wut
Let's try make a Wii U Toolchain / SDK for creating rpx/rpl.
Licensed under the terms of the GNU General Public License, version 2 or later (GPLv2+).
Install
Grab the latest release extract to a folder, then export that folder as WUT_ROOT.
For example:
wget https://github.com/decaf-emu/wut/releases/download/1.0.0-alpha/wut.linux64.7z
mkdir wut && cd wut
7z x ../wut.linux64.7z
export WUT_ROOT=$PWD
Usage
See samples for examples of how to use wut.
The share/wut.cmake file provides several helpers for your build:
wut_create_rpx(target.rpx executable)
- Will create an .rpx file from your CMake target generated byadd_executable
wut_enable_newlib(target)
- Links against the wut implementation of newlib, this is useful for using any function from the C standard librarywut_enable_stdcpp(target)
- Links against the wut implementation of stdcpp, this is useful for using any function from the C++ standard library. This will call wut_enable_newlib if you have not already done so.wut_default_malloc(target)
- By default newlib will allocate 90% of the default heap for use with sbrk & malloc, if this is unacceptable to you then you should use this as it replaces the newlib malloc functions which ones which redirect to the CafeOS default heap functions such as MEMAllocFromDefaultHeap.wut_enable_devoptab_sd(target)
- This links in wutdevoptab_sd which is useful for using the libc file functions with paths such asfopen("sd:/file.txt", "r")
to read files from the sd card
A minimal CMakeLists.txt file for a C++ project might look like:
cmake_minimum_required(VERSION 3.2)
project(helloworld_cpp CXX)
include("${WUT_ROOT}/share/wut.cmake" REQUIRED)
add_executable(helloworld_cpp
main.cpp)
wut_enable_stdcpp(helloworld_cpp)
wut_create_rpx(helloworld_cpp.rpx helloworld_cpp)
Which you would compile with
export DEVKITPPC=/opt/devkitpro/devkitPPC
export WUT_ROOT=<path/to/install>
mkdir build && cd build
cmake -DCMAKE_TOOLCHAIN_FILE=$WUT_ROOT/share/wut.toolchain.cmake ../
make
Building
Requires:
- A modern compiler with C++14/17 support
- CMake
- zlib
- devkitPPC r31+
Building on Windows
Use WSL and then follow the Linux instructions.
For example, if you installed Ubuntu 18.04 then you might setup your environment like:
sudo apt install cmake zlib1g-dev gcc g++ build-essentials
wget https://github.com/devkitPro/pacman/releases/download/devkitpro-pacman-1.0.1/devkitpro-pacman.deb
sudo dpkg -i devkitpro-pacman.deb
sudo ln -s /proc/mounts /etc/mtab
sudo dkp-pacman -S devkitPPC wiiload
Building on Linux / MacOS
export DEVKITPPC=/opt/devkitpro/devkitPPC
git clone --recursive https://github.com/decaf-emu/wut.git
cd wut
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=<path/to/install> ../
make install
export WUT_ROOT=<path/to/install>
Then for any wut project you want to build you must use the wut.toolchain.cmake script:
cd ../samples/helloworld
mkdir build && cd build
cmake -DCMAKE_TOOLCHAIN_FILE=$WUT_ROOT/share/wut.toolchain.cmake ../
make
