gcc 4.6 "Seems to be a completely non-functional toolchain"

[Steven Valsesia]

When i try to compile a hello world, I get that :

pi@raspberry ~/prog/test $ gcc test.c -o test
gcc: internal compiler error: Illegal instruction (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.

When i try to use gcc-4.4, it works !!!

4.6.3-14+rpi1 -> don't works.
4.4.7-3+rpi1 -> works.

Here is the test.i :

# 1 "test.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.c"
# 1 "/usr/include/stdio.h" 1 3 4

My Linux :

Linux raspberry 3.6.11+ #538 PREEMPT Fri Aug 30 20:42:08 BST 2013 armv6l GNU/Linux

I first send a bug report for gcc ( http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59887 ), and Richard Biener tell me "Seems to be a completely non-functional toolchain. Report a bug to where you got it from."

EDIT: I think that bug happenned after my installation of gdc (gnu D compiler). Can it be the cause of my broken gcc ?

Thanks !

If gcc 4.6 (the default compiler) was generally broken in raspbian I think we would have found out a long time ago so there must be something going on on your Pi that is breaking things and that does not apply to the majority of Pis out there .

Do you have a copy of the program that failed?
How did you attempt to install gdc 4.6? from a package? from source?

[Steven Valsesia (steven-valsesia)]

I posted here because I think it's "# apt-get update ; apt-get install gdc" who did that !

Plus, I don't understand why gcc-4.4 works normally... :(

The program i try to build is just an hello world !

Thank you !

Can you post the output of

cat /etc/apt/sources.list /etc/apt/sources.list.d/*
dpkg -l gdc gdc-4.6 gdc-4.8 gcc gcc-4.6 gcc-4.8

I think I find what's going on,

root@raspberry:/home/pi# reboot

The system is going down for reboot NOW!

My raspberry is definitely dead ?

What's the current status? Any new developments?

[Steven Valsesia (steven-valsesia)]

Sorry, this bug report was a mistake.
Errors was due to bad sectors on the sd card.
