Using devkitPro on a RPM-based distro

Since devkitPro packages are distributed as pacman packages, you need pacman to install them. But some RPM-based distros do not have pacman. With a bit of work, you can get devkitPro's custom pacman (dkp-pacman) installed, if you follow the steps below.

Setup

1. Download the rpm package from the releases page.

2. Install the rpm:

   sudo rpm --install devkitpro-pacman-*.x86_64.rpm
   

3. Now set up dkp-pacman according to devkitPro's instructions:

   sudo dkp-pacman-key --init
   sudo dkp-pacman-key --recv  BC26F752D25B92CE272E0F44F7FD5492264BB9D0 --keyserver keyserver.ubuntu.com
   sudo dkp-pacman-key --lsign BC26F752D25B92CE272E0F44F7FD5492264BB9D0
   sudo dkp-pacman -Syu
   

   This last command will install an update for dkp-pacman, overriding the files installed by the RPM package.

Now you're ready to start installing the devkitPro packages you want.

Preparing your environment

Most homebrew build scripts expect the environment variable DEVKITPRO to be pointing to the root of devkitPro (/opt/devkitpro); similarly for DEVKITARM and DEVKITPPC. This is my preferred way to set it up, on a distro that uses systemd:

1. Create the file ~/.config/environment.d/devkitpro.conf with these lines:

   DEVKITPRO=/opt/devkitpro
   DEVKITARM=${DEVKITPRO}/devkitARM
   DEVKITPPC=${DEVKITPRO}/devkitPPC
   

2. Log out and back in again. You can check that the variable was defined properly by running this in a terminal:

   printenv DEVKITPRO
   

3. (Optional) If you want to bring the devkitPro tools into your PATH during a terminal session, you can install the dkp-toolchain-vars package, which will install various shell scripts into /opt/devkitpro that can be sourced.

   For instance, to set up a Wii U environment, you can do:

   source $DEVKITPRO/wiiuvars.sh
   

   Note that these will override variables like CC, CXX, CPPFLAGS, etc, making it very difficult to use your native compiler.

   For maximum convenience, you can add these aliases to your ~/.bash_aliases:

   alias 3ds-env='source $DEVKITPRO/3dsvars.sh'
   alias cube-env='source $DEVKITPRO/cubevars.sh'
   alias nds-env='source $DEVKITPRO/ndsvars.sh'
   alias switch-env='source $DEVKITPRO/switchvars.sh'
   alias wii-env='source $DEVKITPRO/wiivars.sh'
   alias wiiu-env='source $DEVKITPRO/wiiuvars.sh'
   

   Now you can just run wiiu-env to activate the Wii U environment, or similarly for the other consoles.
