I'm not sure if this explains all the problems, but it looks as if the system symbol table in "System.map" is missing, or not current/correct.

ljishen commented 7 years ago

Thanks. I solved this problem by installing some modules. Now the make process didn't complain any undefined WARNINGs.

However, when I run sudo modprobe -v 8723bu, it gives Exec format error.

The related message from dmesg is: cfg80211: exports duplicate symbol __cfg80211_alloc_event_skb (owned by kernel)

The lsmod shows empty current loaded module.

lwfinger commented 7 years ago

That message seems to indicate that cfg80211 is built in AND a module. Check your .config.

inklit commented 6 years ago

@ljishen Can you tell me what you did to solve the problem? What modules did you install? I am having the same issue but nobody has stated what fixes it.

ljishen commented 6 years ago

@inklit My solution was that I got the source tree of the running system and use cat /proc/config.gz | gunzip > .config to obtain a "correct" configuration file for the kernel compiling.
