kldload issue: "Exec format error" with amd64 FreeBSD

[Yong Rao]

Hi,

 

I am porting a device driver from 32 bit FreeBSD OS (6.2) to amd64
(6.2-RELEASE-p7).

The compiling passed without any problem. But while I do kldload the
module, we got problem.

 

kldload: can't load ./pnicdrv.ko: Exec format error

 

the dmesg displayed

 

kldload: Unsupported file type

kldload: unexpected relocation type 7

link_elf: symbol strcpy undefined

 

What the problem is?

 

In the compiling option we added extra "-m64 -fPIC ...". What particular
options/flags else we should add in?

Is there example makefile(device driver code set) we can refer to?

 

Thanks a lot,
