Hi,

I've written a kernel mode driver using WinDriver and as part of this I need to call an equation which contains a double type. I then cast this to a DWORD so I can send the result to my PCI card. However when I compile I get the following:

Linking Executable - objfre_winnt\i386\free\kp_elm.sys for i386
kp_elm.obj() : error LNK2001: unresolved external symbol __fltused
kp_elm.obj() : error LNK2001: unresolved external symbol __ftol
objfre_winnt\i386\free\kp_elm.sys() : error LNK1120: 2 unresolved externals

Can anyone help?
