Nice to know about the Enterprise variants. FC2/3 and SUSE 9.1 are known good too (did anyone check 9.2 yet?). > One problem that has come up is that if you want to link R with ATLAS, > you need to build shared ATLAS libraries (rather than static).

Actually, you can just go through configuration and add -fPIC to the compiler flags. Then at the end, run ld --shared --whole-archive -o libatlas.so libatlas.a etc. [If you don't accept architectural defaults (as you probably shouldn't), the compile/optimize is going to take a while. I wouldn't know how big the difference is, but -fPIC _will_ force code differences.] > -roger > > Vadim Ogranovich wrote: > > Hi, > > We are planning to buy a 64-bit Linux machine which will mainly run > > R. > > There was an interesting thread on 64-bits on r-help back in April that > > basically confirmed that the 64-bit R is fine as long as the length of > > an atomic object is less than 2^31 - 1. > > My specific question is on which 64-bit Linux distros (SUSE or > > RedHat) > > and processors R is *known* to build out-of-box and run well.
