Hi all, I have a laptop with FC5, kernel-2.6.17-1.2174_FC5 and wireless-tools-28-0.pre13.5.1. I need to do a particular program that use structures and variables of wireless extensions (WE) v19 but when I tried to compile my program I got several errors pointing that such structures and variables aren't recognized. I have noticed that I have several version of wireless.h, as the following: /usr/include/linux/wireless.h --> WE-16 /usr/include/wireless.h --> WE-19 /usr/src/kernels/kernel-2.6.17-1.2174_FC5-i686/include/linux/wireless.h --> WE-20 In my program I have included: #include <linux/wireless.h> and I understand that the compiler is trying to use WE-16. I have tryed to give a solution doing: # cd /usr/include/linux # rm wireless.h # ln -s ../wireless.h . But the problem wasn't solved. Could you give me some ideas in order to find the solution? Cheers, Johnny
