Hi sir... What other perl modules are needed along with Sys::Info::0.63, to get the Sys information.? I could get the System information, but i had to add from Unix::Processors (directory)..Processors.pm module and i686-linux (directory) config.pm module and DynaLoader.pm .. when i was trying on Linux machine, but for windows ...i dont need them... so if we need to get the System information for any other Operating system, do we need to add some modules specific to that Operating system??? Will not the Sys::Info module, directly give me the information ....???..do i need to add other modules??? i am mostly interested in getting CPU count.... Thanks in Advance.
