# setup-cpp
|
|
|
|
Install all the tools required for building and testing C++/C projects.
|
|
|
|
|
|
|
|
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.
|
|
|
|
This package is designed to be **modular** and as **minimal** as possible. This will allow you to install the tools you want. It is continuously tested on Windows, Linux, and macOS.
|
|
|
|
The package can be used locally or from CI services like GitHub Actions.
|
|
|
|

# 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/v0.13.2), 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 -LJO "https://github.com/aminya/setup-cpp/releases/download/v0.13.2/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/v0.13.2/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/v0.13.2/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/v0.13.2/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 -LJO "https://github.com/aminya/setup-cpp/releases/download/v0.13.2/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/v0.13.2/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
|

|
|

|
|
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:devel 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/v0.13.2/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:devel 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:devel
|
|
|
|

|
|
- 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
|
