На курсах backend по C++

Что делать после установки Ubuntu 18.04

sudo apt update
sudo apt -y install git
скачать vs code https://code.visualstudio.com/docs/?dv=linux64_deb
Установить расширения (extensions)
Python 2018.10.1
C/C++ 0.20.1

Перезапустить vs code

sudo apt install -y clang-6.0
sudo ln -s /usr/bin/clang++-6.0 /usr/bin/clang++
sudo ln -s /usr/bin/clang-6.0 /usr/bin/clang

sudo apt install -y make
sudo apt install -y cmake
sudo apt install -y python3-pip
sudo pip3 install conan

Прописать в файл ~/.conan/profiles/default

[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=clang
compiler.version=6.0
compiler.libcxx=libc++
build_type=Release
[options]
[build_requires]
[env]
CC=clang
CXX=clang++

Возможно, для сборки потребуется доустановить пакеты libc++-dev и libc++abi-dev.

Если cmake валится

cmake ..

-- The CXX compiler identification is GNU 7.3.0

  Incorrect 'clang', is not the one detected by CMake: 'GNU'

See also "/home/user/c++/meeting_backend/build/CMakeFiles/CMakeOutput.log".

То следует выполнить команды:

export CXX=clang++
export CC=clang

И добавить в файл используемой оболочки, например ~/.bashrc или ~/.zshrc

VS Code include path problem

В секцию includePath файла .vscode/c_cpp_properties.json добавить ~/.conan/data/**.

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "~/.conan/data/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c11",
            "cppStandard": "c++17",

        }
    ],

}
