RPi2 | Compiling of TVheadend fails due to undefined reference to `__sync_lock_test_and_set_8' in function `atomic_exchange_s64'

Added by Bernardo Gui almost 9 years ago

Hello world,

I'm trying to make TVheadend (cloned respository 2h ago) work on my RPi2 running Raspian Wheezy, but after running

AUTOBUILD_CONFIGURE_EXTRA=--disable-libav_static ./Autobuild.sh

the process crashes with the following error messages:
[...]

I've found a way out by doing

cd tvheadend
CC=gcc-4.7 ./configure --disable-avahi
make 
sudo make install

and following the further instructions provided at http://www.forum-raspberrypi.de/Thread-tutorial-tvheadend-kompilieren

Since I have no idea what this gcc-4.7 did I'm eager to learn what this did and what the issue with atomic.h was.
