Error while installing Cilk Plus on Mac OS X (El Capitan)

Question

I have encountered issues while installing the CilkPlus on my Mac OS X.Following the installation page, I have executed the following commands in the following order:

$mkdir Cilk
$cd Cilk
$git clone -b cilkplus https://github.com/cilkplus/llvm llvm
$git clone -b cilkplus https://github.com/cilkplus/clang llvm/tools/clang
$git clone -b cilkplus https://github.com/cilkplus/compiler-rt llvm/projects/compiler-rt

Then,

$cd llvm    
$mkdir build && cd build
$cmake -G "Unix Makefiles" -DINTEL_SPECIFIC_CILKPLUS=1 --DCMAKE_INSTALL_PREFIX=/Binary2 -DCMAKE_BUILD_TYPE=Release \ -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ..

However, it ended with errors.ErroLog ErrorLog3. It would be great if someone can let me know where I am wrong. I am trying to compile and execute CilkPlus code.

Answer 1

It looks like your c++ compiler cannot compile/run this check.

#include <atomic>
std::atomic<int> x;
int main() {
  return x;
}

It would be a good starting point to check if your system has the latest compilers and Xcode.
