Description Otamay 2011-04-25 23:15:16 UTC 
Similar to Bug 183062 , kexec built with CFLAGS="-fPIC" fails to load any kernel image, resulting in "Unhandled rela relocation: R_X86_64_PLT32".

Filtering the -fPIC flag allows kexec to successfully load any kernel capable of.


Reproducible: Always

Steps to Reproduce:
1. Build sys-apps/kexec-tools-2.0.2-r1 with CFLAGS="-fPIC"
2. Load a kernel with kexec -l /boot/vmlinuz
3. Chech the resulting error.
Actual Results:  
Unhandled rela relocation: R_X86_64_PLT32

Expected Results:  
No error, kernel loaded and ready to a reboot.

Gentoo GNU/Linux on an AMD64 processor.

Dirty patch for sys-apps/kexec-tools-2.0.2-r1.ebuild

Proposed dirty patch for sys-apps/kexec-tools-2.0.2-r1.ebuild, to filter the -fPIC cflag allowing a built kexec capable to load kernels capable of.

Do not add -fPIC to your flags unconditionally, such a situation is not supported.
