1. BUILDING:

To distribute applications that use the Cilk language extensions to non-development systems, you need to build the Cilk runtime library and distribute it with your application. This instruction describes the build process using CMake*, which supports Linux*, and OS X*.

You need the CMake tool and a C/C++ compiler that supports the Cilk language extensions. The requirements for each operating systems are:

• Common: CMake 3.4.3 or later Make tools such as make
• Linux: Tapir/LLVM compiler, or GCC* 4.9.2 or later (depracated), or Cilk-enabled branch of Clang*/LLVM* (http://cilkplus.github.io), or Intel(R) C++ Compiler v12.1 or later (depracated)
• OS X: Tapir/LLVM compiler, or Cilk-enabled branch of Clang*/LLVM* (http://cilkplus.github.io), or Intel C++ Compiler v12.1 or later (depracated)

The common steps to build the libraries are 1) invoke cmake with appropriate options, 2) invoke a make tool available on the system. The following examples show build processes on Linux/OS X.

Linux/OS X:

$ mkdir ./build && cd ./build
$ cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
        -DCMAKE_INSTALL_PREFIX=./install ..
$ make && make install

2. USING:

The Tapir/LLVM compiler requires an explicit compiler option, -fcilkplus, to enable Cilk language extensions. For example,

$ clang -fcilkplus -o foo.exe foo.c 

3. DOXYGEN DOCUMENTATION:

The library source has Doxygen markup. Generate HTML documentation based on the markup by changing directory into runtime and running:

$ doxygen doxygen.cfg

4. QUESTIONS OR BUGS:

Issues with this Cilk runtime can be addressed on the Cilk Hub website on GitHub: https://github.com/CilkHub/cilkrts/
