Cross-compilers versus windows compilers (was optimal win dows R machine)

May I ask a naive follow up to this? Having now been granted limited rights to use R-windows on a work PC, I wish to set up my home PC to support compiling packages and so on. I currently have a working Linux set-up at home, is there any general advice as to whether it would be better to add in the cross-compilers there or is it better to persuade my home PC to dual boot windows and set up the full recommended windows compilation collection.
If you don't need Compiled HTML help (and my guess is that you don't) then almost all packages can be cross-compiled. (Of course, almost all the public ones are already available in compiled form: many thanks to Phillipe Grosjean for updates while I am travelling etc.) Setting up a cross-compiler can be at least as frustrating as setting up a native one. I am offering one on the Rtools portal that works for me, but is a little out-of-date. There are others out there, but they mostly lack Fortran. I would try the cross-compiling route for now, but would warn that as we move to using R itself for parts of the build procedure, cross-compiling may become less viable. Indeed, I managed to break it in R-devel for a week or so recently. PS on the original topic about VMware: my comments were principally about speed running R for Windows under VMware. It is probable that R is a particularly bad fit, as its memory manager is already trying to make Windows memomry management work like the Unix equivalent, and memory management is crucial to R's performance.
Thanks for any pointers Paul
From: Liaw, Andy (andy_liaw at merck.com) Date: Wed Oct 17 2001 - 16:41:24 CEST I agree with Mark about Linux, if for no other reasons than the fact that
it
actually comes with the compilers needed to build R and do further code development. Compared with doing it on Linux, compiling R from source on Windows is not exactly a pleasure, even with the tremendous work to make it
even possible by Ripley and Mararrato. Cheers, Andy
