If do not set -O2 to kernel compile option , I will get somw error aue to several symboles
is undefined reference to ,for example:
in ext3/super.c : undefined reference to `ntohl'
I take a lppk at the definition in source code for ntohl, it seems affected
by the __OPTIMIZE__ macro , which make this symbole defined as a macro .just
like this : #define ntohl(x) ___ntohl(x)
But if I do not define __OPTIMIZE__ ,which means I need not any optimization,
How can I compile successfully? Is there the corresponding ntohl() function in kernel ?
I kave not found that yet. Does this mean I must use __OPTIMIZE__ by -O2 ?
thanks!
