Configure Qt Installer Framework (IFW) for cross-platform installers. This skill generates installer configurations with component management, online updates, maintenance tool, and custom branding.

Capabilities

• Generate installer configuration files
• Set up component structure with dependencies
• Configure online repository for updates
• Customize installer UI and branding
• Set up maintenance tool configuration
• Configure uninstaller behavior
• Generate component scripts
• Set up platform-specific settings

Build Commands

# Build offline installer
binarycreator -c config/config.xml -p packages MyAppInstaller

# Build online installer (small, downloads components)
binarycreator -c config/config.xml -p packages -n MyAppOnlineInstaller

# Create/update repository
repogen -p packages repository

# Update existing repository
repogen --update-new-components -p packages repository

Online Update Repository

# Initial repository creation
repogen -p packages output/repository

# Upload to server
rsync -avz output/repository/ user@server:/var/www/updates/

# Update with new version
repogen --update-new-components -p packages output/repository

Best Practices

1. Version components independently: Allow granular updates
2. Use online repository: Enable auto-updates
3. Customize UI: Match application branding
4. Test on all platforms: Verify installer behavior
5. Sign installers: Code sign for trust
6. Include maintenance tool: Allow updates/uninstall
