I got this message during compiling module.
Building modules, stage 2. MODPOST WARNING: "tasklist_lock" [ /Red/src/Red.ko] undefined! make[1]: Leaving directory `/usr/src/linux-headers-2.6.18-4-686' Actually, Red.ko had made but can not load the module due to the unknown symbol (tasklist_lock). What’s the problem?? I can see the symbol is exported in the linux-header-2.6.18-4-686/include/linux/sched.h. I couldn’t understand why it is shown “undefined”?? Also during searching about this problem, I read this - for linux kernel 2.6.18, the symbol does NOT export any more …. Is this right??? If it is, is there any way to use the symbol ‘tasklist_lock’? There is my only guess, it is needed the license to use this symbol. Thanks a lot for any suggestion.
