-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi
I know this has been asked before, but I can not find it - so my apologies. I want to compile R myself, to optimize it for speed. There is a small section (a few lines actually) in the R-admin manual (Compilation-flags) which states that the LDFLAGS "on recent systems ‘'-Bdirect,--hash-style=both,-Wl,-O1'’ is recommended". But I set LDFLAGS, and it is actually slightly slower then the Ubuntu binary. So are there any other ressources (probably HotTos?) on how I can tune the compilation of R to make it faster? I am using Maverick, and R info is below: ############ > sessionInfo() R version 2.12.0 (2010-10-15) Platform: i686-pc-linux-gnu (32-bit) locale: [1] LC_CTYPE=en_US.utf8 LC_NUMERIC=C [3] LC_TIME=en_US.utf8 LC_COLLATE=en_US.utf8 [5] LC_MONETARY=C LC_MESSAGES=en_US.utf8 [7] LC_PAPER=en_US.utf8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.utf8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] tools_2.12.0 > version _ platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 2 minor 12.0 year 2010 month 10 day 15 svn rev 53317 language R version.string R version 2.12.0 (2010-10-15) ############ Thanks, Rainer - -- Rainer M.
