[driverloader] Driverloader won't build module because of bogus error reported by kernelcompiler.sh

Thu Dec 2 09:56:41 EST 2004

Hi,

as Stefan added, gcc 2.96 is probably on the CDs of Mandrakelinux. You 
could try the 'urpmi gcc' command in a root shell to install it.

For compiling kernel modules, you need the exact same version of gcc 
that was used to compile the kernel or else it will not work. Since your 
kernel was compiled with gcc 2.96, you need to install 2.96 or else it 
will not work, even if you have installed a newer version of gcc and you 
modify our script. This is not a limitation of DriverLoader but a 
limitation of the Linux kernel and/or gcc.
