dear all, I am trying to install the Rmpi library on a cluster but I obtain the following error, which concerns the dynamic libraries: Rmpi version: 0.4-8 Rmpi is an interface (wrapper) to MPI APIs with interactive R slave functionalities. See `library (help=Rmpi)' for details. Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/mypath/.R/library/Rmpi/libs/Rmpi.so": /mypath/.R/library/Rmpi/libs/Rmpi.so: undefined symbol: MPI_Finalize Error in library(Rmpi) : .First.lib failed Error in dyn.unload(x) : dynamic/shared library "/mypath/.R/library/Rmpi/libs/Rmpi.so" was not loaded Is there anybody who can help me in finding a way to trun around the problem.
