Sorry to keep poking this thread, but I do want to make sure this is right, and I don't have an RPi setup to test (I do have one, but I've never set it up):

Thanks for the quick response, etotheipi! That download worked perfectly for me.

That first launch error is silly. We've seen it like 3 times out of 200 launches: it simply prevents Armory from opening that one time, then goes away the next time. I'd love to isolate it, but we can't reproduce it. Maybe one day.

As for the wallet error... it's somehow reading a zero-length key. Perhaps the there was wallet corruption after you made the decrypted backup? I'm not sure -- as you can see it's a little thrown off by the duplicate wallet in the .armory directory... it's not intended to store multiple, duplicate wallets there -- you're supposed to make the decrypted backup to a removable drive or something.

Of course it's supposed to work. Somehow the original wallet is corrupted...? Maybe you could backup those wallets (in case we need to debug it later) and simply try out all the other operations? It would be good to know if everything else works as expected, and then we can figure out what happened with those wallets later.

2nd launch it starts ok. I could create a new wallet, make a paper backup and verify it.
Exporting as an decrypted wallet works when not exporting to the .Armory dir.
I did not try to import the decrypted wallet.

Extracting in .Armory dir produces an crash:

just wondering how you've got it to compile as i had to replace the Makefile from the cryptopp folder with the GNUmakefile from the source of cryptopp in order to compile it on the Pi.

https://bitcointalksearch.org/topic/m.1906666

You're probably building the master branch, which doesn't have the changes made to the cryptopp makefile.

Thanks, that's it.

I just used "git clone git://github.com/etotheipi/BitcoinArmory.git" to get the source, was to lazy to look for a Branch Wink

I can create a new wallet, make a paper backup and verify it, get a new receiving address, create and import a watching only wallet, ..., seems to be working.

I gonna try it on a fresh install of Raspbian as for now i tested it on the system where i also compiled the other version, just to make sure of any other missing dependency.

That tar.gz doesn't have the dependences with it. It assumes all the dependencies are already there. We've been swamped with some other things, so we weren't able to create a full bundle for it, but knew that the compile step was a real PITA, so this helps get over the biggest hurdle.

Hi,

i had the same problem before and ended up building 0.90 from the source on the Pi Roll Eyes

This new version seems to work, at least it starts without problem and shows the same wallets as before.
(I just started/ended it on the Pi, nothing more)

Hope this helps.

You could try something like creating a paperback up of one of your wallets. If it gets that far (unlocking and all) it should be sound for signing.

I bet I botched the build process and compiled for i386 instead of armhf. We verified the build process worked, and then I made a script to make it easier, but I bet I did the script wrong.

I'm about to put out 0.91.1 with some tweaks to the wallet-fixing logic and the new Bitcoin Core download. I'll see if I can fix the RPi cross-compile script.

It looks like that's exactly what happened, I accidentally use the i386 g++ instead of the armhf g++.

The old one:

Code:

~/temp/armory_rpi/usr/lib/armory $ file _CppBlockUtils.so 
_CppBlockUtils.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=0x1e56789efad37396cf2ae2f426ccbd6f0751e2e0, not stripped

Now that I did it manually and verified the correct compiler was being used:

Code:

~/projects/bitcoin/compiledrpi/usr/lib/armory $ file _CppBlockUtils.so 
_CppBlockUtils.so: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped

I'll update the RPi cross-compile script and have a new version along with everything else, soon.

I dont think we put out a 0.91 RPi package yet. The debian/ubuntu packages certainly won't run on a Pi, different CPU arch.

Hello.

I'm having trouble installing Armory 0.91 on my Raspberry Pi, which is running Raspbian. I would appreciate some help.

Here is the error I get when I try to launch Armory:

Code:

pi@raspberrypi ~ $ python /usr/lib/armory/ArmoryQt.py --offline

I am not sure why that error is happening because I definitely have /usr/lib/armory/_CppBlockUtils.so. Here is a full listing of the files in /usr/lib/armory:

Here is the sha256sum of my _CppBlockUtils.so (I have not verified that this is what it should be):

Code:

388f0e509ab77e7e86c9de315eaceaae8bb46f43322ecd4ee6425ca62519f1e3

I tried running the following command but still got the same error:

Code:

LD_LIBRARY_PATH=/usr/lib/armory python /usr/lib/armory/ArmoryQt.py --offline

I suspect that the error message is misleading and that the actual problem is that one of the dependencies of _CppBlockUtils.so is missing.

Here is what I have done so far to set up this system:

I downloaded armory-0.91-beta_raspbian.tar.gz from bitcoinarmory.com. I used sha256sum and gpg to verify that I have the right thing.

I installed Raspbian on my Raspberry Pi using NOOBS 1.3.4.

I installed armory by copying the files inside the armory_rpi folder to /.

I have installed all the prerequisites listed in Armory's README using apt-get except for qt4reactor; I have not yet figured out how to install that on the Raspberry Pi but I don't think it is relevant to this error.

Is there anything else I need to do? I could not find step-by-step instructions for the Raspberry Pi so I might have missed something.
