With R-3.0.1 Loading required package: Rmpi Failed with error: ‘package ‘Rmpi’ was built before R 3.0.0: please re-install it’
And when I try to reinstall Rmpi, I get this <after a whole bunch of 'yes's> .... checking mpi.h usability... no checking mpi.h presence... no checking for mpi.h... no configure: error: "Cannot find mpi.h header file" ERROR: configuration failed for package ‘Rmpi’ And attempting to go back.... With R-2.15.3, I get these warnings: Warning messages: 1: package ‘gbm’ was built under R version 3.0.1 2: package ‘survival’ was built under R version 3.0.1 [1] "Error in socketConnection(\"localhost\", port = port, server = TRUE, blocking = TRUE, : \n cannot open the connection\n" So there's no going back. Where do I look for reasons why Rmpi can't find mpi.h header even though it was findable before 3.0.1? I know not to take that message too literally since there is a file mpi.h that bash can find. Something else is being hinted at but what? > sessionInfo() R version 3.0.1 (2013-05-16) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_NZ.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_NZ.UTF-8 LC_COLLATE=en_NZ.UTF-8 [5] LC_MONETARY=en_NZ.UTF-8 LC_MESSAGES=en_NZ.UTF-8 [7] LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_NZ.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] parallel splines grDevices utils stats graphics methods [8] base other attached packages: [1] gbm_2.1 survival_2.37-4 cairoDevice_2.19 lattice_0.20-15 loaded via a namespace (and not attached): [1] grid_3.0.1 multicore_0.1-7 > TIA -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Average minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
