I was trying to compile kernel on my system by following this link http://www.ramkitech.com/2012/04/how-to-compile-kernel-step-by-step.html

when I run make command, I am getting the following error

 writing new private key to 'signing_key.priv'
Illegal instruction (core dumped)
make[1]: *** [signing_key.x509] Error 132
make: *** [kernel] Error 2

Can you please help me to solve this error and build my kernel (linux-3.18.20).

I am using Ubuntu 14.04 LTS 32bit (kernel 3.13.0-24-generic), downloaded kernel source from kernel.org (latest kernel linux-3.18.20)

Your processor attempted to execute an instruction it doesn't recognize in OpenSSL. This may be an issue with your OpenSSL installation.

Illegal instruction (core dumped)
  • Make sure OpenSSL isn't compiled for the wrong CPU architecture. It's possible that your copy of OpenSSL is compiled for a newer CPU and your CPU doesn't support certain newer instructions such as one of the SSE instruction sets.

  • If this isn't the case, your OpenSSL installation may be corrupt and you may need to reinstall it.

  • There was issue with Openssl version. As per your suggestion I have reinstalled openssl and now I am able to compile my kernel. Thanks. – bholanath Aug 28 '15 at 10:25
