Myoungkyu,
The 'x10c' and 'x10c++' scripts use their own path to figure out the
location of the X10 distribution. However, when you invoke them via
the PATH, they are unable to figure that out (because their own path
is empty). Always specify a path (either relative or absolute) to
the 'x10c' or 'x10c++' invocations, e.g., 'x10.dist/bin/x10c++' or
'/home/mksong/x10-trunk-cuda/x10.dist/bin/x10c++'.
And yes, you also need -DX10RT_CUDA=true.
