To be honest. Just give it a build then. I did a tweak or two (which I obliquely alluded to above) to make it more kindle specific. Perhaps I broke it.
It's way easy:
Git down
http://buildroot.uclibc.org/git.html (buildroot)
properly configure. (simple there are a bunch of threads of mine on that but yeah easy)
Drop the patch in the package folder in buildroot under {buildroot}/package/sdl-1.2.5/
make xconfig (shell)
pick SDL as a package.
make
grab from {buildroot}/output/target/usr/lib
That's all I did
Sorry I cant be more help. Without the device it would be crystal ball time.
(OR just cross compile it the old fashioned way
)
