Installing hydro on archlinux

Installing Hydro with AUR packages

The other possibility (just like for Groovy) is to use AUR packages. If you use yaourt (or packer), you can check the available ROS Hydro packages by typing:

yaourt ros-hydro

To avoid confirmation for all the packages, you can add the --no-confirm option:

yaourt --noconfirm ros-hydro

Then simply pick the packages you want. If we take your example, this would be:

yaourt --noconfirm ros-hydro-ros-comm

Note that packages are currently being added. Even though most official packages have been added, some may still be missing.

Adding new AUR packages

If you want to help packaging for Arch Linux, you can use import_catkin_packages.py available in ros-build-tools. You can fork arch-ros-stacks and contribute by doing this:

# Go to ros-build-tools upstream scripts
cd /path/to/arch-ros-stacks/dependencies/ros-build-tools

# List available packages
python2 import_catkin_packages.py --distro=hydro --list

# Generate PKGBUILD for a given package
python2 import_catkin_packages.py --distro=hydro --output-directory=/path/to/arch-ros-stacks/hydro package_name

# Go to newly created package directory
cd ../../hydro/package_name

# Build, install, add to Git and create AUR source tarball
# You may need to apply some patches in the PKGBUILD (e.g. for Ogre 1.8)
makepkg -if && git add PKGBUILD && makepkg --source

After that, you can upload the new package's *.src.tar.gz to AUR, commit and make a pull request on GitHub. Thus, other Arch Linux users will be able to install your package by simply typing:

yaourt ros-hydro-package-name

Note that you can also create PKGBUILDs manually (just copy another package's PKGBUILD and adapt it), but the automatic process is probably the safest option, since it gets the latest release version, the adequate dependencies, the short description etc.
