Can't sync further than block 600000 on RPi2

Hey guys, long time no see.

I've been trying to get the daemon running on my RPi2, but as the title says, it can't go further than block 600000.

This is what I'm getting on the daemon with log level 1:

It keeps trying and trying but won't accept that block.

I've also noticed that previously, when launching the daemon it would say "Loading precomputed blocks: 600000" as in this snippet:

2015-Sep-11 04:14:35.397710 option: fastest

2015-Sep-11 04:16:03.501039 Core initialized OK

But now that I'm on block 599999, trying to get 600000, that message is no longer displayed.

Any ideas?

EDIT to add:

I'm using Ubuntu MATE 15.04 with libdb 5.3.21

Also, I want to mention that with this exact same configuration on x86 32-bit it works (not sure now if libdb was exaclty 5.3.21, but definitely 5.3).

SOLVED! I Built it with gcc 4.8 instead of 4.9, which is the default in Ubuntu 15.04, ran the daemon again and it continued syncing with the network.

can you post the commands to fix the gcc version? I remember googling it once, and its not a particulary straightforward venture.

Sure! This is what I did:

sudo apt-get install gcc-4.8
cd /usr/bin
sudo rm gcc
sudo rm g++
sudo ln -s gcc-4.8 gcc
sudo ln -s g++-4.8 g++

"funny" because the current bitcoin also needs Berkeley db in the ver 4.8

GCC needs to be 4.8, not BerkeleyDB (right now I'm using BerkeleyDB 6.1), and this happens only on RPi2 (probably on other ARM devices too). GCC 4.9 and BerkeleyDB 5.3 on x86 32-bit works just fine.

I tried again with BerkeleyDB 6.1, same result.
