Building a toolchain for libronin

The standard KallistiOS sh-elf toolchain contains patches that prevent it from working with libronin; however, KallistiOS's dc-chain script can be used to easily build a libronin-compatible raw toolchain. You can build this toolchain to a separate directory than an existing KallistiOS toolchain.

Create a directory to hold the toolchain and give yourself ownership:

sudo mkdir -p /opt/toolchains/dc/roninchain
sudo chown -R $USER:$USER /opt/toolchains/dc/roninchain

Clone the KallistiOS repo somewhere convenient:

git clone kos

Enter the toolchain directory:

cd kos/util/dc-chain

Alter the Makefile.cfg options in a text editor if you'd like.

And finally, download and build the toolchain for libronin use with the following command:

make all enable_objc=0 enable_objcpp=0 thread_model=single use_kos_patches=0 auto_fixup_sh4_newlib=0 sh_toolchain_path=/opt/toolchains/dc/roninchain/sh-elf arm_toolchain_path=/opt/toolchains/dc/roninchain/arm-eabi

You can now use the compilers stored at /opt/toolchains/dc/roninchain/sh-elf/bin and /opt/toolchains/dc/roninchain/arm-eabi/bin to compile libronin. You may need to modify Makefile and zlib/Makefile included with libronin to include the path to the compilers.

You may delete the kos folder that you cloned using git earlier once your toolchain is successfully installed.
