I have an Sm56 Motorola Internal Modem.
I downloaded the driver and installed it,but when I gave the insmod command from inside dev
insmod sm56
but it gave me the error

Using /lib/modules/2.4.21-0.13mdk/kernel/drivers/char/sm56
/lib/modules/2.4.21-0.13mdk/kernel/drivers/char/sm56: The module you are trying to load (/lib/modules/2.4.21-0.13mdk/kernel/drivers/char/sm56) is compiled with a gcc version 2 compiler, while the kernel you are running is compiled with a gcc version 3 compiler. This is known to not work.

The modem was installed successfully,but why doesnt it load?

Do i have to recompile the driver with gcc3?

after this i did modprobe,which too didn't work.

What do i do now?
then i did this
gcc /lib/modules/2.4.21-0.13mdk/kernel/drivers/char/sm56
but it gave an error as saying "cannot open <module...>permission denied ld exit status returned 1"

Thanks,
DC.
PS:I want to surf the net in Linux,Am a newbie so please try to be as clear as you can.Thanks.

Did you compile the driver or install from rpm? If you compiled, you'll have to recompile. If you rpm'd then you'll have to make sure you get the EXACT right one for the version of mandrake that you have. If you can't find one then it's a compile.
