Mednafen Forum: Development => Mednafen 0.9.22-WIP binaries for Mac and how to compile your own

Halt the script on any error.

set -e

Change directory to where the script is being run.

cd `dirname $0`

Root access is needed to install files later.

clear
sleep 0.1
echo "Please enter your password"
sudo sleep 1

Delete the previous temporary directory (if it exists) and make a new one for the Mednafen compile process.

rm -rf ~/mednafen_tmp
mkdir -p ~/mednafen_tmp

Install pkg-config. It's needed for Mednafen to find the libcdio and libsndfile libraries during configure. It's also a useful tool.

unzip -X -q pkg-config_0.26.pkg.zip -d ~/mednafen_tmp/
sudo installer -package ~/mednafen_tmp/pkg-config_0.26.pkg -target /

Download the shared libraries' source code archives to the current directory.

curl -f -S -O http://downloads.xiph.org/releases/flac/flac-1.2.1.tar.gz
curl -f -S -O http://ftp.gnu.org/gnu/libcdio/libcdio-0.83.tar.gz

Extract the downloaded libraries and Mednafen to the temporary directory.

tar -C ~/mednafen_tmp/ -z -x -f flac-1.2.1.tar.gz

Check if this is taking place on Mac OS X 10.5.8. If so, replace masmem.h with a modified version that will compile using gcc 4.0.1.

if [ `uname -r` = 9.8.0 ]; then
	rm ~/mednafen_tmp/mednafen/src/masmem.h
	unzip -X -q masmem.h.zip -d ~/mednafen_tmp/mednafen/src/

Tell configure where to find pkg-config.

export PKG_CONFIG=/opt/pkgconfig/bin/pkg-config
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

Configure, make and install all the libraries.

cd ~/mednafen_tmp/flac-1.2.1
./configure --disable-asm-optimizations
make
sudo make install

cd ~/mednafen_tmp/libogg-1.3.0
./configure
make
sudo make install

cd ~/mednafen_tmp/libvorbis-1.3.3
./configure
make
sudo make install

cd ~/mednafen_tmp/libsndfile-1.0.25/
./configure
make
sudo make install

cd ~/mednafen_tmp/libcdio-0.83/
./configure
make
sudo make install

cd ~/mednafen_tmp/SDL-1.2.15/
./configure
make
sudo make install

cd ~/mednafen_tmp/SDL_net-1.2.8/
./configure
make
sudo make install

Configure and make Mednafen, but don't install it. Installation isn't needed as you'll see in the next steps.

cd ~/mednafen_tmp/mednafen/
./configure --enable-static --disable-shared --disable-jack
make

Create directories and copy the compiled files to those directories.

cd ~/mednafen_tmp/
mkdir -p ~/mednafen_tmp/finished
mkdir -p ~/mednafen_tmp/finished/lib
cp ~/mednafen_tmp/mednafen/src/mednafen ~/mednafen_tmp/finished/
cp ~/mednafen_tmp/mednafen/COPYING ~/mednafen_tmp/finished/

cp /usr/local/lib/libFLAC.8.dylib ~/mednafen_tmp/finished/lib/

cp /usr/local/lib/libvorbis.0.dylib ~/mednafen_tmp/finished/lib/

cp /usr/local/lib/libSDL-1.2.0.dylib ~/mednafen_tmp/finished/lib/

Modify Mednafen and the libraries so that they can find each other. This modification is what makes the libraries shared. (There's probably an easier, more automatic way to do this, but I'm new to the whole Mac compile process using shared libraries.) The path to the libraries in the "lib" folder is relative. For Mednafen to use these libraries they must remain in the "lib" directory which must remain with the "mednafen" executable. Distribute all the files together or Mednafen won't run on a Mac other than the one you just used to compile and install everything.

Open Finder to the "finished" directory where your new files are.

sleep 2
open ~/mednafen_tmp/finished/

This is all very basic scripting. I'm not a programmer and don't really care to improve this script. It worked for me when I compiled Mednafen on my Intel Core 2 Duo Mac Mini. The Mac Mini was running Mac OS X 10.5.8 for the 32-bit compile and Mac OS X 10.6.8 for the 64-bit compile. Both were fresh installs to a USB drive and both had Xcode installed.

To discover which libraries Mednafen requires and which libraries are required by those libraries and so on, I ran "otool -L mednafen" and "otool -L whatever.dylib" from "Terminal." Anything listed with the prefix "/usr/local/lib/" is a library you just installed. Changing that prefix to "@executable_path/whatever/whatever/" converts the library to a shared library.
