C++23 Project with Xmake, GTest, and CI/CD

This repository provides a simple setup for a C++23 project using Xmake as the build system, GTest for unit testing, and CI/CD workflows for both Ubuntu and Windows (x64 and x86).

Note: Please be aware that import std; currently only works for the Windows MSVC compiler and not for GCC. Modules are still not fully supported in any compiler. For example, std::print (import <print>) doesn't work in GCC-13.

Enabling GitHub Workflow to Automatically Create Releases

To allow GitHub Actions to create releases automatically, you need to grant the necessary permissions. Follow these steps:

Go to your GitHub project's Settings page. Navigate to the Actions tab. Under the Workflow permissions section, select Read and write permissions. If you don't enable these permissions, the Release step of the workflows will fail, and the releases won't be created automatically.

Project Structure

The project structure is as follows:

.
├── .github
│   └── workflows
│       ├── greetings.yml
│       ├── linux.yml
│       └── windows.yml
├── src
│   ├── hello.cppm
│   └── main.cppm
├── tests
│   ├── test_gmock.cpp
│   └── test_gtest.cpp
└── xmake.lua
  • .github/workflows/: Directory containing the CI/CD workflow files.
    • greetings.yml: Workflow file for greeting users on their first issue or pull request.
    • linux.yml: Workflow file for building and releasing the project on Linux (Ubuntu).
    • windows.yml: Workflow file for building and releasing the project on Windows.
  • src/: Directory containing the source files of the project.
  • tests/: Directory containing the test files using GTest and GMock.
  • xmake.lua: The Xmake configuration file.

Prerequisites

Before building and running the project, ensure that you have the following dependencies installed:

  • Xmake: Installation Guide
  • C++23 compiler (e.g., GCC, Clang, or MSVC). Currently I could not get it working with Clang and GCC does not have as good module support as MSVC.

Building the Project

To build the project, run the following command in the project root directory:

xmake

This command will compile the source files and generate the executable.

You can also use xmake config (or xmake f) to configure the project. For example, to set the project to compile as 32-bit, use the following command:

xmake f -a x86

This will configure the project to compile as 32-bit the next time you run xmake or xmake build.

To clean the project and remove the build files, use the following command:

xmake clean

Running the Tests

To run the tests, use the following command: xmake test

This command will execute the test files and display the test results.

CI/CD Workflows

The repository includes several CI/CD workflow files located in the .github/workflows/ directory:

  1. linux_cd.yml: Builds the project on Linux (Ubuntu) for x86_64 and x86 architectures, creates a release tag, generates a changelog, and uploads the executable as release assets.

  2. windows_cd.yml: Builds the project on Windows for x64 and x86 architectures, creates a release tag, generates a changelog, and uploads the executable as release assets.

  3. greetings.yml: Greets users on their first issue or pull request.

These workflows automate the build, testing, and release processes for the project.

Customization

This repository serves as a template and can be customized to suit your project's specific needs. Feel free to modify the project structure, add or remove files, and adjust the Xmake configuration and CI/CD workflows according to your requirements.
