Updated: added "protobuf-compiler" as dependency.

I was able to compile with Qt on Ubuntu 12.04 LTS:

How to disable downloading of blockchain?
Is this possible to download dump of the blockchain and put it on external USB drive?

I am fine up to line 49 "./src/bitcoind" but then I get the error message as following:

alok@as-Thinkpad:~/bitcoin$ ./src/bitcoind
: Incorrect or no genesis block found. Wrong datadir for network?

Any help please?

I needed to install libevent-dev and libqt5core5a
Thanks for this guide!

@asubbarao: you just remove ~/.bitcoin directory with cmd "rm -rf ~./bitcoin"

I needed to install libevent-dev and libqt5core5a

I am running Ubuntu 16.04.2 LTS and also needed to install libqt5core5a.

Additionally, I had compiler issues when I attempted:
make -s -j5

This solution worked for me:
https://bitcointalk.org/index.php?topic=304389.0

free
dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
mkswap /var/swap.img
swapon /var/swap.img
free
make -f Makefile 

Here is what I did for ubuntu 16:

sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install -y libdb4.8-dev libdb4.8++-dev

Worked great, for ubuntu 16, had to add libevent-dev, and libqt5core5a instead of libqt5core5.

thanks

After entering line 33: (../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/theusername/bitcoin/db4/) I get:

configure: error: libdb_cxx headers missing, Bitcoin Core requires this library for wallet functionality

Edit: Ubuntu 16.04.3 LTS

Thanks for this.

I'm stuck at line 42, Compile Bitcoin with Berkley DB 4.8, I get: -bash: ./configure: No such file or directory

Any help???

solution works for me on Ubuntu 16.04:

sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install -y libdb4.8-dev libdb4.8++-dev

i've been trying

However the following packages replace it:
libqt5core5a

E: Package 'libqt5core5' has no installation candidate

Update this to document

@caikehe It works! thx

in Ubuntu 16 you also need to run

sudo apt-get install libevent-dev

Excellent work. How does one edit the qt client GUI interface?

Thanks for sharing, after the installation, the software language is garbled and I am getting an error:

If this sounds wrong, possibly the target language is not set or recognized.

what should I do?

Thanks!
