Fatal error: Unable to open the base package
So, now I have managed to compile the hello program of RInside on WindowsXP (VirtualBox). But, when I click on its executable, I get a dialogbox showing the above error.
Searching Google led me to this thread where they were talking about the following settings.
R:

The order of precedence for environmental variables is the order in which these options are listed, that is the command line then .Renviron then the inherited environment.

Please point out the point that I am missing.
Answer
This error will get a little help in the next release. What happens is that when the RInside CRAN package gets built, R_HOME is detected and compiled in. With the value of the build machine. Ie not yours.
The answer is to a) build RInside locally so that it stores your R_HOME value or b) to set an enviroment variable R_HOME [ and needed only on Windows as only Windows can give you prebuilt versions ]. In the next version we'll also use some code from R to look in the registry for you; see the SVN repo.
This question has however been asked and addressed numerous times before.
