[Ohrrpgce] Android port

Wed Jun 5 08:46:43 PDT 2013

For some reason, the latest commits (which seem mostly benign) are
giving me some errors when I try to compile the ohrrpgce:

I edited compile-using-toolchain.sh and changed:
   cd .. && scons fbc=$FBC android=1 debug=1 unlump relump reload vectortest
...to:
   cd .. && scons fbc=$FBC android=1 debug=1 unlump relump reload
vectortest game

Now I get the following:

/home/sethhetu/android-tmc-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld:
error: cannot find -lSDL
/home/sethhetu/android-tmc-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld:
error: cannot find -lSDL
/home/sethhetu/android-tmc-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld:
error: cannot find -lSDL_mixer
(full log: http://pastie.org/8010539)

If I try to run just "scons fbc=path/to/fbc android-source=1 debug=1
game" then it works.

Is this expected? Should I not add "game" as a target to
compile-using-toolchain.sh?

Also, it might make sense to have compile-using-toolchain.sh take a
list of scons targets, e.g.:
   ./compile-using-toolchain.sh   game vectortest
