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 https://github.com/KallistiOS/KallistiOS.git kos

Enter the toolchain directory:

cd kos/util/dc-chain

Copy over one of the default configuration files:

cp config.mk.sample.testing config.mk

Open config.mk in a text editor and edit the following lines.

toolchains_base=/opt/toolchains/dc/roninchain # Where you want to install the toolchain
pass2_languages=c,c++,objc,obj-c++            # Which languages you want to build support for
thread_model=single                           # support only for single threads
use_kos_patches=0                             # Set this 0 to ensure raw toolchain with no patches
auto_fixup_sh4_newlib=0                       # Set this 0 to ensure raw toolchain with no patches

Download the packages:

./download.sh

Unpack the files:

./unpack.sh

And finally, build the toolchain. Do not use make alone or the build script will patch the toolchain with KOS patches, which is not what we want here!

make

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 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.
