Kernel compile errors

Hello! I've tried several different setup and version of kernels to be compiled on my system but all of them gave me an error when I got the make modules_install. It just installs a couple of files and then gives error 2 messages (always when it came to ipfiltering or something similar) I tried kernel 2.4.19, 2.4.18, 2.4.16 and currently I am compiling the SuSE 2.4.12 kernel (part of 7.3) to see if this one will work at all. Is this a typical error newbies make or are my sources bad? I would really love to compile kernel 2.4.19 since it already includes the driver for my formac proformance 3 stephan
