sovereignx/INSTALL.md

Follow the OS-specific instructions below.

Linux

Install devkitARM.

Make sure that there is an environment variable called DEVKITARM with the path of the directory before the "bin" directory containing "arm-none-eabi-as", "arm-none-eabi-cpp", "arm-none-eabi-ld" and "arm-none-eabi-objcopy".

Then get the compiler from https://github.com/pret/agbcc and run the following commands.

./build.sh
./install.sh PATH_OF_POKEEMERALD_DIRECTORY

Then in the pokeemerald directory, build the tools.

./build_tools.sh

Finally, build the rom.

make

Windows

Install devkitARM.

Then get the compiled tools from https://github.com/pret/pokeruby-tools. Copy the tools/ folder over the tools/ folder in your pokeemerald directory.

You can then build pokeemerald using make in the MSYS environment provided with devkitARM.

Mac

Installing pokeemerald on a Mac requires macOS >= 10.12 (Sierra or higher).

To get pokeemerald up and running, run the following commands in Terminal:

Make sure you have the right compilers.

xcode-select --install

Download a devkitPRO pacman package (.pkg) and install using the native Installer.

This will install the devkitPRO package in /opt/devkitpro.

You must install devkitARM using

sudo dkp-pacman -S devkitARM 

Then set environment variables

export DEVKITPRO=/opt/devkitpro
echo "export DEVKITPRO=$DEVKITPRO" >> ~/.bashrc
export DEVKITARM=$DEVKITPRO/devkitARM
echo "export DEVKITARM=$DEVKITARM" >> ~/.bashrc

Now download and install the game's compiler from https://github.com/pret/agbcc. You should download and unpack the .zip and move the folder to the same folder holding pokeemerald.

cd /PATH/TO/agbcc/
./build.sh
./install.sh /PATH/TO/pokeemerald 

Build the necessary tools

cd /PATH/TO/pokeemerald
./build_tools.sh

And finally the ROM should be ready to build

make
