Guiseppe
Thanks for the information thus far. I need further understanding of:
Question RE: require 32bit libraries:
What are typical distinguishing names of cogent 32bit and 64 bit libraries?
My system is Ubuntu, Feisty release and
Jacques uses Redhat mostly at CERN
Question RE: compatible option enabled in kernel configuration
(make config/xconfig/menuconfig).
Is this kernel configuration standard on most x86_64 installations?
Or is compilation of a custom kernel typically necessary?
Please send me your kernel config file.

ioctl (and ioctl32) is a system function for open and use the /dev special
file (for example ttySL0, slusb ..., is one function for kernel module <->
user program comunication).
