Every time Xcode 5 compiles NXEngine-iOS, I get an error in SDL:
NXEngine-iOS/iOS/deps/SDL/src/render/opengles2/SDL_gles2funcs.h:35:1: Assigning to 'void ()(GLuint, GLsizei, const char *, const GLint )' from incompatible type 'void (GLuint, GLsizei, const GLchar *const *, const GLint *)': type mismatch at 3rd parameter ('const char *' vs 'const GLchar *const *' (aka 'const char *const *'))
The code is at line 35 in SDL_gles2funcs.h:
SDL_PROC(void, glShaderSource, (GLuint, GLsizei, const char **, const GLint *))
Just as a side note: It compiles without any errors in Xcode 4.6. Only 5.0 & 5.1 create errors.
