AwesomeCppTemplate

This project is in its infancy and I plan to continue to improve. It is designed to use C++17. I hope people be able to create the desired C++ project files layout fast and simply. and also I'm very welcome to contributions.

My goal is to make C++ version of Python cookiecutter. then people can create C++ project files layout very simply by a single line of command. I hope some contributors to participate.

Possibly, the project name "AwesomeCppTemplate" make people confused with C++ Template Programming but it's not :). My first choice for the name sucks. My bad... "C++FilesLayout" is more appropriate I think.

There a lot of useful opinions that I have to look at in Reddit thread for this project. The link is here.

Suggestion of C++ programming environment

I suggest using as much cross-platform open-source software as possible:

  • build system generator: CMake
  • build system: Ninja
  • compiler: clang++
  • IDE:
    • Visual Studio Code
    • ⁠Qt Creator
  • static code analyzers:
    • clang-tidy
    • Cppcheck
    • Clazy
  • source code formatter: clang-format
  • documentation generator: Doxygen
  • package manager:
    • ⁠Conan
    • ⁠vcpkg
  • libraries:
    • Standard Library
    • Boost
    • string formatting: fmt
    • logging: spdlog
    • automated tests: Google Test / Google Mock
    • GUI: Qt

Prerequisites

$ sudo apt update && sudo apt upgrade -y
  1. Install Clang and LLVM (7 release)

Update apt packages list:

$ sudo apt update

To retrieve the archive signature:

$ wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add -
# Fingerprint: 6084 F3CF 814B 57C1 CF12 EFD5 15CF 4D18 AF4F 7421

To install just clang, lld and lldb:

$ sudo apt install clang-7 lldb-7 lld-7

To install all key packages:

# LLVM
$ sudo apt install libllvm-7-ocaml-dev libllvm7 llvm-7 llvm-7-dev llvm-7-doc llvm-7-examples llvm-7-runtime

# Clang and co
$ sudo apt install clang-7 clang-tools-7 clang-7-doc libclang-common-7-dev libclang-7-dev libclang1-7 clang-format-7 python-clang-7

# libfuzzer
$ sudo apt install libfuzzer-7-dev

# lldb
$ sudo apt install lldb-7

# lld (linker)
$ sudo apt install lld-7

# libc++
$ sudo apt install libc++-7-dev libc++abi-7-dev

# OpenMP
$ sudo apt install libomp-7-dev

Finally, link each clang-7 and clang++-7 to clang and clang++.

$ sudo ln -s /usr/bin/clang-7 /usr/bin/clang
$ sudo ln -s /usr/bin/clang++-7 /usr/bin/clang++

Check if all the packages are installed fine.

$ clang++ --version
clang version 7.0.0-3~ubuntu0.18.04.1 (tags/RELEASE_700/final)

Thread model: posix
InstalledDir: /usr/bin
  1. Install CMake
$ sudo apt install cmake
  1. Install Conan
$ sudo apt install python3
$ sudo apt install python3-pip
$ sudo pip3 install --upgrade pip
$ pip install conan

Then change default profile of conan:

$ conan profile new default --detect
$ conan profile update settings.compiler=clang++
$ conan profile update settings.compiler.version=7.0
$ conan profile update settings.compiler.libcxx=libc++
  1. Install Ninja
$ sudo apt install ninja-build

Build examples

$ mkdir build && cd build
$ conan install ..
$ export CC=clang
$ export CXX=clang++
$ cmake .. -G Ninja
$ cmake --build .

Try running the example binary!

$ ./bin/md5
