Compiling ScummVM/PlayStation 2Compiling ScummVM/PlayStation 2

# a. Decide were your tools and your SDK are going to be ;-)

 For example:
/works/devel/ps2/tools
/works/devel/ps2/sdk


# b. First we need the tools, let's get them started with git...

git clone https://github.com/ps2dev/ps2toolchain.git

# c. ...and build them using toolchain.sh!

Make sure that you have the correct env settings

For me:

 export PS2DEV=/works/devel/ps2/tools
export PATH=$PATH:$PS2DEV/bin
export PATH=$PATH:$PS2DEV/ee/bin
export PATH=$PATH:$PS2DEV/iop/bin
export PATH=$PATH:$PS2DEV/dvp/bin
export PS2SDK=/works/devel/ps2/sdk
export PATH=$PATH:$PS2SDK/bin


You will need them in the future too (not only to create the tools) so you might want to add them to your profile.

Note: the script will download the needed sources from the net. As of right now, the PS2 port won't compile with the most recent versions of the toolchain so you will have to modify the scripts "005-ps2sdk.sh" and "006-ps2client.sh" to svn check out revision 1628 or earlier.

You won't need most of "ps2toolchain" after building but be sure to save the ps2sdk source (from ps2toolchain/build/ps2sdk) because some other libs (eg. SjPcm) rely on it. I suggest keeping it in /works/devel/ps2/sdk and export:

export PS2SDKSRC=/works/devel/ps2/sdk-src

# d. Nearly there! Now we still need some extra libs which are not provided with default SDK:

- I suggest storing all of them in "sdk-extra" so that you just need to edit one line in Makefile.ps2 to compile scummvm

- you can call it "sdk-ports" if you want to be consistent with svn naming structures

    // zlib & libmad
git clone https://github.com/ps2dev/ps2sdk-ports.git
cd zlib
make
mkdir ee/lib
make

    // Tremor (unoptimized)
mkdir tremor
cd tremor
svn co http://svn.xiph.org/trunk/Tremor/
make

    // sjcpm (unoptimized)
mkdir ps2_sdk_old
cd ps2_sdk_old
git clone https://github.com/AzagraMac/PS2_SDK.git
cd isjcpm
make


# e. get ScummVM

git clone https://github.com/scummvm/scummvm.git

-or-

git clone -b branch-1-7-0 https://github.com/scummvm/scummvm.git
cd trunk/backends/platform/ps2

edit Makefile.ps2 to match your sdk-extra (for example: PS2_EXTRA = /works/devel/ps2/sdk-extra)

make -f Makefile.ps2

Your fresh-baked ScummVM will be waiting for you in elf/scummvm.elf ;-) If you don't need the symbols, just strip them ee-strip --strip-all scummvm.elf

Enjoy!
