PR Description: Add Automatic Linux Tauri Dependency Installation

Summary

This PR adds comprehensive Linux distribution detection and automatic installation of Tauri system dependencies during repository setup. It solves the javascriptcoregtk-4.1 dependency error that prevents make codelayer-dev from running on Linux systems, making the development setup seamless across Arch, Debian/Ubuntu, Fedora/RHEL, and openSUSE distributions.

Problem

When running make codelayer-dev on Linux systems, developers encountered a build failure:

cargo:warning=
pkg-config exited with status code 1
> PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags javascriptcoregtk-4.1

The system library `javascriptcoregtk-4.1` required by crate `javascriptcore-rs-sys` was not found.
The file `javascriptcoregtk-4.1.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.

This occurred because Tauri requires webkit2gtk and other system dependencies that aren't automatically installed. The existing setup process didn't handle Linux-specific dependencies, requiring developers to:

  1. Encounter the error
  2. Manually research the required packages for their distribution
  3. Manually install packages
  4. Retry the build

This created friction for Linux developers and made the "quick start" experience on Linux frustrating.

Solution

Enhanced the existing hack/install_platform_deps.sh script (which was previously a placeholder) to:

  1. Detect Linux Distribution: Automatically identify Arch, Debian/Ubuntu, Fedora/RHEL, openSUSE, and other distributions using /etc/os-release

  2. Install Distribution-Specific Packages: Use the appropriate package manager to install Tauri dependencies:

    • Arch/Manjaro: webkit2gtk-4.1 base-devel curl wget openssl gtk3 libappindicator-gtk3 librsvg (via pacman)
    • Debian/Ubuntu: libwebkit2gtk-4.1-dev build-essential curl wget file libssl-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev (via apt)
    • Fedora/RHEL: webkit2gtk4.1-devel openssl-devel curl wget file gcc gcc-c++ make gtk3-devel libappindicator-gtk3-devel librsvg2-devel (via dnf/yum)
    • openSUSE: webkit2gtk3-devel libopenssl-devel curl wget file gcc gcc-c++ make gtk3-devel libappindicator3-devel librsvg-devel (via zypper)
  3. Smart Installation Checks: Verify if key dependencies (like webkit2gtk-4.1) are already installed before attempting installation, avoiding unnecessary sudo prompts

  4. Helpful Error Messages: Provide clear manual installation commands if automated installation fails

  5. Integration with Setup: Modified hack/setup_repo.sh to call the platform dependencies script early in the setup process

The package lists match those used in .github/workflows/main.yml for CI builds, ensuring consistency between local and CI environments.

Changes

  • Enhanced hack/install_platform_deps.sh with comprehensive Linux support (+105 lines)

    • Added distribution detection logic
    • Added package manager detection and installation commands for 5+ distributions
    • Added pre-installation checks to avoid reinstalling existing packages
    • Added helpful error messages with manual fallback instructions
  • Modified hack/setup_repo.sh to call platform dependency installation (+4 lines)

    • Calls hack/install_platform_deps.sh before other setup steps
    • Ensures Tauri dependencies are available before building

Breaking Changes

None. This is purely additive functionality that improves the developer experience on Linux.

Migration Notes

None. Existing workflows are unaffected. Developers on Linux will automatically benefit from the improved setup process when they run make setup or make codelayer-dev (which calls daemon-dev-build, which depends on setup).

How to verify it

  • Run bash hack/install_platform_deps.sh on Arch Linux - Successfully detects distribution and confirms dependencies installed
  • Verify script syntax is valid: bash -n hack/install_platform_deps.sh - Passes
  • Verify idempotency: script doesn't attempt reinstallation when packages already exist
  • Test on fresh Arch Linux system without webkit2gtk installed (requires manual testing)
  • Test on fresh Ubuntu/Debian system (requires manual testing)
  • Test on fresh Fedora system (requires manual testing)
  • Verify make setup successfully installs dependencies on clean Linux system
  • Verify make codelayer-dev works after setup on clean Linux system

Note: Full verification requires testing on fresh Linux installations across different distributions. The script logic has been verified against GitHub Actions workflow package lists and tested on Arch Linux with pre-installed dependencies.

Changelog Entry

feat: add automatic Linux Tauri dependency installation to make setup

Additional Context

This change improves the Linux development experience significantly, bringing it in line with macOS where Tauri dependencies are typically pre-installed. It aligns with the repository's philosophy of making setup as frictionless as possible.

The implementation pattern matches the existing CI setup in .github/workflows/main.yml which already installs these dependencies for Ubuntu runners, but extends it to support local development across multiple distributions.

