Building a standalone copy of the OpenCilk tools

These instructions assume that you are building the OpenCilk tools using the OpenCilk compiler.

Building with CMake

1. Make a build directory at the top level and enter it:

   mkdir build
   cd build

2. Configure CMake. Make sure to specify CMAKE_C_COMPILER, CMAKE_CXX_COMPILER, and LLVM_CMAKE_DIR to point to the corresponding build or installation of the OpenCilk compiler binaries. In addition, set CMAKE_BUILD_TYPE to specify the build type, such as, Debug, for an unoptimized build with all assertions enabled; Release, for an fully optimized build with assertions disabled; or RelWithDebInfo, to enable some optimizations and assertions. (The default build type is Debug.)

   Example configuration:

   cmake -DCMAKE_C_COMPILER=/path/to/opencilk-project/build/bin/clang -DCMAKE_C_COMPILER=/path/to/opencilk-project/build/bin/clang++ -DCMAKE_BUILD_TYPE=Release -DLLVM_CMAKE_DIR=/path/to/opencilk-project/build ../
   

3. Build the runtime:

   cmake --build . -- -j<number of build threads>

To clean the build, run cmake --build . --target clean from the build directory.
