RE: Question about Compiling Fluka in 64 bit architecture

Dear Luke,

For the moment there is no public 64bit version of FLUKA, since there is
no gain at all compared with the 32bit version. Therefore the only way
of using it on a 64bit machine is to install all the necessary 32bit
libraries and compile your executable in 32bit mode (from a 64bit
machine). Actually this is the default if you use the standard
compilation scripts of FLUKA (fff, lfluka), otherwise you have to
manually supply the option (-m32) on the compiler (g77 or gcc)

Subject: Question about Compiling Fluka in 64 bit architecture


We are installing Fluka at Indiana University on our new machine to use=20
as part of FLUGG. We would like to compile Fluka in the 64-bit=20
architecture but are not sure if this is possible.

I have searched online and on the fluka website. I found several=20
messages about compiling with 32-bit flags on a 64-bit machine, but can=20
Fluka be compiled directly on a 64-bit machine? If so, what changes do=20
we need to make to accomplish this?

Thank you,

Luke Corwin
