Compiling ScummVM/macOS

Compiling ScummVM under OS X

Compiling ScummVM under OS X requires setting up the build environment first, and then compiling the sources either via command line, or the XCode GUI

Things needed

XCode

This can be installed from the Apple Store

XCode command line tools

After installing XCode, open a terminal and type

xcode-select --install

Package manager

Getting the required libraries is easier with a package manager. The three most well-known ones are MacPorts, Homebrew and Fink.

1. MacPorts

Get the MacPorts installer for your OS X version from the MacPorts installation page

2. Homebrew

You can install homebrew by pasting the following into a terminal:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3. Fink

You can install Fink by downloading and building the source from the Fink Source Release page

Obtaining the required libraries

After downloading the XCode command line tools and a package manager, enter the following command to install all the required libraries:

1. MacPorts

sudo port install libsdl libjpeg-turbo libmpeg2 libogg libvorbis flac libmad libpng libtheora faad2 freetype zlib fluidsynth

2. Homebrew

brew install sdl jpeg-turbo libmpeg2 libogg libvorbis flac libmad libpng theora faad2 freetype lzlib fluid-synth

3. Fink

4. Manual compilation

Get the source code from the libraries. With this method you will not only need to get the libraries ScummVM uses directly, but also those they depend on.

Required:
- SDL 1.2 or SDL 2
Optional:
- zlib
- jpeg
- libpng
- libogg and libvorbis
- FLAC
- libmad
- mpeg2
- FAAD2
- Theora
- For Freetype
  - bzip2
  - FreeType
- For Fluidsynth
  - pkg-config
  - libffi
  - gettext
  - glib
  - FluidSynth

All the libraries are compiled and installed in the same way:

cd thelib-src
./configure --prefix=/path/to/install
make
make install

The default installation path is /usr/local, but you will need admin privileges to install the libraries in this location.

cd thelib-src
./configure
make
sudo make install

If you want your compilation to be compatible with older system, use the -mmacosx-version-min flag (for example -mmacosx-version-min=10.5). To force compilation in 32 bits use -arch i386. You can do that by setting environment variables before compiling all the libraries and ScummVM:

export LDFLAGS="-arch i386 -mmacosx-version-min=10.5"
export CFLAGS="-arch i386 -mmacosx-version-min=10.5"
export CXXFLAGS="-arch i386 -mmacosx-version-min=10.5"

bzip2 is an exception. There is no configure and you directly call make with options. For example:

make CFLAGS="-arch i386 -mmacosx-version-min=10.5 -Wall -Winline -O2 -g -D_FILE_OFFSET_BITS=64" LDFLAGS="-arch i386 -mmacosx-version-min=10.5"
make install PREFIX=/Users/criezy/Dev/scummvm-releases/libs

If you plan to build the ScummVM app bundle, you will need to generate static libraries. For most of the libraries this is done by default, but for a few you need to specify you want static libraries when invoking configure. Here are suggested configure options for each library. If the library is not listed in the table below this means the default is fine.

Library	configure flags	Comments
pkg-config	--with-internal-glib
glib	--enable-static
libmpeg2	--disable-sdl	Need to add -std=gnu89 to CFLAGS (for example 'export CFLAGS="-std=gnu89"' before invoking configure)
FLAC	--enable-static --disable-asm-optimizations
Theora	--disable-examples	Need to edit configure before running it to remove flag -fforce-addr Examples do not compile with libpng 1.6

Compiling ScummVM via the command line

Configuring ScummVM

Run the configure script:

./configure

If no errors come up, you should be ready to compile ScummvM. For a list of optional features (eg additional, not yet enabled engines) run:

./configure --help

Here is a list of some options you may want to use:

--enable-all-engines or --enable-engine=foo,bar to enable unsupported engines (not compiled by default)
--with-staticlib=/path/to/install/dir if your libraries are not in a standard place (e.g. you compiled the libraries manually with a custom installation directory). This is only used when building the application bundle.
--enable-updates --with-sparkle-prefix=/path/to/sparkle to enable Sparkle (disabled by default). The path should be the path to the directory that contains the Sparkle.framework and not the path to the Sparkle.framework itself.

Note: If you want to use Sparkle, there are some additional steps to do such as setting up DSA signatures. See [1] for details. ScummVM expects to find the DSA public key in dist/macosx.dsa_pub.pem.
