Building for Vita

Prerequisites

Note: In order to build Julius for the PS Vita, you'll need to install docker and git.

Instead of docker you can directly use VitaSDK, but its installation and configuration are beyond the scope of this page.

1. Installing git:

   a. For a Debian-based Linux distribution, open a Terminal window and type sudo apt install git

   b. For Mac OS, follow installing the command line developer tools in the Mac OS section

   c. For Windows, follow installing Git for Windows in the Windows section

2. To install docker, check installing docker.

Building Julius

1. Open a Terminal window.

2. Navigate to the directory where you want the repository folder to be installed. As an example, we're using the home folder:

    $ cd ~
   

3. Clone the Julius github repository to your computer:

    $ git clone https://github.com/bvschaik/julius.git
   

4. Move to the new julius directory:

    $ cd julius
   

   Optional: If you have already downloaded the Julius repository and only wish to update it (in order to build a newer version), instead of the previous three steps, do the following in a terminal window:

   a. Move to the julius directory where the repository was installed.

   b. Type:

        $ git pull origin master
   

   c. Delete the build directory:

        $ rm -rf build
   

   d. Proceed to step 5.

5. Obtain the proper docker image for Vita development.

    $ docker run -d --name vitasdk --workdir /build/git -v "${PWD}:/build/git" gnuton/vitasdk-docker:20210217 tail -f /dev/null
   

6. Use docker to create the build directory and configure cmake:

    $ docker exec vitasdk /bin/bash -c "mkdir build && cd build && cmake -DCMAKE_BUILD_TYPE=Release -DTARGET_PLATFORM=vita .."
   

7. Build Julius using docker:

    $ docker exec vitasdk /bin/bash -c "cd build && make"
   

Success! Julius should have been built without any errors. There should be a file called julius.vpk in the build folder.
