Issue while compiling gcc-5.2.0

Question

I am trying to build my own lfs system for Raspberry PI 2.

As a part of it I am trying to compile gcc on Raspberry PI 2, with raspbian as a base operating system.

I could build the binutils using the instructions on lfs development version. But while compiling gcc I am getting below error

I tried to trace the cause of error by looking at the expr.c file, but could not find issue. I have uploaded the "/tmp/ccAUc9Pu.out" to http://turl.ca/dcfansr

Can someone please help me how to debug the exact cause of issue

Answer 1

I had the same problem after checking all the system requirements were installed by running the version check at http://www.linuxfromscratch.org/lfs/view/stable-systemd/prologue/hostreqs.html and rebooting the system it worked afterwards.
