编译内核出现以下错误
Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at kernel/timeconst.pl line 373.
/root/working/Hi3520D_SDK_V2.0.3.0/osdrv/kernel/linux-3.0.y/kernel/Makefile:140: recipe for target 'kernel/timeconst.h' failed
make[1]: *** [kernel/timeconst.h] Error 255
Makefile:945: recipe for target 'kernel' failed
make: *** [kernel] Error 2
解决办法：
将kernel/timeconst.pl中第373行的defined()去掉只留下@val就可以了
