclr_DIR are defined.
|
||
|
||
- Building OpenCL
|
||
Run these commands:
|
||
|
||
```bash
|
||
cd "$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.
