linux内核编译报错

内核2.6.32 编译出现:

ksign_def_public_key’ undeclared

run make menuconfig.
1) Select "Enable loadable module support", then "Module signature verification (EXPERIMENTAL)". Disable it.
2) Then go back to the main menu, select "Cryptographic API" then "In-kernel signature checker (EXPERIMENTAL)" and disable that one too.
Then go back again, save your config and make your kernel. At least, it will pass this phase successfully.
