Building from source
|
|
====================
|
|
This port of ScummVM to the PSP2 is based on SDL2. It uses the open source SDK VITASDK.
|
|
|
|
The dependencies needed to build it are :
|
|
|
|
- The toolchain from https://github.com/vitadev/vdpm
|
|
- zlib, libpng, libjpeg-turbo, libogg, libvorbis, flac, curl, openssl, freetype, from https://github.com/vitadev/vdpm
|
|
- libmad from https://github.com/Cpasjuste/libmad-psp2
|
|
- SDL2 from https://github.com/Cpasjuste/SDL-Vita
|
|
- ScummVM from https://github.com/scummvm/scummvm
|
|
- The fbo branch of libvita2d from https://github.com/frangarcj/vita2dlib/tree/fbo/libvita2d
|
|
copied under new names libvita2d_fbo.a in $VITASDK/arm-vita-eabi/lib and vita2d_fbo.h in $VITASDK/arm-vita-eabi/include. The renaming is necessary to prevent conflict with the official vita2d lib that comes with the VitaSDK.
|
|
- The pre-compiled gtu release of vita-shader-collection from https://github.com/frangarcj/vita-shader-collection/releases, copy all headers to $VITASDK/arm-vita-eabi/include and the library libvitashaders.a to $VITASDK/arm-vita-eabi/lib
|
|
|
|
Once all the dependencies are correctly setup, an installable package can be obtained from source by issuing the following command :
|
|
|
|
./configure --host=psp2 && make psp2vpk
|
|
|
|
