RE First
#include <linux/version.h>
--- Yes so I discovered and bypassed in my attempts. Under 2.6.17 code, config.h just says use autoconf.h instead. This is also what my code piece below achieves under 2.6.18 The autoconf.h is basically the /boot/config-KernelVersion file in C code format. Why the lethal "Floating point exception" occurs under 2.6.18, but not 2.6.17 compilations is certainly not transparent. MarvS On 1/17/07, Joern Wuestenfeld <j.wuestenfeld@xxxxxx> wrote:
Hello, I tried this because of having the same problem with another driver. But one has to make sure that #include <linux/version.h> is above the #if KERNEL_VERSION_CODE! Otherwise the variable and the macro are not defined!
