Ubuntu – Kernel doesn’t support PIC mode for compiling


I've been trying to compile the latest Linux v4.8.9 kernel on Ubuntu 16.10 and this error keeps popping up after I've made the default .config, modified it with menuconfig and ran make by itself. I've also run make mrproper as soon as I untarred the file. This is the output right after I run make:

I've also tried compiling with the -no-pie option after the make command but it renders a set of new errors, constantly saying that there are "missing targets". I have gcc version 6.2.0. I also have gcc-5 installed because I assumed in the beginning it might be because gcc was too new but the same problem persists in gcc-5. Someone in the mailing lists or another forum mentioned that the problem was resolved by directly cloning from git but that didn't help in my scenario either.

I'm curious if anyone else has run into this problem and if so, what a possible fix might be?

NOTE:I'm running Ubuntu in Virtualbox on a Mac if that might be a possible source of problems.

The issue is with your gcc installation, in gcc 6+ versions PIE( position independent executables) is enabled by default. So in order to compile you need to disable it. Even gcc 5 has the issue. This is a known bug for gcc. Bug Link.

So far there is no official patch from gcc side, so the workaround is to patch the Makefile of kernel source.

If you are familiar with patching the source file use the codes from this link to create the patch file then try to compile.Patch File

Let me know if you are having difficulties installing the patch.
