Dreamcast Build
Note you will need GIT installed to download/update the latest toolchain files.
This is the path used in the default Makefile you may need to make /opt too depending on system. Note sudo is used and you will have to provide your password for access.
$ sudo mkdir /opt/toolchains
[sudo] password for myusername: ....This ensure your user can read/write the files and folders during build appropriately. 'myusername' is the username you use to log-in to the system. Run whoami if you are unsure of your username.
$ sudo chown myusername:myusername /opt/toolchainsClone the KallistiOS and kos-ports repositories into the toolchains folder.
$ cd /opt/toolchains
toolchains$ git clone git://cadcdev.git.sourceforge.net/gitroot/cadcdev/KallistiOS
# ... download of KallistiOS here ...
toolchains$ git clone --recursive git://cadcdev.git.sourceforge.net/gitroot/cadcdev/kos-ports
# ... lots of downloading and submodule updates here ...Next download the dc-toolchain tools that will be built for the DC architecture.
toolchains$ cd KallistiOS/utils/dc-chain
dc-chain$ ./download.sh
# ... download of binutils, gcc, newlib ...Next run the unpack.sh script to decompress all the source downloads.
dc-chain$ ./unpack.sh
# ... unpacks silently for awhile ...This process can take awhile, you might want to go for a coffee.. :)
dc-chain$ make
# ... patching ...
# ... lots of compiling ...
To prepare the environ.sh file, create /opt/toolchains/KallistiOS/environ.sh and enter the following:
# Note: modified version of /opt/toolchains/KallistiOS/doc/environ.sh.sample, comments removed:
export KOS_ARCH="dreamcast"
export KOS_SUBARCH="pristine"
export KOS_BASE="/opt/toolchains/KallistiOS"
export KOS_PORTS="/opt/toolchains/kos-ports"
export KOS_MAKE="make"
export KOS_LOADER="dc-tool -x"
export KOS_GENROMFS="${KOS_BASE}/utils/genromfs/genromfs"
export KOS_CC_BASE="/opt/toolchains/dc/sh-elf"
export KOS_CC_PREFIX="sh-elf"
export DC_ARM_BASE="/opt/toolchains/dc/arm-eabi"
export DC_ARM_PREFIX="arm-eabi"
export PATH="${PATH}:${KOS_CC_BASE}/bin:/usr/local/dc/bin"
export KOS_INC_PATHS="-I${KOS_PORTS}/include"
export KOS_CFLAGS=""
export KOS_CPPFLAGS=""
export KOS_LDFLAGS=""
export KOS_AFLAGS=""
export KOS_CFLAGS="-O2 -fomit-frame-pointer"
. ${KOS_BASE}/environ_base.sh
Now that the toolchain is prepared KOS and KOS ports can be built.
Build KOS by sourcing the environ.sh file and building it with make.
$ cd /opt/toolchains/KallistiOS/
KallistiOS$ source ./environ.sh
KallistiOS$ make
# ... bunch of compiling ...
Next change to the kos-ports directory build the source.
KallistiOS$ cd /opt/toolchains/kos-ports/
kos-ports$ make
# ... bunch of compiling ...
To avoid having to source the envion.sh file for each new terminal, add it to your .bashrc file.
Edit (or create) your ~/.bashrc file and add the following at the end:
source /opt/toolchains/KallistiOS/environ.shAt this point KOS and the KOS ports should be ready to use.
Use GIT to fetch the KallistiOS and kos-ports repositories. Using example target directory of ~/Dreamcast, you can place it anywhere.
$ mkdir ~/Dreamcast
$ cd ~/Dreamcast
# Note: current DC activity is in the dreamcast-experimental branch, instructions will change
Dreamcast$ git clone git://github.com/cjcliffe/CubicVR.git -b dreamcast-experimental
... git checkout ...Change to the CubicVR repository directory and build it.
$ cd ~/Dreamcast/CubicVR/dreamcast/
$ make
# ... bullet is compiled ...
# ... CubicVR is compiled ...CubicVR is now built and ready for use.
