Manual Installation

To build the theme the following packages are required

• autoconf
• automake
• sassc
• pkg-config or pkgconfig for Fedora
• libgtk-3-dev for Debian based distros or gtk3-devel for RPM based distros
• git to clone the source directory
• optipng
• inkscape

Note: For distributions which don't ship separate development packages, just the GTK 3 package is needed instead of the -dev packages.

For the theme to function properly, install the following

• GNOME Shell 3.18 - 3.26, GTK 3.18 - 3.22
• The gnome-themes-extra package
• The murrine engine. This has different names depending on the distro.
  • gtk-engine-murrine (Arch Linux)
  • gtk2-engines-murrine (Debian, Ubuntu, elementary OS)
  • gtk-murrine-engine (Fedora)
  • gtk2-engine-murrine (openSUSE)
  • gtk-engines-murrine (Gentoo)

Install the theme with the following commands

1. Get the source

Clone the git repository with

git clone https://github.com/NicoHood/arc-theme --depth 1 && cd arc-theme

2. Build and install the theme

./autogen.sh --prefix=/usr
sudo make install

Other options to pass to autogen.sh are

--disable-transparency     disable transparency in the GTK3 theme
--disable-light            disable Arc Light support
--disable-darker           disable Arc Darker support
--disable-dark             disable Arc Dark support
--disable-cinnamon         disable Cinnamon support
--disable-gnome-shell      disable GNOME Shell support
--disable-gtk2             disable GTK2 support
--disable-gtk3             disable GTK3 support
--disable-metacity         disable Metacity support
--disable-unity            disable Unity support
--disable-xfwm             disable XFWM support
--disable-plank            disable Plank theme support
--disable-openbox          disable Openbox support

--with-gnome=<version>     build the theme for a specific GNOME version (3.18, 3.20, 3.22)
                           Note 1: Normally the correct version is detected automatically and this
                           option should not be needed.
                           Note 2: For GNOME 3.24 and 3.26, use --with-gnome=3.22
                           (this works for now, the build system will be improved in the future)
--with-custom=<script>     run the executable script file in the custom subfolder

After the installation is complete the theme can be activated with gnome-tweak-tool or a similar program by selecting Arc, Arc-Darker or Arc-Dark as Window/GTK+ theme and Arc or Arc-Dark as GNOME Shell/Cinnamon theme.

If the --disable-transparency option was used, the theme will be installed as Arc-solid, Arc-Darker-solid and Arc-Dark-solid.
