Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

sdl_gen_config.lua
|
|
|
|
Given a series of set configuration values from the project definitions,
|
|
this file contains a series of functions that generate valid preprocessor
|
|
definitions to enable or disable various features of the SDL2 library. These
|
|
definitions are pasted into a template SDL config header file, which is then
|
|
saved in the local directory and referenced to in generated project files.
|
|
|
|
This file depends on sdl_file.lua.
