[Freeswitch-docs] raspberry pi compiler issue

[Russell Treleaven]

Hi,

I write this in hopes that someone will review it and add it to the wiki.
-------------------

Attention: raspberry pi users

There is a bug in the compiler that ships with raspbian 7.6
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61509 for details

One of the symptoms of this bug is

This bug has been fixed in gcc 4.7 or higher

To upgrade gcc do
apt-get update
apt-get dist-upgrade
To verify the compiler version do
gcc --version
#version should be "gcc (Debian 4.7.2-5+rpi1) 4.7.2" or higher
