iOS Support / RetroArch

[jet082]

XProger#15

This seems to suggest that the only things left for iOS support are keyboard/mouse support. However, trying to build the libretro core shows that openlara relies upon EGL

Error here:

./../../gapi_gl.h:26:14: fatal error: 'EGL/egl.h' file not found

I attempted to include https://github.com/alco/EGL_mac_ios but that did not seem to be sufficient.

You can fix this by doing the following:

1. In src/platform/libretro/Makefile

CFLAGS += -DHAVE_OPENGLES -DHAVE_OPENGLES2 $(DEFINES)

to

EXTRA_GL_LIBS := -framework OpenGLES
CFLAGS += -DHAVE_OPENGLES -DHAVE_OPENGLES2 -Wno-error=implicit-function-declaration $(DEFINES)

----

CC = cc -arch armv7 -isysroot $(IOSSDK)

to

CC = cc -arch arm64 -isysroot $(IOSSDK)

----

CXX = c++ -arch armv7 -isysroot $(IOSSDK)

to

CXX = c++ -arch arm64 -isysroot $(IOSSDK)

----

ifeq ($(platform),ios9)

to

ifeq ($(platform),ios-arm64)

----

Remove these lines beneath ifeq ($(GLES), 1):

LIBS += -lGLESv2 # Still link against GLESv2 when using GLES3 API, at least on desktop Linux.
LIBS += -lEGL

2. In src/gapi_gl.h

#elif __LIBRETRO_GLES__

to

#elif __LIBRETRO_GLES__ && false

----

#include <OpenGLES/ES2/gl.h>
#include <OpenGLES/ES2/glext.h>
#include <OpenGLES/ES3/glext.h>

to

#include <OpenGLES/ES3/gl.h>

----

Remove the line:

#undef  GL_RG
