Creating offline wallet on raspberry pi

[JekyllIsland]

I thought this would be a fun little project and more productive then having 15-20+ paper wallets. Sadly i'm not as competent with computers as most of you here, although I can usually manage after a few hours of frustration. I was hoping somebody, or a few people could help dumb this down for me so i can understand it. Below I posted everything I’m supposed to do; assuming i don't encounter problems along the way.  At the moment I’m stuck on step 18. of this tutorial www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/

18. Just add your compiler directory to your $PATH and start compiling. If you used my preferred prefix directory, you would want to add /opt/cross/x-tools/arm-unknown-linux-gnueabi/bin.

I have ubuntu as my operating system for my raspberry pi, but i'm not sure exactly how to move the compiler directory to the raspberry pi, or even exactly what the $PATH is.   


Now give your compiler a quick sanity check:

Code:

bootc@tarquin ~ $ arm-unknown-linux-gnueabi-gcc --version
arm-unknown-linux-gnueabi-gcc (crosstool-NG 1.15.2) 4.6.4 20120402 (prerelease)
Copyright (C) 2011 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

Code:

bootc@tarquin ~ $ cat > test.c
#include <stdio.h>
int main() { printf("Hello, world!\n"); return 0; }
^D
bootc@tarquin ~ $ arm-unknown-linux-gnueabi-gcc -o test test.c
bootc@tarquin ~ $

Copy over the newly compiled test program to your Raspberry Pi and run it. You should see:

bootc@raspberrypi:~$ ./test
Hello, world!
bootc@raspberrypi:~$

Here is the next tutorial, https://gist.github.com/FiloSottile/3646033 I'm stuck on applying the patch.

Now that you have your arm-unknown-linux-gnueabi-g++ working in your $PATH, clone the Armory repo

Code:

git clone git://github.com/etotheipi/BitcoinArmory.git
cd BitcoinArmory

This is the next step i don't understand exactly, how do i apply the patch to the two make files? Obviously i save it as CXX.patch, but what next?

Apply the attached patch to the two Makefiles (a smarter patch might be merged in the repo in the future)

Code:

patch -p1 < CXX.patch

Code:

And MAKE

Code:

CXX=arm-unknown-linux-gnueabi-g++ make

Finally, create a tarball to move to your shiny Raspberry

Code:

mkdir -p BitcoinArmoryRPi/img/
cp *.py *.so README LICENSE BitcoinArmoryRPi/
cp img/* BitcoinArmoryRPi/img/
tar cvfz BitcoinArmoryRPi.tar.gz BitcoinArmoryRPi

Any help is greatly appreciated

In order to add something to your path, go to your home directory, and edit ~/.profile with your favourite editor. I use nano for simplicity:

Code:

nano ~/.profile

Find the following line

Code:

PATH="$HOME/bin:$PATH"

Add change that line to include the directory. It should be:

Code:

PATH="$HOME/bin:$PATH:/opt/cross/x-tools/arm-unknown-linux-gnueabi/bin"

If something is already defined (Meaning it is not the "PATH="$HOME/bin:$PATH"") just add a colon and enter the same path above).

Let us know if you need any additional help.

You can also use .bashrc using the export command, see http://askubuntu.com/questions/60218/how-to-add-a-directory-to-my-path for more info (This may be more recommended).

Run
source .bashrc afterwards.
