1. Try upgrading your GCC compiler to 4.3.2 2. To avoid Division in code: try using shift operation instead of div. E.g. "c = c >> x" instead of "c = c / x;" Regards Vivek -----Original Message----- From: kernelnewbies-bounce@xxxxxxxxxxxx [mailto:kernelnewbies-bounce@xxxxxxxxxxxx] On Behalf Of Sukanto Ghosh Sent: Thursday, February 05, 2009 10:56 AM To: Manish Katiyar Cc: kernelnewbies@xxxxxxxxxxxx Subject: Re: Division involving u64 : undefined reference to __udivdi3 > Have a look at the file arch/x86/include/asm/div64.h. That might help > Thanks Manish. I was trying to use the macro do_div defined in that file. But when I am trying to divide two u64 values using that, I am not getting the correct quotient. I am using it like this: u64, a,b,c; /* for c = a/b */ c = a; do_div(c,b); -- Regards, Sukanto Ghosh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
