The following instructions will only work if building from OS X, using latest XCode with fake signing enabled.

To build RetroArch:
|
|
|
|
|
Open $(root)/ios/RetroArch.xcodeproj, change build type to iOSDevice then choose Product->Build For->Archiving.
|
|
|
|
|
After compilation finishes goto Window->Organizer->Projects->RetroArch then click the small arrow beside
|
|
|
|
|
the Derived Data field, this will open a finder window with the projects build files directory highlighted.
|
|
|
|
|
The app bundle can be found at Build/Products/* in that folder. Use scp to copy the .app bundle to the appropriate place
|
|
|
|
|
on your device.

To build libretro cores:
|
|
|
|
|
In general, to build for iOS devices, copy the configuration for OSX, then at the end add the lines:
|
|
|
|
|
sysroot = -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/
|
|
|
|
|
CC = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv7 $(sysroot)
|
|
|
|
|
CXX = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++ -arch armv7 $(sysroot)
|
|
|
|
|
|
|
|
|
|
Here is how it would look in Makefile.libretro for vba-next:
|
|
|
|
|
...
|
|
|
|
|
else ifeq ($(platform), osx)
|
|
|
|
|
TARGET := vba_next_libretro.dylib
|
|
|
|
|
fpic := -fPIC
|
|
|
|
|
SHARED := -dynamiclib
|
|
|
|
|
ENDIANNESS_DEFINES = -DLSB_FIRST
|
|
|
|
|
else ifeq ($(platform), ios)
|
|
|
|
|
TARGET := vba_next_libretro.dylib
|
|
|
|
|
fpic := -fPIC
|
|
|
|
|
SHARED := -dynamiclib
|
|
|
|
|
ENDIANNESS_DEFINES = -DLSB_FIRST
|
|
|
|
|
|
|
|
|
|
sysroot = -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/
|
|
|
|
|
CC = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv7 $(sysroot)
|
|
|
|
|
CXX = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++ -arch armv7 $(sysroot)
|
|
|
|
|
else ifeq ($(platform), ps3)
|
|
|
|
|
...

|
|
|
Other arm specific flags can be added if needed.
|
|
|
|
|
|
|
|
|
|
Finally issue the make command for the module adding 'platform=ios' at the of the command.
|
|
|
|
|
(e.g. 'make -f Makefile.libretro platform=ios'). Then copy the resulting .dylib file into a sub-directory of the app
|
|
|
|
|
bundle named modules. (e.g. RetroArch.app/modules/vba_next_libretro.dylib).
|
|
|
|
|
|
|
|
|
|
Paths:
|
|
|
|
|
/var/mobile/Library/RetroArch: Will be created to store both saved games and the retroarch.cfg.
|
|
|
|
|
/var/mobile/RetroArchGames: If this exists and is a directory it will be used as the root for game browsing.
|
|
|
|
|
/var/mobile: If RetroArchGames does not exist this will be used as the root for game browsing,
|
|
|
|
|
if another browser root is desired make RetroArchGames a symlink to the preferred path.
|
|
|
|
|
RetroArch.app/shaders: Contains .shader format shaders, sub-directories are supported.
|
|
|
|
|
RetroArch.app/overlays: Contains input overlay definitions, sub-directories are supported.
|
|
|
|
|
RetroArch.app/modules: Contains .dylib files for the libretro modules. The only constraint on the file name
|
|
|
|
|
is that it must end in .dylib, sub-directories are not supported.
|
|
|
|
|
|
|
|
|
|
Simulator:
|
|
|
|
|
To test in iOS Simulator you will need to create the '/var/mobile' directory on you computer, and give yourself full
|
|
|
|
|
access to it.
