Hi, sorry for not giving you a timely reply to your previous mail.
The first resource to check in debugging is the debug logs. Unfortunately, on the various versions of Windows, these are installed to different, rather obscure places. Search for files with names starting with rkward.frontend and rkward.rbackend Usually somewhere inside your home directory (but could also be in the system- wide temporary folder). You can increase verbosity of these logs by starting rkward with --debug-level 4 (or 5) from the command line. My guess is that there is a rather fundamental problem with invoking the backend executable, for whatever reason. The first function to look at, here, is RKFrontendTransmitter::run() (rbackend/rkfrontendtransmitter.cpp).

If so, there is probably a global emerge option to control this. Personally, I compile rkward without using emerge on Windows. To start rkward through a debugger, use the --debugger 'path/to/gdb.exe' option. I am not entirely sure whether that will work on Windows ATM, though (usually it's easier to start normally, and then attach gdb afterwards, using the --pid option. But of course that does not work for problems during startup). If it does not, edit rkward.bat to call the debugger, properly. > Its evidently machine dependent, doesn't > have anything to with multiple R installations and seems to effect my HP > Pavilion Elite dt2000t with a Nvidia only. That's why my first guess would be that some piece of software on this machine prevents rkward from starting the backend, somehow. Regards Thomas
