Installation on MacOS

Dependencies

The PSPDEV toolchain requires a couple of dependencies to be installed before use. Installing them can be done using brew.

Once brew is installed, run the following command from a terminal to install the dependencies:

brew install cmake pkgconf gnu-sed bash openssl libtool libmpc libarchive gettext texinfo bison flex isl gsl gmp mpfr

Installing the PSPDEV toolchain itself can be done with the following steps:

Download the latest version of the toolchain for your system here:
- arm64 for M1 or newer CPUs.
- x86_64 for Intel CPUs.
Extract the downloaded archive into your home directory, resulting in /home/YOURUSERNAME/pspdev being created.
To make the toolchain usable, some environment variables need to be set. The first step in doing so it to open the ~/.zprofile file with the pico text editor using the following command from a terminal:
```
 pico ~/.zprofile
```

Add the following lines at the bottom of the file in the text editor:

 export PSPDEV="$HOME/pspdev"
 export PATH="$PATH:$PSPDEV/bin"

Now save and exit by pressing Ctrl+X, then Y and then enter/return.
Run the following command to remove the gatekeeper quarantine, allowing executables to be run:
```
 xattr -rd com.apple.quarantine $HOME/pspdev
```
Close the current terminal and open a new one.
From the new terminal, run the following command to confirm everything is set up correctly:
```
 psp-config --pspdev-path
```

That’s it, now the PSPDEV toolchain can be used to build PSP software. Check out the Basic Programs page to for examples on what you can do with it.
