# setup-cpp
Install all the tools required for building and testing C++/C projects.
![Build Status (Github Actions)](https://github.com/aminya/setup-cpp/workflows/CI/badge.svg)
Setting up a **cross-platform** environment for building and testing C++/C projects is a bit tricky. Each platform has its own compilers, and each of them requires a different installation procedure. This package aims to fix this issue.
`setup-cpp` can be used locally from terminal, from CI services like GitHub Actions and GitLab Pipelines, and inside containers like Docker.
`setup-cpp` is supported on many platforms. It is continuously tested on several configurations including Windows (11, 10, 2022, 2019), Linux (Ubuntu 22.04, Ubuntu 20.04, Fedora, ArchLinux), and macOS (12, 11, 10.15). `setup-cpp` is backed by unit tests for each tool and integration tests for compiling cpp projects.
## Features
`setup-cpp` is **modular** and you can choose to install any of these tools:
| category | tools |
| --------------------- | ------------------------------------------------------------ |
| compiler and analyzer | llvm, gcc, msvc, vcvarsall, cppcheck, clangtidy, clangformat |
| build system | cmake, ninja, meson, make, task, bazel |
| package manager | vcpkg, conan, choco, brew, nala |
| cache | cppcache, sccache |
| documentation | doxygen, graphviz |
| coverage | gcovr, opencppcoverage, kcov |
| other | python, powershell, sevenzip |
`setup-cpp` automatically handles the dependencies of the selected tool (e.g., `python` is required for `conan`).
## Usage
### From Terminal
#### With npm and Nodejs
Run `setup-cpp` with the available options.
```shell
# Windows example (open PowerShell as admin)
npx setup-cpp --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
RefreshEnv.cmd # activate the environment
```
```shell
# Linux/Macos example
sudo npx setup-cpp --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc
```
NOTE: In the `compiler` entry, you can specify the version after `-` like `llvm-11.0.0`. For the tools, you can pass a specific version instead of `true` that chooses the default version
NOTE: On Unix systems, when `setup-cpp` is used locally or in other CI services like GitLab, the environment variables are added to `~/.cpprc`. You should run `source ~/.cpprc` to immediately activate the environment variables. This file is automatically sourced in the next shell restart from `~/.bashrc` or `~/.profile` if `SOURCE_CPPRC` is not set to `0`. To deactivate `.cpprc` in the next shell restart, rename/remove `~/.cpprc`.
NOTE: On Unix systems, if you are already a root user (e.g., in a GitLab runner or Docker), you will not need to use `sudo`.
#### With executable
Download the executable for your platform from [here](https://github.com/aminya/setup-cpp/releases/tag/v0.35.6), and run it with the available options. You can also automate downloading using `wget`, `curl`, or other similar tools.
An example that installs llvm, cmake, ninja, ccache, and vcpkg:
```shell
# windows example (open PowerShell as admin)
curl -LJO "https://github.com/aminya/setup-cpp/releases/download/v0.35.6/setup-cpp-x64-windows.exe"
./setup-cpp-x64-windows --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
RefreshEnv.cmd # activate cpp environment variables
```
```shell
# linux example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.35.6/setup-cpp-x64-linux"
chmod +x ./setup-cpp-x64-linux
sudo ./setup-cpp-x64-linux --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc # activate cpp environment variables
```
```shell
# macos example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.35.6/setup-cpp-x64-macos"
chmod +x ./setup-cpp-x64-macos
sudo ./setup-cpp-x64-macos --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc # activate cpp environment variables
```
### Inside GitHub Actions
Here is a complete cross-platform example that tests llvm, gcc, and msvc. It also uses cmake, ninja, vcpkg, and cppcheck.
