Hi,
Not sure whether this is still the case, but the source didn’t build for
me on the Pandora (as of 3 weeks ago, SDL2 revision/Change set 7301 :
3554be091b3b) … because of something in the tests…
In the file SDL_test_fuzzer.c, line #39, before #include I added
#define __USE_ISOC99
… to get it to build.
In fact, building generally on the Pandora was much easier once I
realised that I needed an ext partition not a FAT one 
My notes here
just in case anyone needs to get it building and running:
