64 bits division on a Raspberry Pi (ARM 32 bits)

581 Views Asked by At

I'm trying to cross-compile a kernel module for Raspberry. In this module, I need to divide two 64 bits unsigned int. The compilation works, but there's this warning : WARNING: "__aeabi_ldivmod" undefined !

And when I try to insmod the module, it obviously refuses to insmod, because of this undefined symbol.

Do you guys know how I can divide those 64 bits uints ?