`.github/workflows/ci.yml`:
```yaml
name: ci
on:
pull_request:
push:
branches:
- main
- master
jobs:
Test:
runs-on: ${{ matrix.os }}
strategy:
fail-fast: false
matrix:
os:
- windows-2022
- ubuntu-22.04
- macos-12
compiler:
- llvm
- gcc
# you can specify the version after `-` like `llvm-13.0.0`.
include:
- os: "windows-2022"
compiler: "msvc"
steps:
- uses: actions/checkout@v3
- name: Cache
uses: actions/cache@v3
with:
path: |
~/vcpkg
./build/vcpkg_installed
${{ env.HOME }}/.cache/vcpkg/archives
${{ env.XDG_CACHE_HOME }}/vcpkg/archives
${{ env.LOCALAPPDATA }}\vcpkg\archives
${{ env.APPDATA }}\vcpkg\archives
key: ${{ runner.os }}-${{ matrix.compiler }}-${{ env.BUILD_TYPE }}-${{ hashFiles('**/CMakeLists.txt') }}-${{ hashFiles('./vcpkg.json')}}
restore-keys: |
${{ runner.os }}-${{ env.BUILD_TYPE }}-
- name: Setup Cpp
uses: aminya/setup-cpp@v1
with:
compiler: ${{ matrix.compiler }}
vcvarsall: ${{ contains(matrix.os, 'windows') }}
cmake: true
ninja: true
vcpkg: true
cppcheck: true
clangtidy: true # instead of `true`, which chooses the default version, you can pass a specific version.
# ...
```
### Inside Docker
Here is an example for using setup-cpp to make a builder image that has the Cpp tools you need.
```dockerfile
#### Base Image
FROM ubuntu:22.04 as setup-cpp-ubuntu
RUN apt-get update -qq && \
# install nodejs
apt-get install -y --no-install-recommends nodejs npm && \
# install setup-cpp
npm install -g setup-cpp@v0.35.6 && \
# install the compiler and tools
setup-cpp \
--nala true \
--compiler llvm \
--cmake true \
--ninja true \
--task true \
--vcpkg true \
--python true \
--make true \
--cppcheck true \
--gcovr true \
--doxygen true \
--ccache true && \
# cleanup
nala autoremove -y && \
nala autopurge -y && \
apt-get clean && \
nala clean --lists && \
rm -rf /var/lib/apt/lists/* && \
rm -rf /tmp/*
ENTRYPOINT ["/bin/bash"]
#### Building (example)
FROM setup-cpp-ubuntu AS builder
COPY ./dev/cpp_vcpkg_project /home/app
WORKDIR /home/app
RUN bash -c 'source ~/.cpprc \
&& task build'
#### Running environment
# use a fresh image as the runner
FROM ubuntu:22.04 as runner
# copy the built binaries and their runtime dependencies
COPY --from=builder /home/app/build/my_exe/Release/ /home/app/
WORKDIR /home/app/
ENTRYPOINT ["./my_exe"]
```
See [this folder](https://github.com/aminya/setup-cpp/tree/master/dev/docker), for some dockerfile examples.
If you want to build the ones included, then run:
```shell
git clone --recurse-submodules https://github.com/aminya/setup-cpp
cd ./setup-cpp
docker build -f ./dev/docker/setup-cpp-ubuntu.dockerfile -t setup-cpp-ubuntu .
```
Where you should use the path to the dockerfile after `-f`.
After build, run the following to start an interactive shell in your container
```shell
docker run -it setup-cpp
```
### Inside Docker inside GitHub Actions
You can use the docker file discussed in the previous section inside GitHub Actions like the following:
```yaml
jobs:
Docker:
runs-on: ${{ matrix.os }}
strategy:
matrix:
os:
- ubuntu-22.04
steps:
- uses: actions/checkout@v3
- name: Build
id: docker_build
run: |
docker build -f ./dev/docker/ubuntu.dockerfile -t setup-cpp .
```
### Inside GitLab pipelines
The following gives an example for setting up a C++ environment inside GitLab pipelines.
.gitlab-ci.yaml
```yaml
image: ubuntu:22.04
stages:
- test
.setup_linux: &setup_linux |
DEBIAN_FRONTEND=noninteractive
# set time-zone
TZ=Canada/Pacific
ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# for downloading
apt-get update -qq
apt-get install -y --no-install-recommends curl gnupg ca-certificates
.setup-cpp: &setup-cpp |
# install nodejs
apt-get install -y --no-install-recommends nodejs npm
# install setup-cpp
npm install -g setup-cpp@v0.35.6
# install the compiler and tools
./setup-cpp-x64-linux --compiler $compiler --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc
.test: &test |
# Build and Test
# ...
test_linux_llvm:
stage: test
variables:
compiler: llvm
script:
- *setup_linux
- *setup-cpp
- *test
test_linux_gcc:
stage: test
variables:
compiler: gcc
script:
