## Prerequisites
|
|
|
|
| Linux | macOS | Windows 10 (build 18917+) | Windows 10 (1709+) | Windows Vista, 7, 8, 8.1, and 10 (1507, 1511, 1607, 1703)
|
|
| ----- | ----- | ------------------------- | ------------------ | ---------------------------------------------------------
|
|
| none | [Xcode Command Line Tools package][xcode] | [Windows Subsystem for Linux 2][wsl2] | [Windows Subsystem for Linux][wsl] | MSYS2 (see below)

|
|
[wsl]: https://docs.microsoft.com/windows/wsl/install-win10
|
|
|
|
The [prerelease version of the Linux subsystem](https://docs.microsoft.com/windows/wsl/install-legacy) available in the 1607 and 1703 releases of Windows 10 is obsolete so consider uninstalling it.
|
|
|
|
Make sure that the `build-essential`, `git`, and `libpng-dev` packages are installed. The `build-essential` package includes the `make`, `gcc-core`, and `g++` packages so they do not have to be obtained separately. MSYS2 does not include `libpng-dev` so it must be built from source.
|
|
|
|
Install the **devkitARM** toolchain of [devkitPro](https://devkitpro.org/wiki/Getting_Started) and add its environment variables. For Windows versions without the Linux subsystem, the devkitPro [graphical installer](https://github.com/devkitPro/installer/releases) includes a preconfigured MSYS2 environment, thus the steps below are not required.
|
|
|
|
export DEVKITPRO=/opt/devkitpro
|
|
echo "export DEVKITPRO=$DEVKITPRO" >> ~/.bashrc
|
|
export DEVKITARM=$DEVKITPRO/devkitARM
|
|
echo "export DEVKITARM=$DEVKITARM" >> ~/.bashrc
|
|

## Installation
|
|
|
|
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
|
|
./build_tools.sh
|
|
|
|
If the repository was previously set up using Cygwin, delete the `.exe` files in the subfolders of the `tools` folder except for `agbcc` and run the `build_tools.sh` script again.
|
|
|
|
To build **pokeemerald.gba**:
|
|
|
|
make -j$(nproc)
|
|
|
|
To confirm it matches the official ROM image while building, do this instead:
|
|
|
|
make compare -j$(nproc)
|
|
|
|
If only `.c` or `.s` files were changed, turn off the dependency scanning temporarily. Changes to any other files will be ignored and the build will either fail or not reflect those changes.
|
|
|
|
make -j$(nproc) NODEP=1
|
|
|
|
**Note:** If the build command is not recognized on Linux, including the Linux environment used within Windows, run `nproc` and replace `$(nproc)` with the returned value (e.g.: `make -j4`). Because `nproc` is not available on macOS, the alternative is `sysctl -n hw.ncpu`.
|
|
|
|
**Note 2:** If the base tools are not found on macOS 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.
