After cloning the repo, put a copy of the target archive(s) in their correct version folder in base/.
For example, if your target archive is libgultra_rom.a 2.0L then you'd place it in base/L/.
If you will be building without a target archive by setting COMPARE=0 then you can skip this step.
The build process requires the following packages:
- build-essential
- python3
- binutils-mips-linux-gnu (libultra* only)
Under Debian / Ubunutu you can install them with the following commands:
sudo apt update
sudo apt install build-essential python3If building any libultra you can install binutils-mips-linux-gnu with:
sudo apt install binutils-mips-linux-gnuRun make setup with the proper flags set followed by make with optional jobs. For example, if building the 2.0L PC archive you'd do the following:
make VERSION=L TARGET=libgultra_rom setupmake VERSION=L TARGET=libgultra_rom
Every target flag combination requires separate a setup command.
If building without an target archive, than you can use COMPARE=0 like the the following:
make VERSION=L TARGET=libgultra_rom COMPARE=0 setupmake VERSION=L TARGET=libgultra_rom COMPARE=0
note that running setup without COMPARE=0 and no archive will result in an error,
and only needs to be run once instead of per target flag combination
If building for use with modern linkers, than you can use FIXUPS=1 like the the following:
make VERSION=L TARGET=libgultra_rom FIXUPS=1 setupmake VERSION=L TARGET=libgultra_rom FIXUPS=1
note that running with FIXUPS=1 will automatically set COMPARE=0.
