Encountered while compiling a new kernel and modules for ClearOS 6.2 kernel 2.6.32-279.2.1.v6.x86_64 to obtain the one wireless module that isn't offered (naturally):
scripts/kconfig/conf -s arch/x86/Kconfig CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 CALL scripts/checksyscalls.sh CHK include/linux/compile.h CC crypto/signature/ksign-publickey.o crypto/signature/ksign-publickey.c:2:17: error: key.h: No such file or directory crypto/signature/ksign-publickey.c: In function ksign_init: crypto/signature/ksign-publickey.c:10: error: ksign_def_public_key undeclared (first use in this function) crypto/signature/ksign-publickey.c:10: error: (Each undeclared identifier is reported only once crypto/signature/ksign-publickey.c:10: error: for each function it appears in.) crypto/signature/ksign-publickey.c:11: error: ksign_def_public_key_size undeclared (first use in this function) make: *** [crypto/signature/ksign-publickey.o] Error 1 make: *** [crypto/signature] Error 2 make: *** [crypto] Error 2
Thanks to this post:
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.
Now I just have to cross my paws that this is still a simple matter of compiling a module and not the slightly messier matter of replacing the kernel image as well.
