Alternatively, you may build the toolchain from scratch using the buildscripts
Install the toolchain to a directory of your choice
We recommend /usr/local/vitasdk for Linux and /opt/vitasdk for OSX
On Windows, it is recommended you install MSYS2 and make (pacman -S make) in order to use Makefiles.
Setup the $VITASDK path variable to point to where the toolchain is installed
On Linux/OSX you can add export VITASDK=/path/to/toolchain to your Bash profile
Building
You can find various sample code here. Build them and play around with the code to familiarize yourself with the environment. You can also look at the showcase to see some more advanced code. Unfortunately, there currently does not exist comprehensive documentation for the unoffical SDK. If you have the time, please help us with that!
Edit: I copied this directly from the Henkaku website, also I don't know what Linux derivative(s) this can be installed on since not every derivative is created the same way.
