Why Driver not loading into FC13 64bit machine ?

Hi All,

I written a fpga driver, It's compiled and loaded into my local fedora13 32bit machine with out any issues.
My local pc uname -a output :Linux localhost.localdomain #1 SMP Thu May 6 18:27:11 UTC 2010 i686 i686 i386 GNU/Linux

But the same code is compiling without any errors on fedora13 64bit machine but not able to load into kernel (sudo insmod ./bfpga.ko), giving the below error.

insmod: error inserting './bfpga.ko': -1 Invalid module format
64bit machine uname -a output is : Linux localhost.localdomain #1 SMP Thu May 6 18:09:49 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

can any one help me why this error? Did i need some thing to do for 64bit machine?

Thanks in advance.

besides the fact that fedora 13 has been UNSUPPORTED of 7 months now, and NEVER will receive updates .
it is advised NOT TO USE IT -- it is DEAD ( end of life ).

please stay current and install fedora 16

did you install the 64 bit kernel-devel
and the full required lib's

-- on the 64 bit machine --
yum groupinstall "Development Libraries"  "Development Tools"
yum install kernel-devel


devicedrivers, linux
