Compiling ScummVM/Maemo

Compiling ScummVM for Maemo

This page describes how you build Maemo packages from the ScummVM source code tree.

Preparation

Compilation should be done on a Linux machine running Debian/Ubuntu.
For other operating systems, a Linux virtual machine running Debian/Ubuntu can be used instead.

The process is based on this document.

Download and Install Maemo SDK

Note: The following instructions are based on an attempt in a fresh Debian 5 (lenny) i386 install

Add the following line to /etc/apt/sources.list:

deb http://maemo-sdk.garage.maemo.org/download/host debian-lenny free

Then run the following commands to install the SDK:

sudo apt-get update
sudo apt-get install maemo-sdk

Then run the following commands to build/install the tools and compilers:

maemo-sdk reload catalogue
sudo maemo-sdk --mirror "http://archive.debian.org/debian/" install tools lenny-2009-1
sudo maemo-sdk install toolchain arm-2007q3
maemo-sdk install rootstrap diablo4.1.2_armel

Install dependencies inside the SDK environment

You'll need to install the maemo extras repo to the rootstrap. Add the following line to ~/.maemo-sdk/rootstraps/armel/diablo4.1.2_armel/etc/apt/sources.list

 deb http://repository.maemo.org/extras/ diablo free non-free

and then install the dependencies:

sb2 -eR apt-get update
sb2 -eR apt-get install libflac-dev libmad0-dev libmpeg2-4-dev libvorbisidec-dev

Optional: Install git inside SDK environment

The ScummVM makefile has an optional dependency on git. It uses it as part of populating the version. The git installed on the host operating system is not visible to the SDK environment.

Download the armel git deb from here (thanks Nikosapi) mirror

Install it by running:

 sb2 -eR dpkg -i git_1.6.2-1_armel.deb

Optional: Install libfaad-dev inside SDK environment

Note: this step is very optional as no stable games currently need AAC decoding (as of 1.8.0). It is included here for posterity.

The libfaad version that's in maemo-extras is outdated and so we need to use the Lenny one (without the debian patches that make it unbuildable in maemo) and without dynamically linking to it so that it doesn't become a runtime dependency that's not available in maemo-extras.

 mkdir faad
 cd faad
 apt-get source libfaad-dev
 cd faad2-2.6.1/
 sb2 ./bootstrap

Remove these lines from debian/patches/00list: 02_public-headers, 99_autotools-regenerated. These patches make it unbuildable in maemo.

 sb2 dpkg-buildpackage -b
 sb2 -eR dpkg -i ../libfaad*.deb

Then we delete the libfaad.so from the SDK environment so that it statically links to libfaad.a

 rm ~/.maemo-sdk/rootstraps/armel/diablo4.1.2_armel/usr/lib/libfaad.so*

Ensure Packaging Files Are Available In Source Tree Root

This requires a symlink from backends/platform/maemo/debian to the root of the scummvm checkout:

ln -s backends/platform/maemo/debian 

Compile

Depending on what you want, choose one of the following. If you're not sure, choose the first one.

Build Package

sb2 dpkg-buildpackage -b

Compile (Without Building Package)

sb2 ./configure --host=maemo
sb2 make