Testing Notes:
The script was tested on Arch Linux where webkit2gtk-4.1 was already installed, successfully detecting the existing installation and skipping reinstallation. Additional testing on clean installations and other distributions would be valuable but requires appropriate test environments.


Important

Adds automatic installation of Tauri dependencies for Linux distributions in hack/install_platform_deps.sh, enhancing setup in hack/setup_repo.sh.

  • Behavior:
    • hack/install_platform_deps.sh now detects Linux distribution and installs Tauri dependencies using the appropriate package manager (pacman, apt, dnf/yum, zypper).
    • Checks if key dependencies like webkit2gtk-4.1 are already installed to avoid unnecessary installations.
    • Provides manual installation instructions if automated installation fails.
    • hack/setup_repo.sh modified to call install_platform_deps.sh early in the setup process.
  • Misc:
    • Adds helpful error messages for unsupported distributions or missing package managers.

The dependency check for Debian/Ubuntu systems only verifies libwebkit2gtk-4.1-dev but the installation command includes many more packages. Consider checking for additional key packages or using a more comprehensive check to avoid partial installations.

The Fedora/RHEL section lacks pre-installation checks unlike the Arch and Debian sections. This will always attempt installation even if packages are already present, leading to unnecessary sudo prompts.

  • Draft comment:
    Consider adding a newline at the end of the file for POSIX compliance.
  • Reason this comment was not posted:
    Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% While POSIX compliance for newlines is a real thing, this is a markdown documentation file, not code. The lack of a trailing newline won't affect functionality. This seems like an overly pedantic comment that doesn't add meaningful value. Most modern editors handle this automatically anyway. Perhaps in some environments or tools, missing trailing newlines could cause minor issues with text processing or display. Some style guides do recommend this practice. While technically correct, this is too minor an issue to warrant a PR comment, especially for a documentation file. The benefit doesn't justify the cognitive overhead of another comment. Delete this comment as it's too minor and pedantic to be worth raising in a PR review, especially for a markdown documentation file.

    For improved robustness, consider using 'set -euo pipefail' instead of just 'set -e'.
  • Reason this comment was not posted:
    Comment was not on a location in the diff, so it can't be submitted as a review comment.
3. hack/install_platform_deps.sh:110
  • Draft comment:
    Exiting with 'exit 0' for unsupported distributions may mask missing dependencies; consider using a non-zero exit code to indicate failure.
  • Reason this comment was not posted:
    Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50% The current exit 0 is actually appropriate here. This is not a failure case - it's a known limitation where we deliberately choose to let the user handle dependencies manually. The script successfully detected this situation and provided helpful information. Throughout the rest of the script, exit 1 is used for actual failures like missing package managers or failed installations. Using exit 1 here would incorrectly indicate a failure when it's really just an unsupported case. Maybe unsupported distributions should be treated as errors since the script failed to accomplish its goal of installing dependencies? The script's goal in this case is to detect the environment and provide guidance - which it successfully does. Installation is only attempted for supported distributions. For unsupported ones, providing information and gracefully exiting is the correct behavior. The current exit 0 is the right choice. This indicates successful detection and handling of an unsupported case, rather than a failure.
4. hack/install_platform_deps.sh:94
  • Draft comment:
    Ensure that the 'webkit2gtk3-devel' package on openSUSE meets Tauri’s 4.1 requirements, as other distributions install a 4.1 variant.
  • Reason this comment was not posted:
    Comment did not seem useful. Confidence is useful = 0% <= threshold 50% This comment is related to a dependency, specifically a package version for a specific distribution. The comment is asking to ensure compatibility with a specific version requirement, which falls under the rule of not commenting on dependency changes or library versions that are not recognized. Therefore, this comment should be removed.
5. hack/install_platform_deps.sh:38
  • Draft comment:
    Consider verifying sudo privileges or checking if the user has sufficient permissions before attempting package installations.
  • Reason this comment was not posted:
    Comment did not seem useful. Confidence is useful = 20% <= threshold 50% The comment suggests verifying sudo privileges or checking user permissions before package installations. This is a general suggestion and not specific to the code changes in the PR. It doesn't provide a specific code suggestion or point out a potential issue in the code. It seems to be more of a best practice reminder, which doesn't align with the rules for useful comments.
6. hack/setup_repo.sh:46
  • Draft comment:
    The call to install platform-specific dependencies is clear and well-placed.
  • Reason this comment was not posted:
    Confidence changes required: 0% <= threshold 50% None
