To install the required tools, follow these steps:

Install the necessary packages by running the following command in your terminal: bash sudo apt update sudo apt install build-essential gcc-9.3 g++-9.3 libssl-dev
Install the Mesa 3D graphics library, which is required for the Mesa Turnip Drivers: bash sudo apt install mesa-utils libgl1-mesa-dev
Clone the DolRecomp repository from GitHub: bash git clone https://github.com/dolphin-emu/dolrecomp.git
Navigate to the DolRecomp repository and install the required dependencies: bash cd dolrecomp make
Build the DolRecomp tool: bash make build

Setting Up the Development Environment

To set up the development environment, follow these steps:

Create a new directory for your project: bash mkdir my_project
Navigate to the project directory: bash cd my_project
Create a new file called Makefile with the following content: makefile CC=gcc-9.3 CXX=g++-9.3 CFLAGS=-std=c++17 -O3 -m64 -march=native -mtune=native -fvisibility=hidden -fvisibility-inlines-hidden -Wall -Wextra -Werror CXXFLAGS=$(CFLAGS) -std=c++17 -O3 -m64 -march=native -mtune=native -fvisibility=hidden -fvisibility-inlines-hidden -Wall -Wextra -Werror LDFLAGS=-L/usr/lib/x86_64-linux-gnu

dolrecomp: dolrecomp.cpp $(CXX) $(CXXFLAGS) -o $@ $^ $(LDFLAGS)

clean: rm -f dolrecomp

Create a new file called dolrecomp.cpp with the following content: cpp

include

int main() { // Initialize DolRecomp dolrecomp_init();

// Recompile the DOL
dolrecomp_recompile("path/to/dol.dol");

// Clean up
dolrecomp_cleanup();

return 0;

}

Replace "path/to/dol.dol" with the actual path to the GameCube / Wii DOL you wish to recompile.

Initializing DolRecomp

To initialize DolRecomp, follow these steps:

Call the dolrecomp_init() function in your main() function: cpp int main() { dolrecomp_init(); // Recompile the DOL dolrecomp_recompile("path/to/dol.dol"); // Clean up dolrecomp_cleanup(); return 0; }
