Independently from the specific OS, make sure that the gcc, g++, make, git, and libpng-dev packages or their equivalents are installed and accessible to the development tools that are used by the project (this means that, for example, on Windows, the packages have to be installed in the WSL environment). The package names and installation methods may vary with each OS.
Install the devkitARM toolchain of devkitPro as per the instructions on their wiki. On Windows, follow the Linux instructions inside WSL as any steps about the Windows installer do not apply.
Debian-based distro users: This applies to Debian, Ubuntu, and similar distros, including in WSL. If necessary, install the libarchive13, pkg-config, and gdebi-core packages to be able to install devkitPro.
Windows 10 users: WSL 2 is available in the 1903 release (build 18362) and later, therefore existing WSL 1 and prerelease WSL users are recommended to update. Right-click the Start button or press Win+X, choose Run, and run ms-settings:about to determine the Windows version. Also check Windows Update to make sure your installation is up-to-date.
Windows 7 and 8.1 users: pret is no longer focusing on support in pokeemerald for old versions of Windows so consider upgrading to a current release of Windows 10 or try a third-party guide like this one instead.
To set up the repository:
git clone https://github.com/pret/pokeemerald
git clone https://github.com/pret/agbcc
cd ./agbcc
./build.sh
./install.sh ../pokeemerald
cd ../pokeemerald
To build pokeemerald.gba for the first time and confirm it matches the official ROM image:
make compare
If an OK is returned, then the installation went smoothly.
Windows users: Consider adding exceptions for the pokeemerald and agbcc folders in Windows Security using these instructions. This prevents Microsoft Defender from scanning them which might improve performance while building.
To build pokeemerald.gba with your changes:
make
macOS users: If the base tools are not found in new Terminal sessions after the first successful build, run echo "if [ -f ~/.bashrc ]; then . ~/.bashrc; fi" >> ~/.bash_profile once to prevent the issue from occurring again. Verify that the devkitarm-rules package is installed as well; if not, install it by running sudo dkp-pacman -S devkitarm-rules.
See the GNU docs and this Stack Exchange thread for more information.
To speed up building, run:
make -j$(nproc)
nproc is not available on macOS. The alternative is sysctl -n hw.ncpu (relevant Stack Overflow thread).
To build pokeemerald.elf with enhanced debug info:
make DINFO=1
This project supports the arm-none-eabi-gcc compiler included with devkitARM r52. To build this target, simply run:
make modern
To build using a toolchain other than devkitARM, override the TOOLCHAIN environment variable with the path to your toolchain, which must contain the subdirectory bin.
make TOOLCHAIN="/path/to/toolchain/here"
The following is an example:
make TOOLCHAIN="/usr/local/arm-none-eabi"
To compile the modern target with this toolchain, the subdirectories lib, include, and arm-none-eabi must also be present.
