=== | === Environment variables === | ||
You'll need to set some environment variables for both the external libraries, and ScummVM itself. This is so the right compiler and libraries will be used. | |||

=== External libs === | |||
Then, set up any of the external libs you might want. Meaning libMAD for MP3 playback, libFLAC for FLAC support and/or Tremor for Ogg support. You can add mpeg2dec as well, but it's only used for MPEG2 BS1/2 cutscene support and you really should be using the DXA versions instead (can be downloaded from [http://scummvm.org/downloads.php ScummVM's download page]. | |||
Note that you only need to add these if you need support for those filetypes. ScummVM itself will run fine without them. | |||
The below should usually do the trick for these: | |||
./configure --host=arm-darwin --prefix=$SDKROOT/sys/ | ./configure --host=arm-darwin --prefix=$SDKROOT/sys/ | ||
make && make install | make && make install | ||

Then, we need to configure ScummVM itself. | Then, we need to configure ScummVM itself. | ||
./configure --host=iphone \ | |||
--disable-mt32emu --disable-scalers --enable-release \ | |||
--with-flac-prefix=/$SYSROOT/usr/local \ | |||
--with-mad-prefix=/$SYSROOT/usr/local \ | |||
--with-mpeg2-prefix=/$SYSROOT/usr/local \ | |||
--with-tremor-prefix=/$SYSROOT/usr/local | |||
Note that the --with-flac-prefix (and the rest) is only necessary if you want to include support for that specific library. | |||
If you've installed the external libs in any other place than $SYSROOT/usr/local, you need to use that location instead. | |||
== Compiling == | |||
Now, we can start the compile: | |||
make iphone | make iphone | ||
