ps2dev / ps2gdb

PS2 GDB stub

ps2dev

Main PS2 Repo for building the whole PS2 Development environment in your local machine.

This program will automatically build and install the whole compiler and other tools used in the creation of homebrew software for the Sony PlayStation® 2 videogame system.

What these scripts do

These scripts download (git clone) and install:

• ps2toolchain
• ps2sdk
• ps2sdk-ports
• gsKit
• ps2-packer
• ps2client

Requirements

1. Install gcc/clang, make, cmake, patch, git, texinfo, flex, bison, gettext, wget, gsl, gmp, zlib, mpfr and mpc if you don't have those packages.

• Ubuntu

sudo apt -y install gcc g++ make cmake patch git texinfo flex bison gettext libgsl-dev libgmp3-dev libmpfr-dev libmpc-dev zlib1g-dev

• Fedora/CentOS

sudo dnf -y install gcc make cmake patch git texinfo flex bison gettext gmp-devel mpfr-devel libmpc-devel zlib-devel

• Alpine

apk add build-base cmake git texinfo flex bison gettext gmp-dev mpfr-dev mpc1-dev zlib-dev

2. Optional. If you are upgrading from the previous version of the PS2DEV environment, it is highly recommended to remove the content of the PS2DEV folder before upgrade. This is a necessary step after the major toolchain upgrade.

sudo rm -rf $PS2DEV

3. Ensure that you have enough permissions for managing PS2DEV location (which defaults to /usr/local/ps2dev, but you can use a different path). PS2DEV location MUST NOT have spaces or special characters in its path! PS2DEV should be an absolute path. On Unix systems, if the command mkdir -p $PS2DEV fails for you, you can set access for the current user by running commands:

export PS2DEV=/usr/local/ps2dev
sudo mkdir -p $PS2DEV
sudo chown -R $USER: $PS2DEV

4. Add this to your login script (example: ~/.bash_profile) Note: Ensure that you have full access to the PS2DEV path. You can change the PS2DEV path with the following requirements: only use absolute paths, don't use spaces, only use Latin characters.

export PS2DEV=/usr/local/ps2dev
export PS2SDK=$PS2DEV/ps2sdk
export GSKIT=$PS2DEV/gsKit
export PATH=$PATH:$PS2DEV/bin:$PS2DEV/ee/bin:$PS2DEV/iop/bin:$PS2DEV/dvp/bin:$PS2SDK/bin

5. Run build-all.sh

./build-all.sh

Docker generation

This repo also uses CI/CD to create a docker image called ps2dev/ps2dev:latest per change. This is useful if you're a developer that wants to create/port an application to the PS2. You can compile your project using this docker image.

Extra steps

If you want, you can JUST install the extra dependencies ps2client and ps2-packer. To achieve this, execute the following:

./build-extra.sh

macOS

If you download the pre-built macOS binaries and get a security error such as "ps2client" cannot be opened because the developer cannot be verified., you can remove the quarantine attribute by running:

xattr -dr com.apple.quarantine path/to/prebuilt/ps2toolchain

ps2gdb's Issues

How to use it?

Hello,
Not sure if this should be an issue but I have been giving a try and reading into the internet but I didn't find a way to make it work.
Basically I would like to be able to debug our PS2 elf applications. The main functionality that I see as a must-have to have breakpoints and a way to inspect the value of variables.

Do we have more information about how to use it? In this case, should we improve our Readme?

Pinging @sp193 because most probably he is the one that knows more about this.

Thanks

Regarding gdb

Hello, apparently somewhere down the line GDB made a breaking change to their remote protocol.
I've spend countless hours try to compile older gccs, older gdbs etc with no success.
Do you have any ideas on what I can do?
