[R] Compiling R with Intel compilers - recommended options?

[Tim Cutts]

Sorry, I was a bit sparing with details.  Early in the morning, and all 
that.

Many thanks for the swift reply!

Hardware:  700+ machines are 800 MHz Pentium III, 1 GB RAM, Red Hat 7.2
            168 machines are dual 2.8 GHz Xeon, 4 GB RAM, Red Hat 8.0

I'm compiling on the older machines to make sure there won't be library 
problems.

The compiler versions are:

Intel(R) C++ Compiler for 32-bit applications, Version 8.0   Build 
20031016Z Package ID: l_cc_p_8.0.055

Intel(R) Fortran Compiler for 32-bit applications, Version 8.0   Build 
20040412Z Package ID: l_fc_pc_8.

So 12 hours is bit excessive.  :-)  At least now I know.  Thanks!

Ah.  This is indeed 1.9.0, since that is what was asked for.

With 1.9.0, I never get an output file.  On interrupting the make 
check, it says:

make[4]: *** Deleting file `base-Ex.Rout'

and hangs again.  I have to background it and kill it.

The same thing happens with 1.9.1.  I think I'll use gcc/g77 as 
suggested by others to get a working install for now, and then I will 
look into a better optimised version at a more leisurely pace.
