Binaries for RaspberryPi or other ARM devices?

[desrever]

how hard is it to compile BerkeleyDB4.8 on the Pi?

Oh, wait, I’m outdated here as I didn’t follow all discussions this summer. To build nud 2.0.1, I didn’t do anything different from 1.2.0, just an apt-get upgrade. englighten me please

[masterOfDisaster]

For new versions of Raspbian¹ (required for RaspberryPi2) there’s only BerkeleyDB5.1 (or newer) in the standard repositories (sudo apt-get install libdb5.1++-dev).
You might try sudo apt-cache search libdb4 - I don’t get anything useful for my Pi.
So you need to download and compile BerkeleyDB from the source.
Maybe I try to find out how hard it is

With libdb5.1 you convert the wallet file and some other files to a format that is not backwards compatible with libdb4.8 (which will be used for the official releases).
So after you compiled nud with libdb5.1 and started nud, your Nu files are in a nu format that isn’t compatible with official releases.

Thanks for the explanation, I had no idea. That’s also why I preferred calling it unofficial builds …

To make the nud builds I used a rpi2 (raspian 3.18.11-v7+ ) , therefore I guess I built with BerkeleyDB5.1 (any tips to check the version od berkeleydb installed?) .

Looks like next week I’ll have to 1) figure how to uninstall bdb5 2)download and build bdb4 3) rebuild nud and update the tutorial and builds.

Thank you, that’s kind but not necessary.
@sigmike told me about the libdb:

Mandatory upgrade to Nu 2.0 by August 25th

Note that a wallet created with this version of the library will not work on the official build. It’s not a problem if you intend to always use the wallet with this version (or a later one), but if you ever have to run the official build it won’t be able to read your wallet file. See this message for an explanation: https://bitcointalk.org/index.php?topic=381162.msg4093527#msg4093527 You can use the bitcoin ppa to get the libdb4.8+±dev package that is compatible with the official build: htt…

The repository he linked unfortunately doesn’t offer packages for ARM CPUs…
…and I still have no cross compiling environment available - that is waaaay beyond my skill
Thanks to the speed of the RaspberryPi2 it’s no longer such a pain in the *** to compile on it.

Looks like next week I’ll have to 1) figure how to uninstall bdb5 2)download and build bdb4 3) rebuild nud and update the tutorial and builds.

I gave it a try, but failed. Somehow I was not able to completely remove libdb5.1 or at least make the nud compile use the libdb4.8.
When I find the time I make a fresh install of Raspbian on the Pi and test again.

[desrever]

you could try this (source)

Download the Berkeley DB, uncompress it, and cd into the uncompressed directory:

wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
tar -xzvf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix/

Then, configure the system for compiling, do the actual compile job with make (will take a good while), and then install Berkeley DB:

../dist/configure --enable-cxx
make
sudo make install

You guys can just add the bitcoin repository which provides access to 4.8. I thought I had documented that somewhere. It’s in the peershares wiki. https://github.com/Peershares/Peershares/wiki/Linux

sudo apt-add-repository ppa:bitcoin/bitcoin

sudo apt-get update

then you can just

sudo apt-get install libdb4.8++-dev

isn’t that what you’re looking for? This is what I was using when I was providing ARM builds for everyone before we went open source.

[masterOfDisaster]

Awesome!
@assistant tip 2 @CoinGame

ninjaedit: sometimes the assistant does strange things… I wonder why he revived an old conversation to tell me… anyway - I’m glad it worked.
Hey, @desrever, looks like I have more NBT ere under my assistant’s control

edit2: first you need to make apt-add… available:

sudo apt-get install python-software-properties

edit3: nope, doesn’t work that way; http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu/dists/ doesn’t have “wheezy” listed. This causes an error when trying to use this repository:

http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu/dists/wheezy/main/binary-armhf/Packages  404  Not Found

[desrever]

so now the question is how to uninstall bdb5, right? Or will atp-get take care of it?

[masterOfDisaster]

I remember that I encountered problems trying to completely uninstall libdb5.1.
There was an error message that made me shy away from going on with it, although I don’t remember the words…

[CoinGame]

sudo apt-get remove bdb5 (or whatever the package name is) didn’t work?

[Sabreiib]

keep it simple, stupid.

Common users of Nu won’t do such research. How about provide binaries for raspi 1B and 2B respectively? So that users can open the box and copy, run.

[masterOfDisaster]

I haven’t found a single trustworthy repository with libdb8.8 still available for ARM on wheezy.

If you don’t want to go the compiling way and trust bittylicious, you might want to take this route

wget https://bittylicious.com/downloads/libdb4.8_4.8.30-11ubuntu1_armhf.deb
wget https://bittylicious.com/downloads/libdb4.8++_4.8.30-10precise1_armhf.deb
wget https://bittylicious.com/downloads/libdb4.8-dev_4.8.30-11ubuntu1_armhf.deb
wget https://bittylicious.com/downloads/libdb4.8++-dev_4.8.30-10precise1_armhf.deb

sudo dpkg -i libdb4.8_4.8.30-11ubuntu1_armhf.deb
sudo dpkg -i libdb4.8++_4.8.30-10precise1_armhf.deb
sudo dpkg -i libdb4.8-dev_4.8.30-11ubuntu1_armhf.deb
sudo dpkg -i libdb4.8++-dev_4.8.30-10precise1_armhf.deb

[CoinGame]

These changes must all be recent. As I said before I was using the bitcoin repository with no problems on raspbian. Oh well.

[masterOfDisaster]

Sigh.

Trying to completely remove libdb5.1 doesn’t look like a good idea:

After this operation, 863 MB disk space will be freed.
You are about to do something potentially harmful.
To continue type in the phrase 'Yes, do as I say!'

At least Raspbian warns that this is going to damage the system and asks to type a complete sentence to continue…

[CoinGame]

Do it do it do it

[desrever]

Is the wallet format also affected?

[masterOfDisaster]

I recommend not to do it.
I did it.
The system is unusable after even being completely done with it.
It gets stuck at a “PAM configuration” which asks for a “PAM profile”. Rebooting is the only option. But that doesn’t solve the problem. The operating system is done after trying to remove libdb5.1.

[CoinGame]

Your sacrifice will not be forgotten. :salute:
