Set up environment on Mac OS

Mac support is still experimental. Submit bugs if you experience issues.

  1. Run terminal.

  2. Install homebrew (if haven't already) following instructions from here:

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile\n

  3. Install clang-15 compiler (make sure that the version is not older than 15):

    brew install llvm
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
export CC=clang
export CXX=clang++

    Consider making environment changes permanent:

    echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
echo 'export CC=clang' >> ~/.zshrc
echo 'export CXX=clang++' >> ~/.zshrc

  4. Build release version of google benchmark library. It doesn't matter which compiler you use to build it. Install google benchmark library with:

    git clone https://github.com/google/benchmark.git
cd benchmark
git clone https://github.com/google/googletest.git
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --config Release --target install

  5. Go to any lab and check if local lab builds are working. You can find the CMake commands here.

  6. (Optional) Install ninja.

    $ brew install ninja

    You can use it to build labs by passing -G Ninja to the CMake invocation.
