# ROCclr - Radeon Open Compute Common Language Runtime
|
|
ROCclr is a virtual device interface that compute runtimes interact with to different backends such as ROCr or PAL
|
|
This abstraction allows runtimes to work on Windows as well as on Linux without much effort.
|
|
|
|
## Repository branches
|
|
The repository maintains several branches. The branches that are of importance are:
|
|
|
|
- master: This is the default branch.
|
|
|
|
## Building
|
|
|
|
### Prerequisites
|
|
|
|
- Install mesa-common-dev
|
|
- Either build or install [COMGR](https://github.com/RadeonOpenCompute/ROCm-CompilerSupport), [CLANG](https://github.com/RadeonOpenCompute/llvm-project) and [Device Library](https://github.com/RadeonOpenCompute/ROCm-Device-Libs)
|
|
|
|
### Getting the source code
|
|
|
|
```bash
|
|
git clone https://github.com/ROCm-Developer-Tools/ROCclr.git
|
|
git clone -b master-next https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git
|
|
```
|
|
|
|
### Set the environment variables
|
|
|
|
```bash
|
|
export ROCclr_DIR="$(readlink -f ROCclr)"
|
|
export OPENCL_DIR="$(readlink -f ROCm-OpenCL-Runtime)"
|
|
```
|
|
|
|
### Build ROCclr
|
|
Here is command to build ROCclr:
|
|
|
|
```bash
|
|
cd "$ROCclr_DIR"
|
|
mkdir -p build; cd build
|
|
cmake -DOPENCL_DIR="$OPENCL_DIR" -DCMAKE_INSTALL_PREFIX=/opt/rocm/rocclr ..
|
|
make -j$(nproc)
|
|
```
|
|
|
|
### Optional steps to build HIP runtime
|
|
Enter the directory where git cloned the ROCClr and OpenCL. Run the following commands:
|
|
|
|
```bash
|
|
git clone -b master-next https://github.com/ROCm-Developer-Tools/HIP.git
|
|
export HIP_DIR="$(readlink -f HIP)"
|
|
cd "$HIP_DIR"
|
|
mkdir -p build; cd build
|
|
cmake -DHIP_COMPILER=clang -DHIP_PLATFORM=rocclr -DCMAKE_PREFIX_PATH="$ROCclr_DIR/build" ..
|
|
make -j$(nproc)
|
|
```
|
|
|
|
### Release build
|
|
For release build, add "-DCMAKE_BUILD_TYPE=Release" to the cmake command line.
