Dependencies

• C++20
• CMake 3.14+

Instructions: Linux/Ubuntu/GCC

Check your GCC version:

g++ --version

The output should be something like:

g++-8 (Ubuntu 8.4.0-1ubuntu1~18.04) 8.4.0

If you see a version before GCC-10, update it with

sudo apt update
sudo apt install gcc-10
sudo apt install g++-10

Once you installed a newer version of GCC, you can link it to update-alternatives. For instance, if you have GCC-7 and GCC-10, you can link them with:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 7
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10

You can now use update-alternatives to set your default gcc and g++ to a more recent version:

update-alternatives --config g++
update-alternatives --config gcc

Also check your CMake version:

cmake --version

If it’s older than CMake 3.14, update it with

sudo apt upgrade cmake

or download the most recent version from cmake.org.

Later when running CMake, make sure you are using GCC-8 or higher by appending the following options:

-DCMAKE_C_COMPILER=/usr/bin/gcc-10 -DCMAKE_CXX_COMPILER=/usr/bin/g++-10

Instructions: Mac Os/Clang

Check your Clang version:

clang --version

The output should have something like

Apple clang version 11.0.0

If you see a version before Clang 11, update LLVM+Clang:

curl --output clang.tar.xz -L https://github.com/llvm/llvm-project/releases/download/llvmorg-11.0.0/clang+llvm-11.0.0-x86_64-apple-darwin.tar.xz
mkdir clang
tar -xvJf clang.tar.xz -C clang
cd clang/clang+llvm-11.0.0-x86_64-apple-darwin
sudo cp -R * /usr/local/

Update CMake with

sudo brew upgrade cmake

or download the most recent version from cmake.org.

If the last command fails because you don’t have Homebrew on your computer, you can install it with

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

or you can follow the instructions in https://brew.sh.

Instructions: Windows/MSVC

• Make sure you have a recent version of Visual Studio
• Download Git from https://git-scm.com/download/win and install it
• Download CMake from https://cmake.org/download/ and install it

You can see the dependencies in source/CMakeLists.txt.
