[kepler-users] How To Build Kepler under Eclipse Instructions

[Matt Jones]

Hi,

I agree the demos should work.  But the R problem is one we've
discussed.  The Kepler installer puts R in place when Kepler is
installed, so users should not encounter the problem that Edward did.
Developers that are using SVN need to install R themselves.  The
'null' message that you got is a problem that I thought we had fixed.
I entered a bug request that makes the R actor produce a more
intelligible error message when it can't find the R executable.  Maybe
in init() it should be doing a test of whether R is available and
reporting a sensible error if it is not.  This could also be solved
withthe dependency tracking system that we are designing for modules.
