# 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 (10.15 and 11). `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 |
| package manager | vcpkg, conan, choco, brew |
| cache | cppcache |
| documentation | doxygen, graphviz |
| coverage | gcovr, opencppcoverage, kcov |
| other | python, sevenzip |
`setup-cpp` automatically installs the dependencies above tools if needed for the selected tool (e.g., `python` is required for `conan`).
# Usage
## From Terminal
You should download the executable file or the js file (if Nodejs installed), and run it with the available options.
Tip: You can automate downloading using `wget`, `curl`, or other similar tools.
### Executable
Download the executable for your platform from [here](https://github.com/aminya/setup-cpp/releases/tag/v0.18.0), and run it with the available options.
An example that installs llvm, cmake, ninja, ccache, and vcpkg:
```ps1
# windows example (open shell as admin)
curl.exe -LJO "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp_windows.exe"
.\setup_cpp_windows --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
RefreshEnv.cmd # activate cpp environment variables
```
```ps1
# linux example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp_linux"
chmod +x setup_cpp_linux
sudo ./setup_cpp_linux --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc # activate cpp environment variables
```
```ps1
# mac example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp_mac"
chmod +x setup_cpp_mac
sudo ./setup_cpp_mac --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
source ~/.cpprc # activate cpp environment variables
```
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, you will not need `sudo` if you are already a root user (e.g., in a GitLab runner or Docker).
### With Nodejs
Download the `setup_cpp.js` file form [here](https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp.js), and run it with the available options.
On Windows:
Open the shell as admin, download via `curl`, then install
```ps1
# open shell as admin
curl.exe -LJO "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp.js"
node ./setup_cpp.js --compiler llvm --cmake true --ninja true --ccache true --vcpkg true
RefreshEnv.cmd # activate cpp environment variables
```
On Linux or Mac:
```ps1
wget "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp.js"
sudo node ./setup_cpp.js --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-20.04
- macos-11
compiler:
- llvm
- gcc
# you can specify the version after `-` like `llvm-13.0.0`.
include:
- os: "windows-2022"
compiler: "msvc"
steps:
- uses: actions/checkout@v2
- name: Cache
uses: actions/cache@v2
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 base
# add setup_cpp
WORKDIR "/"
RUN apt-get update -qq
RUN apt-get install -y --no-install-recommends wget
RUN wget --no-verbose "https://github.com/aminya/setup-cpp/releases/download/v0.18.0/setup_cpp_linux"
RUN chmod +x ./setup_cpp_linux
# install llvm, cmake, ninja, and ccache
RUN ./setup_cpp_linux --compiler llvm --cmake true --ninja true --ccache true --vcpkg true --make true
CMD source ~/.cpprc
ENTRYPOINT [ "/bin/bash" ]
#### Building
FROM base AS builder
ADD ./dev/cpp_vcpkg_project /home/app
WORKDIR /home/app
RUN bash -c 'source ~/.cpprc \
&& make build'
### Running environment
# use a distroless image or ubuntu:22.04 if you wish
FROM gcr.io/distroless/cc
# 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:
```ps1
git clone --recurse-submodules https://github.com/aminya/setup-cpp
cd ./setup-cpp
docker build -f ./dev/docker/ubuntu.dockerfile -t setup_cpp .
```
Where you should use the path to the dockerfile after `-f`.
After build, run the following to start an interactive shell in your container
```ps1
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: ${{ matrix.os }}
strategy:
matrix:
os:
- ubuntu-20.04
steps:
- uses: actions/checkout@v2
- name: Build
id: docker_build
run: |
docker build -f ./dev/docker/debian.dockerfile -t setup_cpp .
env:
ACTIONS_ALLOW_UNSECURE_COMMANDS: true
```
## Inside GitLab pipelines
The following gives an example for setting up a C++ environment inside GitLab pipelines.
.gitlab-ci.yaml
```yaml
image: ubuntu:22.04
stages:
- test
.setup_linux: &setup_linux |
DEBIAN_FRONTEND=noninteractive
# set time-zone
TZ=Canada/Pacific
ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# for downloading
