Using kernel-smp-2174, I can't get past the following error. I have tried without first installing ieee80211-1.1.14 and after installing it. I have re-installing the kernel in between attempts, but have come to the conclusion that I am making a mistake somewhere. WARNING: Your kernel contains ieee80211 symbol definitions and you are not using the kernel's default ieee80211 subsystem. (Perhaps you used the out-of-tree ieee80211 subsystem's 'make install' or have provided a path to the ieee80211 subsystem via IEEE80211_INC.) If you wish to use the out-of-tree ieee80211 subsystem then it is recommended to use that projects' "make patch_kernel" facility and rebuild your kernel to update the Module symbol version information. Failure to do this may result in build warnings and unexpected behavior when running modules which rely on the ieee80211 subsystem. Aborting the build. You can force the build to continue by adding: IEEE80211_IGNORE_DUPLICATE=y to your make command line. make: *** [check_inc] Error 1 I would be grateful for any help. DP South Australia
