Bug Description

gcc-4.1 in edgy has now -fstack-protector on by default. Today I tried to compile a kernel and failed. It looked like it couldn't find the stack protector functions / library.
I had to add -fno-stack-protector to the other flags to compile the kernel succesfully.
So either add -fno-stack-protector when building a kernel or gcc shouldn't use -fstack-protector on kernel builds (if it's possible)

Revision history for this message
Ben Collins (ben-collins) wrote :

kernel-package does not choose compile time options. This is the responsibility of the kernel. There is a patch in recent kernels that includes -fno-stack-protector, and the Ubuntu kernel itself supports this aswell.

To avoid it, install gcc-4.0, and set CC=gcc-4.0. Or add the flags manually to the kernel Makefile.
