Mohammed,
Either you did not show us the whole error message, or you are missing one
of
the prerequisites. According to line 294 of the 2.0.4 source, you may not
have the make executable in your path.
FYI, you can probably skip most of the first 4 minutes 27 seconds of the
build
by not doing a clean on subsequent builds (just "ant dist").
The default build will also build X10RT. You can add "-DX10RT_MPI=true"
to
the ant command line to have it build the MPI version of X10RT.
