[R] enable-R-shlib ?

2007-04-11 Thread Bernardo Rangel Tura

Hi R Masters!


Recently I migrated to Ubuntu Linux [I a former windows user].

Now I think compile a 64-bit R version for my computer [Turion AMD], but
I not sure if using the configure option --enable-R-shlib.

I note this option is usefull for some GUI like gnomeGui and JGR, but
this will go penalty performace so I ask:

1- I must using this option?

2- If I using this option, have an another option wich i gain performace
[like --enable-Blas]?

Thanks for all

You'll find the definitive discussion in the R-admin manual.

No: it is not even the default.

There is no such option, but the most useful thing you can do is to add an 
optimized BLAS: again see the R-admin manual.

 Thanks for all
